Психологические факторы обращения мужчин за профессиональной психологической помощью
Authors: Шаповалов Роман
Published: March 2022

Мировая психология накопила огромное количество социально-психологических исследований обращения мужчин за профессиональной психологической помощью (ППП), однако все еще наблюдается дефицит работ в области психологии личности. В исследовании психологических факторов обращения мужчин за ППП приняли участие 156 мужчин (возраст Mean = 33,72; SD = 10,49) и 171 женщина (возраст Mean = 32,33; SD = 10,51), итого 327 человек (возраст Mean = 32,99; SD = 10,51). Методики исследования: личностный опросник «Большая пятерка–2» (Big Five Inventory – 2) в адаптации Щебетенко с соавторами; переведенная автором шкала Фишера и Тернера по исследованию отношения к обращению за ППП. Непараметрический критерий для независимых выборок H Краскелла–Уоллиса с поправкой на множественные сравнения тестом Данна (post hoc Dunn’s test) показал, что за ППП обращаются мужчины с менее выраженной Энергичностью (p = 0,019), с более выраженной Негативной эмоциональностью (p = 0,007), Тревожностью (p = 0,038), Депрессивностью (p = 0,004), Открытостью опыту (p = 0,009), Любознательностью (p = 0,003), а также с более позитивным отношением к обращению за ППП (p < 0,001). Для остальных черт личности и их фасетов значимых различий не обнаружено. Данные результаты позволяют предположить, что большая или меньшая выраженность черт личности и их аспектов может выступать в качестве специфических психотерапевтических запросов. Для будущих исследований рекомендовано увеличение подвыборок обращавшихся и не обращавшихся за ППП мужчин и женщин, а также включение в исследование вопросов об удовлетворенности и результативности обращения за ППП для получения более подробных результатов об опыте обращения за ППП.
Gender dalam Pandangan Islam

Published: March 2022

Penelitian ini mencoba membandingkan konsep kesetaraan gender yang diusung oleh feminisme dengan keadilan Islam. Metode penelitian yang digunakan adalah studi kepustakaan (library research) dengan menggunakan pendekatan kualitatif. Hasil penelitian menunjukan banyaknya dokumen hukum dan bagian yang mengatur hubungan antara laki-laki dan perempuan dalam Islam telah diubah untuk menyamakan perspektif kesetaraan gender. Namun problematikanya banyak konsep kesetaraan yang tidak sesuai dengan gagasan keadilan. Pertama, titik tekanan. Fokus dalam kesetaraan gender adalah persamaan kuantitas sehingga mengabaikan perbedaan antara laki-laki dan perempuan. Sementara dibenarkan kebutuhan setiap individu terpenuhi sesuai dengan atribut dan kemampuan. Kedua, orientasi. Kesetaraan gender berusaha untuk meruntuhkan budaya patriarki dan menuntut kesetaraan dan kebebasan. Peradilan di sisi lain berusaha untuk menyelaraskan budaya patriarki dan matriarkat sehingga laki-laki dan perempuan dapat bertindak sebagai khalifah. Ketiga, pandangan perempuan. Feminisme memandang laki-laki dan perempuan sebagai dua makhluk yang berbeda. Sedangkan Islam di sisi lain menganggap pria dan wanita sebagai sepasang dua entitas, mereka memiliki hak dan kewajiban yang sama namun memiliki fungsi yang berbeda tergantung pada sifat masing-masing. Berdasarkan hal tersebut, konsep kesetaraan tidak dapat disamakan dengan keadilan dalam Islam.

Application of crop simulation models at larger spatial scales is very essential to develop best management practices in order to maximize yields and reduce environmental pollution. In the present study, spatial analysis of long- term simulations were carried out with DSSAT spatial analysis tool linked with GIS to estimate irrigation requirements and nitrate leaching under alternate rice establishment methods in the Wargal watershed, Andhra Pradesh, India. Rice yields were compared among three management scenarios: rainfed, aerobic and flooded systems. Grain yield, seasonal water balance components, nitrate leaching and water use efficiency were calculated, visualized and mapped with GIS. The rice productivity increased by 22% and 27% under aerobic and flooded management compared to rainfed rice. The adoption of new water efficient aerobic rice cultivation in the watershed resulted in 36% water saving with a relatively small yield reduction of 4%, thus increasing the water productivity to 0.77 g kg-1 in aerobic compared to 0.56 g kg-1 in flooded rice. The aerobic rice method reduced the overall water pumping hours to 88 h ha-1 during rice crop season compared to 299 h ha-1 with flooded rice cultivation, resulting in 71% energy savings.

