Percepcija i iskustvo rodne diskriminacije studenata i studentica na Sveučilištu u Zagrebu
Authors: Ćavar Iva , Opačić Ana
Published: October 2023

Cilj ovoga kvantitativnog anketnog istraživanja bio je utvrditi doživljaj i iskustva rodne diskriminacije na Sveučilištu u Zagrebu iz perspektive studenata/ica te doprinos sociodemografskih obilježja i obilježja studiranja u objašnjavanju iskustva, svjedočenja i percepcije rodne diskriminacije. Kao polazište korištene su teorije kongruentnosti uloga i teorija grupne osviještenosti. U istraživanju koje je provedeno 2020. godine sudjelovalo je 274 studenata/ica sa Sveučilišta u Zagrebu. Rezultati su analizirani regresijskom analizom (jednostavna i hijerarhijska regresijska analiza s dodatnom provjerom moderatorskog učinka svjedočenja rodnoj diskriminaciji na odnos između iskustva i percepcije rodne diskriminacije). Rezultati su pokazali da iskustvo rodne diskriminacije postoji na onim studijima gdje je nominalno izjednačen broj studenata i studentica, no postoje određeni džepovi diskriminacije poput biomedicinskih studija i integriranih studija gdje se češće osobno doživljava rodna diskriminacija i svjedoči diskriminaciji drugih. U percepciji i svjedočenju rodne diskriminacije ključan je čimbenik osobno iskustvo koje pomaže izgradnji grupne osviještenosti. Rodni stereotipi najčešći su oblik rodne diskriminacije. Kad govorimo o sadržaju stereotipa, češće se uočavaju rodni stereotipi deskriptivnog karaktera usmjerenog na oba spola, ali i preskriptivni stereotipi koji su usmjereni protiv žena na pozicijama moći. Stoga možemo zaključiti kako je akademsko okruženje iz perspektive studenata i studentica još uvijek obilježeno „staklenim stropom“, i to neovisno o dominantnoj zastupljenosti studentica na sveučilištu. No, iskustvo diskriminacije nije isključivo žensko pitanje te su svakako potrebna dodatna istraživanja kako bi se istražile dimenzije diskriminacije studenata. Rezultati upućuju na potrebu snažnije zastupljenosti teme rodne ravnopravnosti u akademskoj zajednici uz uspostavljanje institucionalne podrške u suzbijanju diskriminacije.

The study of causes of death has been central to some of the most influential studies of the modern mortality decline in the nineteenth and twentieth centuries. The digitization of individual-level cause of-death data has been game-changing, however, the data presents a major challenge: how do we code the thousands of unique strings for analysis in an efficient way? This paper aims to see how far we can get with automated coding based on string similarity. We do this by applying a Jaro Winkler string similarity algorithm in Python (pyjarowinkler) that codes our cause of death data from the Copenhagen Burial Register 1861-1911 to DK1875, a contemporary coding and classification system from nineteenth century Denmark. We then compare the performance of the algorithm to that of a manual (historian) coder in three different ways: at the level of each unique cause-of-death string, at the level of each cause-of-death group and for the overall cause-of-death pattern for all burials in Copenhagen 1861-1911. Our results show that a minimum-effort algorithm coded approximately half of the causes of death correctly compared to the manually coded dataset. This means that the method applied here is not accurate enough to use for actual data analysis of mortality patterns, as it is not possible to examine individual causes within larger causal groups. However, the results are promising for different uses of the method as a help for the manual coder. A way forward could be to use cut-off points of the Jaro-Winkler scores, coding only those causes where the string similarity match is relatively certain or use the automated method to catch most of the initial cases of a certain disease with a very set phrasing, such as cancer. In both cases, the remainder of the unique cause of death strings could then be coded by a manual coder.

Published: October 2023

Hovedbudskap

Permanente hjørnetannsanlegg bør lokaliseres når pasienten har en tannalder tilsvarende 10 år og ved tegn til ektopisk erupsjon bør pasienten henvises til kjeveortoped

Ekstraksjon av melkehjørnetann kan vurderes dersom den permanente hjørnetannen er palatinalt beliggende, og ekstraksjon ved 10-11 års alder øker sannsynligheten for spontankorreksjon

Aktiv fremføring er tidkrevende, men har høy suksessrate og lite komplikasjoner

CBCT kan være et nyttig diagnostisk verktøy, særlig for kartlegging av eventuelle rotresorpsjoner på permanente incisiver, og i forkant av aktiv fremføring av retinerte hjørnetenner med komplisert anatomisk lokalisasjon

CBCT undersøkelser bør begrenses til tilfeller der funn har betydning for og vil kunne endre behandlings­planen

Published: October 2023

Objective: In this retrospective study, we analyzed factors influencing the ongoing pregnancy rate (PR) in women with repeated implantation failure (RIF) undergoing embryo transfer with endometrial receptivity array (ERA).Methods: Eighty-three consecutive personalized embryo transfers (pETs) with ERA, from 54 women with RIF, were selected from June 2020 to April 2022. Vitrified blastocyst transfer was timed based on ERA results.Results: The ongoing PR per pET was 33.7%. Using ERA, the endometrium was identified as pre-receptive in 26 cycles, early receptive in 25 cycles, receptive in 31 cycles, and late receptive in one cycle. With cycles categorized into three receptivity phases (pre-receptive, early receptive, or receptive), no significant differences were found in the clinical PR (27.3%, 55.6%, and 40%, respectively) or ongoing PR (9.1%, 55.6%, and 40%, respectively) after a single blastocyst transfer. Similarly, no significant differences were observed in the clinical PR or ongoing PR after the transfer of two or more blastocysts. Among women with ongoing pregnancy relative to those without, age at first pET was significantly lower (35 years vs. 39 years, p=0.001), while blastocyst score (23 vs. 18, p=0.012) and the proportion of blastocyst scores >18 (71.4% vs. 38.9%, p=0.005) were significantly higher. In multiple logistic regression analysis, the woman’s age (odds ratio [OR], 0.814; 95% confidence interval [CI], 0.706 to 0.940; p=0.005) and blastocyst score >18 (OR, 3.052; 95% CI, 1.075 to 8.665; p=0.036) were identified as significant factors influencing ongoing pregnancy.Conclusion: In pET with ERA, ongoing pregnancy was closely associated with woman’s age and blastocyst quality.

Published: October 2023

NOAA Pacific Marine Environmental Laboratory’s (PMEL’s) approach to tsunami research is unique among such laboratories in that tsunami observations and modeling are under one roof, offering the advantages of enhancing the speed and lowering the cost of developments. Here, we chronicle the history of the transfer of deep-ocean observational and flooding modeling technologies within and outside of NOAA and provide a case study for future transfers. PMEL and partners’ efforts in transferring tsunami technology have been very successful, resulting in improved protection of global communities with high tsunami risk while enhancing the new blue economy. The transfer of observational technology within NOAA required years of effort, while the transfer outside of NOAA only required a patent and license agreement. During the transfer process, three additional generations of observational technologies were created. The transfer of tsunami flooding modeling technology required a validation process for transfer into NOAA operations and an international training program to allow access to the technology by other countries. During this model development, a web-based product was created to simplify the use of and access to these models for both real-time and hazard assessment applications. We present lessons learned from these transfers, including the need for support as long as the technology is in use. The tsunami transfer process created a wealth of economic expansion while protecting coastal citizens from future tsunamis.

Authors:   NOAA PMEL, McPhaden Michael , Connell Kenneth , Foltz Gregory , Perez Renellys , Grissom Karen
Published: October 2023

This paper describes the evolution of the Global Tropical Moored Buoy Array (GTMBA) over the past decade since the last comprehensive and coordinated overview of the Pacific-Atlantic-Indian Ocean system in 2010. GTMBA provides sustained and systematic observations in real time for weather and climate research, forecasting, and assessments. It is maintained through multi-national consortia that support the Tropical Atmosphere Ocean (TAO) Array and the Triangle Trans-Ocean Buoy Network (TRITON) in the Pacific, the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA), and the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) in the Indian Ocean. Phenomena of interest span a wide range of weather and climate timescales, including tropical cyclones, the Madden-Julian Oscillation, the seasonal cycle, monsoon circulations, El Niño-Southern Oscillation, climate variations on decadal timescales, and trends related to climate change. Recent scientific advances enabled by GTMBA are reviewed along with array design changes that respond to new scientific imperatives and operational exigencies, and future directions are discussed.

Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) is a joint research program between the NOAA Pacific Marine Environmental Laboratory and the Alaska Fisheries Science Center (AFSC). FOCI was established by NOAA in 1984 to study the variability in recruitment success of commercially valuable fin and shellfish in Alaskan waters. The project initially studied walleye pollock (Gadus chalcogrammus) in the context of western Gulf of Alaska oceanography and meteorology. Transitioning from FOCI to EcoFOCI, the program broadened into ecosystem research in the North Pacific and US Arctic (including climate), drawing on multiple scientific disciplines, and continuing to match NOAA scientists with academic colleagues working at NOAA’s cooperative institutes and other universities. EcoFOCI is an authoritative provider of scientific information that supports decision-making and environmental stewardship in Alaskan marine ecosystems through collaborative partnerships, innovation, and scientific integrity. Here, we discuss the origins of EcoFOCI and highlight a few of the scientific accomplishments of the program in understanding the drivers and impacts of long-term oceanographic trends, as well as extreme and episodic events, in the Gulf of Alaska and Aleutian Island ecosystems.