Published: March 2022

Nitrogen stress sensors are based on reflectance measurement controlled by the chlorophyll content. Reflectance of canopy is spectral dependent and more sensitive narrow spectral band can be exploited for reflectance measurement sensors.The experiments for present study were conducted in split plot design on two widely grown wheat (Triticumaestivum L.) cultivars (GW 496 and LOK 1) during rabi seasons of three consecutive years 2007-08 to 2009-10 at Anand. The two cultivars viz; GW 496 and LOK 1 were taken as the main treatments and five nitrogen fertilizer application rates 120, 90, 60, 30 and 0 kg N ha-1 as sub-treatments were randomized in four replications. Spectral reflectance measurements were taken over wheat canopy at different crop growth stages with a dual channel spectroradiometer.The ratio based and soil based indices (viz; RVI, DVI, NRI, RDVI, OSAVI,SAVI2,TSAVI and PVI) were used tofind optimal wavebands.The optimum wavebands were explored using contours of R2 values of all possible two band combination for each vegetation index on 2D matrix plots. Except PVI, all indices revealed that red edge inflection point at 733-736 nm was the most sensitive to nitrogen status. The sensitivity of red edge inflection point also explored with first derivatives.

The regional climate models provide sufficient information of the climate data, which can be used for simulating the impact of expected climate change on crop growth and hydrological processes. But future climate data derived from such models often suffers from bias and is not ready to use per se in crop growth/hydrological models, wherein reasonable and consistent meteorological daily input data is a crucial factor. The present study concerns the assessment and minimization of the bias in the PRECIS modeled data of maximum and minimum temperatures and rainfall for Ludhiana station, representing central Punjab of India. The correction functions for three corrective methods i.e. difference, modified difference and statistical bias correction at daily, monthly and annual time scales were developed and validated to minimize the bias. Amongst these, correction functions derived using modified difference method at daily time scale for rainfall and at monthly time scale for Tmax and Tmin were found to be the superseding.

Published: March 2022

Nondestructive and fast chlorophyll assessment can be made with portable chlorophyll meters. The meters measure the transmittance of red and near infrared radiation through the leaf and estimates the chlorophyll in non-dimensional index values by defined arithmetic operations.These metes required to calibrate for conversion of index values to the actual chlorophyll content in desired units. Calibration of widely used TYS-A (SPAD meter) and CCM-200 (Chlorophyll content index (CCI) meter) chlorophyll meters wasattempted for chlorophyll estimation in bread wheat (Triticum aestivum L.) leaves.The chlorophyll values for the wheat leaves were measured with chlorophyll meters and same samples were used in standard photometric measurements in laboratory. The SPAD values showed statistically significant linear relationship with chlorophyll content (R2=0.92). The functional relationships represented with regression models can be used to convert the SPAD value to actual chlorophyll content for wheat. The relation between SPAD and CCI was studied using independent leaf samples (n=159). The relationship was found curvilinear and fitted with statistically significant quadratic polynomial (R2=0.86).So, the fitted quadratic model can be used for inter-conversion between SPAD and CCI. The model was used to convert the values from SPAD to CCI. The derived CCI values were used to fit establish the relationship between CCI and actual chlorophyll content of wheat.

Identifying the suitable sites for insitu and ex-situ soil and water conservation interventions with the help of survey is one of the giant tasks for planners. Considering the time consumption for conventional geographical surveys for identification of potential sites, a methodology is being developed using the remote sensing and GIS techniques to find the suitable locations for different insitu soil and water conservation interventions. Different thematic layers of slope, soil, rainfall and land use land cover was intersected in ARCGIS and the selected criteria for each intervention was applied for identifying the suitable locations. This methodology was applied for identifying the suitable locations of different insitu soil and water conservation interventions such as contour bunds, semi-circular bunds, small pits, contour bench terraces, contour ridges and stone bunds in Adilabad District of Telangana state. Among the different interventions selected, stone bunds, contour bunds and small pits are more suitable for major portion of the Adilabad District. This methodology deciphers more precise, easier and less time consuming planning technique which has the ability to process districts or even large catchments.