Authors:   NOAA PMEL, Wang Muyin , Overland James
Published: October 2023

The Arctic is warming twice as fast as the global mean, making Arctic research essential for understanding the global climate system. For 50 years, researchers at the NOAA Pacific Marine Environmental Laboratory have sought to detect and understand the numerous changes the Arctic is undergoing, the Arctic’s connections with the Earth system, and the impacts of climate change on the people who live in the Arctic. PMEL accomplishments in Arctic research include identifying future states and variability of sea ice, defining the ice-free Arctic threshold and initiating a climate model selection process by applying observational constraints, developing a Bering Sea conveyor belt sea ice model and a vessel spray-icing index, investigating internal versus forced response of Arctic temperature change, connecting the Arctic with mid-latitude weather, and rescuing historical data. Through continued study, improved understanding, and communication, PMEL research informs policymakers, managers, and the public to help ensure a sustainable future for the Arctic.
Introduction
Authors:   NOAA PMEL, Feely Richard
Published: October 2023

In October 2023, we will celebrate the 50th anniversary of NOAA’s Pacific Marine Environmental Laboratory (PMEL), a world leader in oceanographic research and the development of innovative instrumentation and measurement strategies for monitoring and observing ocean conditions at global scales. Through the collective efforts of PMEL and its national and international research partners, our researchers have fundamentally advanced the scientific understanding of climate variability and change, extreme and weather events, the effects of climate change on marine ecosystems, ocean carbon and sulfur cycles, ocean acidification, Arctic oceanography, tsunamis, and ocean-seafloor interactive processes. During this same period, PMEL scientists and technicians have been advancing the science and technology innovation necessary to expand our observational capabilities in order to provide coverage over large sections of the ocean. These advances have profoundly shaped our understanding of Earth system processes and have led to improvements in environmental prediction, climate assessments, and weather and climate services.

The Pacific Marine Environmental Laboratory (PMEL) conducts global and regional oceanographic research in support of the National Oceanic and Atmospheric Administration’s (NOAA’s) three mission areas: (1) understanding and predicting changes in climate, weather, oceans, and coasts; (2) sharing that knowledge with others; and (3) conserving and managing coastal and marine ecosystems and resources. Since its establishment in 1973, PMEL’s work has ranged from pole to pole and across the global ocean. The lab’s research has examined ocean structure and function in the physical, chemical, and biological realms, and has informed and supported the development of US policy in these areas.
Significados, experiencias y reflexiones acerca de competencias didácticas de estudiantes normalistas
Authors: Martínez Alcalá Gloria
Published: October 2023

El reto de la educación normal en México es formar de manera integral maestros de educación básica capaces de afrontar las demandas de la sociedad. Por consiguiente, se integra este estudio para comprender el proceso de desarrollo de las competencias didácticas que experimentan profesores en formación de II semestre de la Escuela Normal del Valle de Mexicali, al cursar la asignatura de Planeación y Evaluación. Para ello, se utiliza el paradigma cualitativo, con una aproximación fenomenológica y etnográfica con el fin de lograr la interpretación del sentido que éstos le otorgan a sus experiencias y reflexiones sobre la práctica, para la profunda comprensión del proceso de apropiación de las competencias didácticas, en las dimensiones conceptual, procedimental y actitudinal. La información fue recabada mediante entrevista grupal, observación participante y registro anecdótico. Los hallazgos delinean la subjetividad en el proceso de desarrollo de las competencias didácticas durante el curso; ya que a pesar de tener una significación positiva de ser docente ésta se basa únicamente en el aspecto actitudinal de la competencia; dejando de lado los aspectos conceptuales y procedimentales -el saber hacer- que requiere la formación docente e incluye los conocimientos teóricos y metodológicos para la enseñanza. Por tanto, se señalan posibles rutas de acción encaminadas a favorecer aprendizajes considerando las emociones y experiencias de quienes viven el proceso formativo.

Authors: P KADIRVEL  , PRADUMAN YADAV  , N MUKTA
Published: October 2023

Improvement of oil content and quality are important goals in safflower breeding. In this study, a set of 10 high oil exotic safflower cultivars were evaluated at Hyderabad (India) for oil content and fatty acid composition in order to assess their suitability for Indian safflower breeding programmes. Oil content in the exotic varieties ranged from 35.3 per cent (Finch) to 41.4 per cent (Centennial). Overall, the exotic varieties showed about 5 to 10 per cent increase in oil content over the most popular Indian high seed yielding varieties A-1 and Bhima. Furthermore, six varieties showed high oleic acid content ranging from 70.0 per cent to 80.2 per cent. The exotic varietal sources reported in this study would be helpful to expedite breeding high oil-high oleic safflower cultivars in India.
Interspecific hybrid between silver leaf sunflower (Helianthus argophyllus T. and G.) and cultivated sunflower: Cytomorphological characterization of F1 hybrid
Authors: H P MEENA  , H D PUSHPA  , M SUJATHA
Published: October 2023

Hybrid plants were obtained by crossing cultivated sunflower (Helianthus annuus L., 2n=2x=34) lineARM-243B and a wild Helianthus species [H. argophyllus; 2n=2x=34; HEL-153/83 (PI-649865)], using the latter as pollen parent. The wild Helianthus accession was selected for this study because of its short duration and short plant height compared to other accessions of H. argophyllus. Morphological and cytological analyses were carried out to confirm the hybrid nature of the F1 plants. The hybrids exhibited morphological features intermediate to both the parents for few attributes and more related to wild Helianthus species like leaf and stem pubescence, stem hairiness, flower colour, stem size, branching, disc floret pigmentation, plant height, seed size and seed shape etc. A reduction in pollen fertility (87.5%) was recorded in F1 plants as compared to both the parents. Meiotic analysis revealed a mixture of univalents, bivalents, trivalents and quadrivalents in all the pollen mother cells (PMCs) analysed. In addition to bivalents and univalents, a trivalent was also observed in few PMCs, indicating segmental homology between chromosomes. Frequently observed chromosome configurations in diakinensis were 15 II + 1 IV and 13 II + 2 IV. The results suggested that the species H. argophyllus and H. annuus differ by 1-2 translocations and 1-2 inversions. Results show that the wild species is compatible with cultivated sunflower and using H. argophyllus cultivated sunflower can be improved for biotic (downy mildew) and abiotic stresses (drought and salinity).
Oilseeds production and yield forecasting using ARIMA-ANN modelling
Authors: S RAVICHANDRAN  , B S YASHAVANTH  , K KAREEMULLA
Published: October 2023

Agriculture, the backbone of Indian economy, lot of time series data on various parameters and these time series data generated from agriculture can be effectively modelled using various time-series modelling techniques such as Box-Jenkins ARIMA modelling technique, State-Space modelling technique, Structural Time Series modelling methodology and various other time series modelling methodologies depending upon the availability and properties of the given datasets. Modelling and forecasting of time-series data on all-India production and productivity of nine oilseed crops from 1950-51 to 2015-16 is carried out in this study. Modelling and subsequent forecasting for the datasets under consideration is performed using Autoregressive Moving Average (ARIMA), Artificial Neural Network (ANN) and ARIMA-ANN hybrid modelling methodologies. It is important to note that ARIMA is a linear modelling methodology whereas ANN is a non-linear modelling methodology. ARIMA-ANN is a hybrid of these two methodologies which can efficiently capture both linear and non-linear structures present in the dataset under consideration. For efficient performance of ARIMA modelling, the data under consideration needs to satisfy stationarity criterion. i.e. mean and variance should constant over a period of time. First, the dataset on oilseeds production and productivity are tested for stationarity and subsequent to non-stationarity of the original data, firstorder differenced series are considered for modeling using the Box-Jenkins approach. Various ARIMA models are developed and among them ARIMA (1,1,0) and ARIMA (1,1,1) are found suitable for the production andproductivity data, respectively, based on the Information Criteria such as Akaike Information Criterion (AIC) and Schwarz-Bayesian Criterion (SBC). Among the developed ANN models, the Neural Network Autoregression(NNAR) of order NNAR (2,2) is found to be suitable for both the variables under study. Later, models using ANN-ARIMA hybrid methodology are developed and the ARIMA (1,1,0)-NNAR(1,1) and ARIMA (1,1,1)-NNAR(1,1) for production and productivity are found to be suitable, respectively. All the three models are tested for their forecast accuracy using Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). Accordingly, the ARIMA-ANN hybrid methodology is found to be superior to the individual ARIMA and ANN methodologies. Based on the efficient developed model viz., hybrid ARIMA-ANN model, forecasting annual all-India oilseeds production for the year 2022 is carried out and is found to be 35.6 (±3.2) million tonnes with a productivity of 1178 (±94.6) kg/hectare.