Published: March 2022

The impact of projected climate during 2020-2080 on the potential yield of potato in Bihar has been analysed using InfoCrop model. Data from field experiments conducted at Patna, with popular potato variety Kufri Ashoka grown in rabi season of 2008-09 through 2010-11, was used for calibration and validation of model. It is indicated that increased minimum and maximum temperature projected for future time periods, however, almost no change in rainfall is projected for the stations under studied. The crop planted on 2nd December, showed projected decline in yield ranging from 3.3-5.9% for 2020, 12.5-15% for 2050 and 19.3-24.8% for 2080 time period across the locations studied. Delayed planting by 10 days successively from 2nd December through 22nd December showed a progressively lower decline in the projected yield at different locations. However, advancing the planting time by 10 days resulted inhigher decline in projected yield. Weather data analysis performed for the crop season (November-February).

The sensitivity analysis of three T. aesivum (GW 322, GW 496 and GW 366) and one T. durum (GW 1139) cultivar of wheat was performed to see the possible change in the grain yield of wheat due to changed sunshine hours (BSS), maximum and minimum temperatures using WOFOST model. The potential condition was assumed with congenial weather and adequate management practices. The results showed that the increase in sunshine hours was found to increase the yield in all cultivars and vice versa. The rise in maximum and minimum temperatures had adverse effect on wheat yield. The increase in the maximum temperature by 5°C may cause reduction in yield by 24 to 29%. The effect of the minimum temperature was also of the similar order, but the varietal differences were observed. Among the cultivars, GW 496 was found to be most sensitive to maximum temperature and less to bright sunshine hours. Among the different stages, flowering to dough stage was found to be most sensitive stage.

The experiment comprising of four tillage methods viz., puddling (PTR), conventional tillage without puddling (CT), reduced tillage (RT) and zero tillage (ZT) and four nitrogen levels at 0, 100, 125 and 150 kg ha-1 was conducted in a strip plot design with four replications at Punjab Agricultural University, Ludhiana during 2010 and 2011 to study the effect of tillage and nitrogen levels on productivity and heat utilization in mechanically transplanted rice. Results revealed that periodic plant height and dry matter accumulation by the crop recorded at 30, 60, 90 DAT and at harvest, leaf area index (LAI) and photosynthetically active radiation (PAR) interception by the crop at panicle emergence stage and the grain yield were statistically at par in mechanical transplanting in CT and PTR but significantly higherthan that in RT and ZT. Application of 150 kg N ha-1 recorded significantly higher LAI, PAR interception, number of tillers and grain yield than that in 0, 100 and 125 kg N ha-1. Mechanical transplanting in CT recorded highest accumulation of growing degree days (GDD) and highest heat use efficiency (HUE). The accumulated GDD and HUE increased significantly with each successive increase in nitrogen dose from 0 to 150 kg ha-1.

Field experiment was conducted during 2012 and 2013 to study yield variations in rice genotypes (Oryza sativa L.) due to leaf colour chart (LCC) based N application and agrometeorological indices. Treatments included two rice genotypes (Jhelum and SR-2) and eight rates of N application (control, recommended practice (120 kg N ha-1) and LCC d” 3, 4 and 5 @ 20 and 30 kg N ha-1) laid out in randomized block design replicated three. The pooled data showed that SR-2 recorded significantly higher value of yield and growing degree days (GDD), heliothermal units (HTU) and heat use efficiency (HUE), besides took more days to reach different phenophases as compared to Jhelum. LCC d”5 @ 30 and 20 kg N ha-1 recorded significantly higher grain yield, GDD, HTU, HUE and took maximum number of days to different phenophases. This indicated that N application based on LCC 5 should be adopted in rice cultivars particularly SR-2 to achieve maximum yield under temperate conditions of Kashmir valley.