Published: October 2023

A field experiment was conducted to study the effect of sequntial application of pre-and post-emergence herbicides on growth, nutrient uptake and yield of broadcast sesame on sandy loam soils. Eleven weed management practices consisting of pre-emergence application of pendimethalin @ 750 g/ha, oxyfluorfen @ 75g/ha and oxadiargyl @ 75g/ha alone and sequential application ofthese pre-emergence herbicides followed by post-emergence application of quizalofop @ 50g/ha and propaquizafop @ 60g/ha including two hand weedings at 20 and 40 DAS and unweeded check were compared in randomized block design with three replications. Results revealed that the lowest density and dry weight ofweeds with lesser weed index were recorded in the plots treated with pre-emergence application of oxyfluorfen @ 75g/ha followed by quizalofop @ 50 g/ha applied at 20 DAS. The same weed management practice recorded significantly higher stature of growth parameters and yield attributes. The increase in seed yield of sesame was 38.0 per cent with sequential application of oxyfluorfen @ 75g/ha followed by quizalofop @ 50 g/ha applied at 20 DAS compared to unweeded check. Heavy weed infestation in unweeded check plots resulted in incresed weed nutrient uptake upto 44.6, 5.6 and 34.0 kg of N, P and K/ha, respectively. Oxadiargyl and oxyfluorfen @ 75 g/ha each showed phytotoxicity score of '4' and '3' respectively in 0 to 10 scale. Pre-emergence application of oxyfluorfen @ 75 g/ha followed by propaquizafop @ 60g/ha applied at 20 DAS recorded the highest benefit-cost ratio.
A simple and rapid method for isolation of DNA for molecular markers and transgene analysis in safflower
Authors: BISHUN DEO PRASAD  , SANGITA SAHNI  , PANKAJ KUMAR
Published: October 2023

In spite of the possibility of analysing large samples and the rapidity of Polymerase Chain Reaction (PCR) technology, the usual protocols for DNA plant extraction remain time-consuming, slow and involves use of hazardous chemicals. To lessen labor, time or cost of DNA extraction, a simple and instant method for genomic DNA extraction from leaf tissue of safflower (Carthamus tinctorius L.) leaf is established. Small quantity of tissue material (typically3-5mg) was ground in a centrifuge tube using plastic pestle in extraction solution. ExtractedDNA was suitable for PCR analysis, without centrifugation. The feasibility of this method was confirmed by testing molecular markers and transgene detection. This method requires less than 1 mg of plant tissue stored frozen or used fresh and is useful for molecular marker analyses as well as transgene detection.

Published: October 2023

Five sunflower hybrids and a variety were evaluated in four different centres of North Eastern Hill (NEH) regionsto study their suitability in terms of growth, yield and oil content to tap the potential rice fallow areas in NEH regions (Jharnapani, Medziphema, Tadong, and Lembucherra). Uniform layout was adopted at four locations to conduct field trials with RBD design. The soils of the region except Lembucherra were found to be acidic (ranged between 4.6 and 5.7 pH) and therefore requires regular lime application for obtaining high seed yields ofsunflower. The location Tadong was on high altitude (1300 m MSL) and recorded less number of average sunshine hours (2.5hours/day) during the sunflower crop period was responsible for lanky growth of sunflower with low oil content. However, Lembucherra was highly suitable for growing sunflower as weather conditions were highly favourable. Further, assessment of various growth and yield parameters it was found that average yield ofsunflower in Tadong location was the highest (1814 kg/ha) but had low average oil content (28.6%) and attained average maturity in 135 days. While Lembucherra centre recorded seed yield of 1532 kg/ha with average oil content of 37.1 per cent and found to complete crop cycle at the earliest over other centres by attaining maturity on an average in 113 days. Among all the hybrids, DRSH-1 showed highest oil content in all the locations and mean value across the centres was 39.6 per cent.

Published: October 2023

A field experiment was conducted to evaluate the efficacy of newer insecticides against whitefly in castor during kharif season 2016 and 2017 at Tapioca andCastor Research Station,Tamil Nadu Agricultural University, Yethapur, Tamil Nadu. Based on whiteflies number/3 leaves/plant and per cent reduction over control recorded after two sprays concluded that all the treatments showed significant difference in reducing whiteflies over control. Among the insecticides, buprofezin 25 SC @ 0.8ml/l was found significantly most effective followed by profenophos 50 EC @ 2ml/l, imidacloprid 17.8 SL@0.5ml/l, dimethoate 30 EC @ 1.7ml/l and flonicamid 50 WG@0.2g/l for reducing the whiteflies population. Highest seed yield was obtained with buprofezin 25 SC @ 0.8 ml/l (2034 kg/ha) followed by flonicamid 50 WG @ 0.2g/l (1723 kg/ha) as against 694 kg/ha in untreated control. The maximum incremental cost-benefit ratio of 1: 16.74 was obtained with application of buprofezin 25 SC @ 0.8 ml/l.