Authors: RASHMI MEHTA  , VYAS PANDEY
Published: March 2022

The reference evapotranspiration (ETo) is an important agrometeorological parameter which has been used in a number of applications. In present study daily ETo was determined for 16 stations of Gujarat having long period (10-20 years) weather data following P-M approach. The Kc values for maize and wheat as given in FAO-56 was used in which Kcmid and Kcend were corrected for climatic conditions of stations. The corrected Kc values were used to calculate the daily crop water requirement (ETc) for wheat and rabi maize crops grown at different locations of Gujarat. The results revealed that during winter season (Nov. 15 to March 13) the mean daily (ETo) varies from 4.2 to 7.6 mm day-1. However the large variation in ETo across the locations (2.9 to 9.8 mm day-1) was observed, the lowest being at Khedbrahma and highest being at Targadia. The correction applied in Kcmid and Kcend suggested that at most of the stations Kcmid and Kcend for wheat crop were higher than that of FAO values while the corrected Kc values for maize were found to be less than that given by FAO. The mean water requirement (ETc) of wheat during its initial stage was found to be lower and almost constant and it increased continuously during developmental stage (from 1.9 to 5.2 mm day-1) and during the mid season stage (from 5.6 to 7.5 mm day-1) and decreased during the late-season stage (from 7.3 to 3.6 mm day-1). The seasonal water requirement across the locations varies between 400.5 mm (Khedbrahma) to 684.0 mm (Arnej). The mean water requirement of maize during initial stage is 1.3 mm day-1, during developmental stage 1.4 to 5.0 mm day-1, during the mid season stage ETc varies between 5.0 to 6.6 mm day-1 and during lateseason stage it decreases from 6.4 to 2.5 mm day-1 . The seasonal water requirement of rabi maize varies between 330.7 mm (Khedbrahma) to 520.5 mm (Bharuch).

An investigation was carried out to study the effect of various weather parameters on the occurrence of larva and adult population of Spodoptera litura and their factors for outbreak of this pest in soybean in Banswara, Rajasthan. The moth populations of S. litura were active from August to mid- October and decreased sharply in late October. The peak appearance was observed during September-October months and corresponded with peak activity of egg masses and larval population in soybean contributed to the outbreak of this pest during the reproductive stage of the crop. Overall correlation studies confirmed that the fluctuations in the male moth catches of S. litura per pheromone trap is mainly due to weather factors like, maximum temperature, rainfall, sunshine and wind speed. Moth population in pheromone traps will be used as a warning situation indicating the occurrence of larvae in the host forpotential attack and to initiate timely management of S. litura in soybean.

Decision Support System for Agrotechnology Transfer (DSSAT v4.5) Cropping System Model (CSM) was used to study the impact of climate change and variability on productivity of different kharif (rice, maize, jowar and bajra) and rabi crops (wheat and barley) at Varanasi. Keeping in view the observed trends in climate variability, productivity of different kharif and rabi crops were simulated under plausible synthetic climatic scenarios of changes in temperature, solar radiation and carbon dioxide. Productivity of kharif crops viz. rice, maize, jowar and bajra and rabi crops viz. wheat, and barley decreased with an increase in temperature or a decrease in solar radiation above normal. However, productivity of different kharif and rabi crops increased under expected enhanced CO2 concentrations. Highest productivity decreased in barley crop (40.7%) of rabi season and minimum in rice crop (5%) of kharif season with an increase of 3.0 0C in temperature from normal. Whereas, maximum productivity decreased in barley crop (5.0%) of rabi season and minimum in jowar crop (1.8%) of kharif season with a decrease of 2.5 per cent in solar radiation from normal. Highest productivity increase in barley crop (58.2%) of rabi season and lowest in jowar crop (4.2%) of kharif season were simulated under expected enhanced CO2 concentration of 660 ppm. The maximum decrease in productivity of barley crop (45%) in rabi season and minimum inrice crop (7%) in kharif season were simulated when a decrease in temperature by 3 0C and solar radiation by 2.5 per cent from normal. Highest counter-balance on productivity of rice crop (13%) in kharif season and lowest in barja crop (-23%) of kharif season were simulated when an increase in temperature by 3 0C from normal under expected enhanced CO2 concentration of 660 ppm.

The Agricultural Production System Simulator (APSIM) Wheat model was used to test the sensitivity of wheat cropping system for the Bhopal region in Madhya Pradesh to changes in temperature (0 to 5°C from the base mean temperature) and atmospheric carbon dioxide concentration (0 to 550 ppm from the base of 350 ppm). The wheat cultivar Sujata was used for this simulation study. It was found that there was a negative relationship between grain yield and temperature while there were positive correlations of grain yield with atmospheric CO2 concentration for the region under study. However, the rate of decrease in grain yield was more for higher temperatures rise in contrast to lower temperatures, and the rate of increase in grain and biomass yield was more for higher CO2 concentration compared with the lower levels. On an average, there was 8% decrease in wheat grain and biomass yield per 1 °C increase in temperature. On the contrary, wheat grain yield increased by 33% and biomass yield by 35% with the elevation in CO2 concentration from 350 to 850 ppm. Increasing the temperature by1 oC and CO2 concentration to 500 ppm, the yield decline in wheat was lower than individual effect of increased temperature. This study showed that environmental factors have significant effects on wheat grain and biomass yield with changes in atmospheric CO2 and temperature. These findings provided a sound basis for preliminary coping and prioritizing adaptation options for the future climate change scenarios.

The projected climatic data (2071 to 2100) as downscaled by PRECIS model for different stations (Anand, Vadodara, Junagadh, Bhavanagar, Bhuj, Rajkot and Kesod) of Gujarat were analysed for climate change impact study on different crops. Results indicated that the annual rainfall during projected period would be 15 to 101 per cent higher than the base line rainfall (1961-90). Maximumtemperature would increase by 2.8 to 7.7 0C, while minimum temperature would increase by 3.8 to 5.2 0C in different parts of Gujarat. The impact of climate change on different crops (wheat, maize, pearl millet, paddy and groundnut) of Gujarat was studied using InfoCrop and DSSAT models. The results indicated that climate change will adversely affect the yields of different crops. The maximum yield reduction (-61 %) is projected in wheat and lowest in pearl millet (-<8%). Maize during kharif season would be more affected (-47 %) than the rabi season (-10 %). Similarly pearl millet in summer season will be least affected (-8%) than kharif season (-14 %).

Crop simulation models have been used to determine potential yield in a given environment. The twenty one years (1990-10) weather data and reported rice yield of Bhagalpur, Ranchi, Kalyani and Jorhat districts of eastern and north eastern region of India were used to simulate the yield under the various management conditions and compared with the reported yield of the districts. The management option included dates of sowing, irrigations and fertilizers application. The potential yield, attainable yield, yield gap etc were computed over the period. The results revealed that the rice yield of Kalyani and Ranchi districts showed increasing trend (30 to 65 kg ha-1yr-1) while decreasing trend was observed in Bhagalpur and Jorhat districts (6 to 9 kg ha-1yr-1). The potential yield simulated by model in different districts varied between 2864 to 4742 kg ha-1, while reported yield varied between 1159 to 2224 kg ha-1. The delay insowing by 15 days caused reduction in rice yield by 31 to 74 kg ha-1day-1 at different locations. The management yield gap was between 1495 to 3216 kg ha-1 while sowing yield gap was between 467.4 to 1114.0 kg ha-1 in different districts under study.

Estimation of crop coefficient (Kc) and crop evapotranspiration (ETc) using remote sensing data is essential for planning irrigation water use in arid and semiarid regions. The study was conducted to test the suitability of remotely sensed Vegetation Indices (VIs) for modeling spatial crop coefficient, choosing most appropriate vegetation index among them for modeling and applying this model toestimate water requirement of wheat. The study area consisted of wheat growing five districts situated in central Maharashtra. Images of IRS-P6, AWiFS sensor were used to generate multi temporal vegetation indices RVI, NDVI, TNDVI, SAVI and MSAVI2. The week-wise VIs were correlated with week-wise recommended wheat crop coefficients which resulted in linear relationships/models. Simple linearregression analysis showed NDVI as a superior index for predicting crop coefficients of wheat. NDVI-Kc model showed highest R² and D values of 0.895 and 0.980 respectively with lowest values of SE, RMSE and PD of 0.120, 0.113 and 4.64 respectively. The crop coefficients (Kc), obtained by this NDVI-Kc model and reference evapotranspiration (ETo), estimated by Penman- Monteith equation, were used to compute wheat crop evapotranspiration (ETc) which represents the water requirement of wheat and found varying from 378.34 mm to 439.10 mm in the study area.