Published: October 2023

Three cross combinations were attempted by using Pusa Gold, YST-151, Ragni and NDYS-425 cultivars of yellow sarson as parents. Parents were selected on the basis of variability for days to maturity, seed yield, oil contentand other agronomic traits. Six generations (P1, P2, F1, F2, BC1, BC2) in each cross (Pusa Gold x YST-151, Ragni x NDYS-425 andRagni x YST-151) were evaluated in a compact family block design with three replications during 2011-12 cropping season. Data were recorded for several morpho-physiological traits like seed yield per plant, plant height, primary branches per plant, Daysto 50% flowering, length of fruiting zone, siliqua per plant, siliqua length, days of maturity, 1000-seed weight and oil content. Analysis of variance for six generations revealed significant differences among the progenies (generations) within family (cross) for most ofthe evaluated traits except for siliqua length and days to maturity. The differences were highly significant (p#0.001) for length of fruiting zone and seed yield per plant. For the traits primary branches per plant, siliqua per plant and seed yield per plant, the performance of hybrids was superior to their respective parents in all crosses studied. Six parameter model (m, d, h, i, j, l) and scaling tests revealed the presence of inter-allelic interactions (epistasis) for most of evaluated traits except days to maturity in Pusa Gold x YST-151cross and indicated the inadequacy of additive-dominance model. The prime objective of current study was to estimate gene effects controlling yield and its related attributes by generation mean analysis and scaling test.

The Front Line Demonstrations (FLDs) on modern approaches of sunflower cultivation was attempted during rabi season 2011-12 to 2013-14 on farmers' field in the non-traditional belts of West Bengal (Bankura and Purulia districts) under Tribal Sub-Plan Programme. The average seed yield of sunflower under demonstration plot was recorded 1875-2250 kg/ha compared to conventional rapeseed mustard cultivation where production was recorded 1000-1200 kg/ha. In West Bengal, the yield gaps between improved technology (full package of sunflower demonstration with best management practices) and farmers practice (rapeseed mustard cultivation through conventional approaches) was recorded 875-1050 kg/ha. The study recommends that the gross return and net return can be improved by adopting technologies viz., use of sunflower hybrids (DRSH-1, KBSH-44, KBSH-41, KBSH-53), adopting proper spacing and thinning, spraying of boron at ray floret stage and use of bio-inoculants for management of diseases.
Doubling farmers' income : Scenario, challenges, opportunities and the way forward
Authors: V RANGA RAO
Published: October 2023

The country's farm sector, the lifeline of economy, has been of late in the throes of a very paradoxical situation namely its shrinking share in country's GDP amidst dependence of close to 60% of country's population on it fortheir livelihood worsening the agrarian distress and the associated high farmer suicides every year in the face of spectacular performance on the production and productivity front in the form of 'green', 'blue' 'yellow' 'white' revolutions. The average income ofmore than 60% offarm households in the country with less than one hectare land is hardly a fourth of the current national average per capita income. While no doubt, the farm sector today offers a plethora of avenues for stepping up aggregate production as well as productivity of agri-horti, animal, fish, bird per unit area, input, time and effort, banishing current agrarian distress coupled with doubling farmers' incomes may however, continue to be a vision in spite of all such isolated and fragmented efforts. The paper therefore, calls for an integrated multi-pronged, multi-dimensional initiativesinvolving production as well as post production chain for translating not only PM's vision into reality at ground level but liberate the much distressed sections of the farm sector, i.e. the millions ofsmall and marginal farmers of the society fromtheir chronic vulnerabilities to weather and market risks, poverty, indebtedness, structural inefficiencies, adverse terms of trade, anti-farmer farm policies, rampant supplies of spurious and substandard inputs and thru it transform their lives and economies.

Published: October 2023

Sesame (Sesamum indicum L.) is one of the most ancient oilseed crops. This important annual oil seed crop has been cultivated widely for its edible oil (42-54%) and protein (22-25%). Sesame oil has two important components, sesamin and sesaminol, which play a major role in antioxidant activity. Seed pelleting is an effective, simple technique to enhance crop establishment under unfavourable environmental conditions, particularly in the case of small seeded crops like sesame. The role of rhizosphere population is important in the context of providing conducive environment and enhancing the yield of the growing plants. Fly ash is a coal combustion residue of thermal power plants. It has great potentiality in agriculture due to its efficacy in modification ofsoil health and crop performance. The high concentration of elements (K, Na, Zn, Ca, Mg and Fe) present in flyash increases the yield of many agricultural crops. The role of flyash in influencing microbial activity through increased microbial population was studied in sesame through seed pelleting technique. Field experiments were conducted with flyash @ 200, 250 and 300 g with rice gruel and gum arabic (as adhesives) to study its influence on crop growth, soil parameters and microbial population in sesame. The experimental results revealed that seed pelleting with fly ash increased crop growth, soil parameters and microbial populations of bacteria, fungi, Actinomyctes, rhizobium, Azospirillum and seed yield in sesame, when compared to other treatments.