A decision support system (DSS) tool has been developed for providing information on the optimum time of planting and the likely consequences of early or late planting of potato in about one hundred and seventy three locations of Nilgiris region of Tamil Nadu state in India for the most popular variety of the region i.e., Kufri Jyoti. The effect of harvest at two different durations i.e., 100 and 120 days after planting is also incorporated in this DSS. The tool consists of a database of simulated yield at 100 and 120 days after planting derived through InfoCrop-potato model. This DSS is developed with the data base generated using the daily weather data developed through weather generators and the potential yields estimated with the help of InfoCrop-Potato model. The methodology of development of the data base and the user interface of the DSS has been discussed in this paper.

Relationship of each of the weather parameters viz., maximum temperature (Tmax), minimum temperature (Tmin), rainfall (RF), morning relative humidity (RH), evening relative humidity (RH 2,) and bright sunshine hours (BSS) of six years (2007-2012) at IARI (New Delhi) was individually explored with peaks of guava fruit fly, Bactrocera zonata MAT (Male Annihilation Technique) trap catches. Peaks of fruit fly trap catches exhibited significant correlation with Tmax, RH1, RH2, RF and BSS of April 1st week and Tmin of March 3rd week. Weather-based prediction model for guava fruit fly was developed by regressing peaks of fruit fly trap catches on mean values of different weather parameters of aforesaid weeks (R2=0.80). Of the weather parameters, only Tmax, Tmin, RH2 and BSS were found to be relevant through stepwise regression.

Plum prefers temperate climate however, it has been found growing from higher hills in Srinagar to Jaipur in Rajasthan. Kala Amritsari, Satluj Purple and Titron cultivars of plum planted at experimental orchard of CCS Haryana Agricultural University, Hisar farm in the year 2001 on which the present study was done during the year 2013-14. The overall growth was observed better in Kala Amritsari followed by Satluj purple and Titron which is a late maturing variety. The thermal time required by Kala Amritsari and Satluj Purple was at par but the Titron required more thermal indices. The heat use efficiency was observed highest for Kala Amritsari and lowest for Titron whereas the photothermal index was highest in Titron followed by Kala Amritsari and Satluj Purple. The thermal units explained the 94 per cent variation in fruit yield of Kala Amritsari, 87 per cent variation in Satluj Purple and 83 percent variation in fruit yield of Titron cultivar.

The study was carried out to compare various two-parameter probability distributions for identifying the most appropriate distribution to describe the weekly rainfall data of Standard Meteorological Week (SMW) from 22 to 42 weeks in Shivalik region of India. The ‘‘best’’ distribution among different data sets has been identiûed using Anderson–Darling (AD) test for goodness-of-ût. Single probability distribution, which can represent all the data sets, was not found among the distributions studied. Weibull distribution was best fit in about nine SMW, followed by Gamma distribution showing best fit in seven weeks out of the 21 weeks studied. Comparing total rainfall at different probability level with average rainfall, it was found that minimum assured rainfall with 50, 40 and 30 per cent probability is 21.35 % lesser, 0.04 % higher and 37.25 % higher, respectively than average rainfall. Thus minimum assured weekly rainfall at 40% probability level is a better representative of long-term average weekly rainfall data of the region. Appropriate time for maize sowing should be between 25th June to 1st July as minimum assured rainfall of more than 25 mm is available with 70 per cent probability. It was found that only short to medium duration maize varieties are suitable taking into account the rainfall pattern and duration in the region.