Groundnut and sesamum are two important oilseed crops grown in Andhra Pradesh. Adoption gaps were identified in both the crops indicating the need for demonstration of improved crop management practices. In groundnut, the varietyKadiri 7 bold was demonstrated in kharif and rabi seasons while in sesamum, the varietyYLM 66 was used for demonstration during summer. Along with the varietal introduction the whole package of improved management practices were also demonstrated. A total of 40 FLDs each in groundnut and sesamum were organized for two consecutive years 2016-17 and 2017-18 in Krishna district, Andhra Pradesh. In kharif groundnut, highestyield of 41.75 q/ha was recorded in the demonstration fields with an average yield of 36.95 q/ha while in rabi groundnut, the highest yield of 41.63 q/ha was recorded in demonstration plot with an average yield of 40.77 q/haas against farmers practice of growing local varieties gave an average yield of 30.00 q/ha in both the seasons. In sesamum, highest yield of 15.20 q/ha was recorded in the demonstration fields with an average yield of 15.00 q/haas against farmers practice of growing local varieties gave an average yield of 10.40 q/ha. Paired t test of the economics of demonstrations and farmers practices showed significant and positive difference between improvedpractice and farmers practice.

Authors: BABITA KUMARI  , S R KUMHAR
Published: October 2023

Genetic variability and divergence were studied in 40 genotypes/varieties of sesame for eleven yield and yield related traits. Analysis of variance exhibited significant differences for all the characters suggesting the presence oflarge amount of inherent genetic variability among the genotypes studied. The maximum magnitudes of phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) were observed for number of primarybranches per plant, number of capsules per plant and capsule bearing length (cm). Estimates of heritability was high for number of primary branches per plant, days to 50% flowering and seed yield, days to maturity, and highheritability coupled with high genetic advance as 5% of mean was observed for number of primary branches per plant and seed yield per plant suggesting additive gene action for expression of these characters. The hierarchical cluster analysis indicated the presence of considerable genetic divergence among the genotypes/varieties. The genotypes were grouped into seven clusters using Ward's minimum variance method. The inter-cluster Euclidean2 distance was maximum between cluster-III and VII (68.33) followed by cluster-IV and VII (61.40) and cluster-II and VII (59.59) which indicated that the genotypes included in these clusters could give high heterotic response and thus better segregants. The maximum cluster means were revealed by cluster-II for number of capsules per plant, capsule bearing length and seed yield per plant followed by cluster VII for number of primary branches per plant and 1000 seed weight, and cluster-VI for number of seeds per capsule. Based on this observation, it could be concluded that genotypes carefully chosen from clusters II, VI and VII, would offer a better scope of improvement of sesame through recombination breeding.

Safflower (Carthamus tinctorius L.) is one of the most important traditional rabi oilseed crops grown in India. Safflower aphid, Uroleucon compositae (Theobald) is the key pest which causes yield losses to the extent of 30 to 78 per cent if not managed properly. Use of resistant varieties is one of the important components of IPM in safflower as the crop is mainly grown under resources poor conditions. The experiments were conducted during rabi,2018-2019 at ICRISAT Farm, ICAR- IIOR, Hyderabad to evaluate 50 safflower germplasm accessions and 20 varieties for their reaction to aphids under artificial infestation. Test entries were infested with aphids artificially bytransferring infested plants froman infester block raised separately. The reaction was recorded and categorized based on Aphid Infestation Index (AII) on 1.0 to 5.0 scale. Ten germplasm accessions, viz. GMU-671, GMU-599,GMU-3256, GMU-5133, GMU-5848, GMU-7868, GMU-7869, GMU-7870, GMU-7885, GMU-7917 were found moderately resistant to aphids with an average AII ranging from 2.3- 3.0. Out of 21 varieties evaluated, one variety,Girna was found resistant with an average AII of 2.0. Seven varieties viz. SSF-748, Bhima, A-1, SSF-708, PBNS-12, SSF-733 and Manjira were found moderately resistant to aphids with an average AII ranging from 2.3 to 3.0.

Soybean [Glycine max (L.) Merr.] is a major oilseed crop of India. Seed weight is an important yield component trait which should be suitably optimized in soybean varieties to maximize productivity. To validate 100-seed weightquantitave trait loci (QTL), a backcross population of soybean was developed from a cross between wild species Glycine soja (Sieb. and Zucc.) and Indian soybean cultivar JS 335. The BC2 backcross population was evaluated for three yield component traits, namely 100-seed weight, number of seeds/plant and seed yield/plant in BC2F2, BC2F3 and BC2F4 generation. Six QTLs reported to be associated with 100-seed weight in soybean were selected for QTL validation. SSR markers linked with two major QTLs for 100-seed weight could be validated successfully. One QTL, on linkage group D1a between Satt580-Satt179, identified for 100-seed weight explained 19.18% ofphenotypic variance for combined data of three years. The second QTL for 100-seed weight was identified on linkage group C2 between marker Sat_251 and Sat_238 which contributed 10.97 and 9.28% of phenotypic variance in year 2015 and 2016, respectively.

The present investigation was carried out to study stability performance for seed yield and its components in 24 soybean varieties using a randomized complete block design. The partitioning of (environment + genotype x environment) mean squares showed that environments (linear) differed significantly for yield and its component characters except for 100-seed weight. Stable genotypes were identified for wider environments and specific environments with high per se performance (over population mean) for seed yield/ha. The investigation revealed that the genotype AMS 243 and DSB 20 possessed desirable stability across the environments. Genotypes AMS MB 5-19, NRC 2007 2-19 were suitable for favourable situations for seed yield.

For standardization of water and nutrient requirements of oil palm field experimentation is essential. In order to get accurate results from the field experimentation, optimal plot size is very important. Not much work has been done on these lines to find out the optimum size of the plot for field experimentation in oil palm. In the present study, two statistical methods were employed and compared to find out the optimal plot size for conducting field experiments in oil palm under Indian conditions using 6 years yield data from ICAR-Indian Institute of Oil palm Research. Oil palm yield is measured in FFBs (fresh fruit bunches) and the FFB number and yield data of individual palms was collected from 10 different cross combinations having three replications and 270 palms. Two statistical procedures were employed on these data viz., Mean Square Error (MSE) and Maximum curvature method. From both these methods, 7 palms per plot were found to be the optimum size in oil palm for field experiments. As both MSE and maximum curvature of coefficient of variation methods have given same result, if secondary data is available for any other tree crops, one of these two methods can be employed for finding out the optimum plot size.

The present study was taken up to work out correlation coefficient among the various yield and yield related traits and to estimate direct and indirect effect of different traits on grain yield through path analysis in linseed. Fortydiverse linseed genotypes were assessed for different traits in a field experiment. Correlation as well as path coefficient analysis were calculated among the traits. Association analysis revealed that seed yield/plant showed the highest and significant positive association with biological yield/plant, number of capsules/plant, harvest index, 1000-seed weight and number ofsecondary branches/plant. Path coefficient analyses, at genotypic and phenotypic level, indicated the significant direct and indirect effects of the traits on yield.

Field studies were conducted to evaluate the efficacy ofselected fungitoxicants viz., mancozeb 75 WP @ 0.2%, metalaxyl 8%+ mancozeb 64% @ 0.2%, hexaconazole 5 EC @ 0.05%, cymoxanil 8% + mancozeb 64% @ 0.1%and azoxystrobin 23% SC 0.05% as a single spray treatment at 45 DAS and each four fungicides at 60 DAS in succession of mancozeb 75 WP at 45 DAS in control of white rust disease. The experiment was carried out for twoconsecutive years during rabi 2014-15 and 2015-16 with susceptible Indian mustard cultivar Varuna. All the fungicides tested were significantly effective in reducing the disease over the check; however the level of efficacy varied among the treatments. The plots sprayed with mancozeb (0.2%) at 45 DAS followed by azoxystrobin (0.05%) at 60 DAS recorded significantly lower disease severity over the other treatments both at leaf and staghead phasewith significant highest seed yield of 1906.81 kg/ha which was 42.33% higher over the check. The spray of mancozeb (0.2%) at 45 DAS followed by metalaxyl + mancozeb (0.2%) at 60 DAS was the next best treatment among combinations of two fungicidal sprays. Among single fungicidal spray treatments, spray of metalaxyl + mancozeb @ 0.2% was effective in reducing white rust at leaf and staghead phases with concomitant increase in seedyield. In general, none of the single spray treatments was found superior over the plots that received two fungicidal sprays i.e. mancozeb at 45 DAS followed by other fungicides at 60 DAS.