Published: March 2022

Effect of favourable soil and canopy microenvironment, achieved through precision laser land levelling, on rabi sorghum (Maldandi 35-1) productivity was assessed for water deficit regions of Deccan Plateau of India. Laser levelled (0-0.1% grade) and adjoining unlevelled field plots (0.5-2% slope) located at six different experimental sites (silty clay soil) were selected for study. Germination percentage, weed control, temporal soil moisture depletion (SMD), canopy temperature depression (CTD) and water productivity were monitored. SMD ranged 0.46-0.60 for levelled plots indicated no impact of water stress at Panicle emergence stage i.e. 75 day after sowing (DAS). However, grain yield was reduced maximum by 62% when SMD increased from 0.68 to 0.88 for unlevelled plots. Lowering of CTD values by 0.7 to 3.2ºC, in levelled plots indicated the ability of plants to maintain cooler canopy compared to unlevelled plots. Grain yield was reduced by 0.47 t ha-1 with every increase in 0.5% of slope in unlevelled plots, whereas it was negatively correlated with SMD and CTD values in both cases. Laser land levelling showed significant improvement in uniform soil moisture distribution, seed germination, weed control, initial crop establishment and irrigation water productivity. Precision levelling significantly improved soiland canopy microenvironment which favoured to increase the sorghum yield by 27-73% and substantially saved irrigation water (30.9%) compared to unlevelled fields.

Published: March 2022

Elevated CO2 increases the C3 photosynthetic rate at the cellular level through increased carboxylation and decreased oxygenation, both of which are catalyzed by Rubisco. The study was conducted in the experimental farm of ICAR Research Complex for Eastern Region, Patna (Lat. 25°35’37" N, Long. 85°05’ E and altitude 51.8 m amsl) under open top chamber (OTC). The circular structure of OTCs were made with an aluminum frame covered with UV-treated poly carbonate sheet, which transmits 85% of natural sunlight. The higher grain yields in wheat crop under elevated CO2 were primarily due to their greater biomass production capacity and not due to a greater fraction of total biomass being partitioned to grains. The percentage of filled grains also was significantly greater in the elevated treatment. Harvest index (HI) differed significantly between the elevated and ambient treatments in both the years. However,HI of the open treatment was significantly lower than the other two. Seed yields under elevated CO 2 were greater than the ambient and open field treatment.

Published: March 2022

A modificação da paisagem pela tendência crescente de condomí­nios residenciais horizontais, na parte norte da região costeira do estado do Rio Grande do Sul, é uma preocupação atual, devido essa região abrigar ecossistemas raros, como áreas úmidas e grandes lagoas salobras, caracterizando possí­vel vulnerabilidade ambiental. Essa forma de ocupação traz também consequências em relação à igualdade social, uma vez que integra áreas construí­das para baixa densidade populacional. O Barômetro da Sustentabilidade serve para mensurar o grau de sustentabilidade, permitindo considerar aspectos ambientais, econômicos e sociais e é considerado um importante instrumento para a análise da sustentabilidade. O objetivo desse estudo foi analisar a dinâmica espaço-temporal do grau de sustentabilidade dos municí­pios que integram a região costeira, para o ano de 2000 e 2016, utilizando o Barômetro da Sustentabilidade. Foi aplicado o Barômetro da Sustentabilidade para avaliar o grau de sustentabilidade dos municí­pios da região costeira do Rio Grande do Sul, realizada a distribuição e análise espacial do grau de sustentabilidade municipal, através do Índice de Moran. O estudo possibilitou compreender a evolução negativa do grau de sustentabilidade, entre o ano de 2000 e de 2016, a correlação espacial positiva e significativa da sustentabilidade nos dois perí­odos e as principais fragilidades e potencialidades relacionadas ao grau de sustentabilidade de cada municí­pio e da região.

Este estudo tem como objetivo verificar as potencialidades, entraves e demais aspectos relevantes para a implementação da Indicação Geográfica do licuri do Semiárido Baiano. A metodologia utilizada foi da triangulação de dados, a partir do Cí­rculo Virtuoso da Qualidade Ligado à Origem da Organização para a Alimentação e Agricultura. Identificou-se a notoriedade do Semiárido Baiano quanto ao saber-fazer da cultura do licuri, bem como apontou-se as fragilidades dessa cadeia produtiva como a inexistência de parâmetros especí­ficos de qualidade na etapa do beneficiamento. A modalidade de Indicação Geográfica mais factí­vel à Região é a Indicação de Procedência, dado o requisito da notoriedade confirmado. Concluiu-se que há evidências históricas e de mercado que comprovam que o Semiárido Baiano é reconhecido como centro produtor e extrator do licuri.
