Authors: Windt Johann , MacDonald Kerry , Taylor David , Zumbo Bruno D. , Sporer Ben C. , Martin David T
Published: September 2020

The current technological age has created exponential growth in the availability of technology and data in every industry, including sport. It is tempting to get caught up in the excitement of purchasing and implementing technology, but technology has a potential dark side that warrants consideration. Before investing in technology, it is imperative to consider the potential roadblocks, including its limitations and the contextual challenges that compromise implementation in a specific environment. A thoughtful approach is therefore necessary when deciding whether to implement any given technology into practice. In this article, we review the vision and pitfalls behind technology's potential in sport science and medicine applications and then present a critical decision-making framework of 4 simple questions to help practitioners decide whether to purchase and implement a given technology.

Authors: Gorbunov Vassily Gennadievich , Korff Christian , Stroppel Catharina
Published: September 2020

Статья посвящена новому, активно развивающемуся направлению современной математики - изучению связи квантовых интегрируемых моделей и исчисления Шуберта для колчанных многообразий. В статье предлагается геометрическая конструкция решений уравнения Янга-Бакстера и алгебр, связанных с ними, которые называются алгебрами Янга-Бакстера. Эти алгебры играют центральную роль в квантовых интегрируемых системах и точно решаемых (интегрируемых) решеточных моделях статистической физики. Мы покажем на примере классической геометрии многообразий Грассмана, как появляется указанная выше связь. Конкретно, мы отождествляем алгебру конволюций, возникающую в эквивариантном исчислении Шуберта, с алгеброй Янга-Бакстера вырождения асимметричной шестивершинной модели, так называемой пятивершинной модели. Мы покажем также, как, используя наши методы, можно построить действие факторов универсальной обертывающей алгебры для алгебры токов $\mathfrak{sl}_2[t]$ (так называемые алгебры типа Шура) на тензорных произведениях ее представлений вычисления $\mathbb{C}^2[t]$. Наконец, мы связываем нашу конструкцию с когомологической алгеброй Холла для колчана $A_1$.

Authors: Brassard Kevin , Forgues Geneviève , Boivin-Mercier Allexe , Gagnon Cynthia
Published: September 2020

Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS) is a degenerative spinocerebellar disease with pyramidal, cerebellar, and neuropathic impairments. Recent studies highlight possible deficits in cognitive functions like language. Psychometric tests selection implies careful consideration due to upper limbs incoordination and dysarthria. The objective of this study is to document the applicability of 37 neuropsychological and 2 psychological tests in 8 individuals with ARSACS aged between 20 and 60 years. All tests were rated on 4 applicability criteria using a 3-level rating scale: A for excellent; B for acceptable; C for reconsider. Most tests posed few or no applicability limits with ARSACS patients. However, certain tests (e.g., Leiter-3 and Raven’s Standard Progressive Matrices) are not recommended due to significant issues related to applicability. These results may help clinicians and researchers working with this population to select evaluations and tests applicable in this population.

parasitoid, Trichogramma chilonis, larval parasitiod, Cotesia flavipes and pupal parasitoid, Tetrastichus howardi against sugarcane internode and stalk borer in RBD with a plot size of 72sq.m. The incidence of internode borer ranged from 2.34 to 4.91% in treated plot as compared to control (7.87%) in August, however during October incidence ranged from 2.14 to 6.86%.At harvest, minimum incidence of internode borer (5.62%) was observed in T. chilonis followed by C. flavipes (7.52%) released plots. The released parasitoids are more active in the field for its parasitisation and multiplication which result a reduction in the incidence of INB in released plots where as beyond October the prevailing low temperature, appeared to be non-conductive for its mating and field parasitisation. The incidence of stalk borer during August and October was low (1.03- 5.54%). At harvest minimum incidence (5.55%) was observed in C. flavipes followed by T. howardi release plots (10.92%) as against 17.24% in control. Removal of dry leaves and late shoots was observed to reduce the damage by migratory borer larvae in August and October. The results indicates that parasitoids (egg, larva and pupal) play a significant role in the management of INB and SB to check the spread and lowering the incidence of this pests. It is suggested that a working of these parasitoids can be exploited in programmes for management of sugarcane stalk and internode borer.

Published: September 2020

Methane is second most potent greenhouse gas emitted under anaerobic condition in rice soils. Effects of different nitrogen fertilizer application on methane emissions in flooded paddy field were studied. The experiment was laid out in a randomized complete block design with three treatments and three replications. The treatments were control (0 kg N ha-1), urea (120 kg N ha-1) and ammonium sulfate (120 kg N ha-1). In all treatments P (60 kg P2O5 ha-1) along with K (40 kg K2O ha-1) were also applied as basal dose. The cumulative seasonal methane flux was highest in urea 36.3 (kg ha-1) followed by control 35.2 (kg ha-1) and ammonium sulfate 28.5 (kg ha-1). Ammonium sulfate application reduced total seasonal emission by 19.5% as compared to control while it reduced CH4 emissions by 21.6% as compared to urea application. On the basis of this study we can conclude that application of ammonium sulfate is an effective tool for mitigating methane emissions from rice soils.

Authors: Kumar M. , Sharma P. K. , Sharma P. K. , Kumar N.
Published: September 2020

Conventional procedures of identification are laborious and time consuming because they depend on growth of microorganism in that particular environment and hence, sometimes, give misleading results while molecular methods relies upon generating a large number of copies of a specific part of its genome for identification of unknown isolates and enables the problem of poor identification. The identification of a microbial isolate to genus level imparts a partial characterization of the isolate revealing a lot of information about that organism. Lactic acid bacteria are very significant to human health due to their probiotic attributes, production of antimicrobial substances and subsequently to inhibit pathogenic bacteria. Bile tolerance has been one of the major probiotic criterion while selecting the isolate for probiotic properties. This work aims at looking directly at the genome of bile tolerant Lactobacillus isolates using genotypic and phenotypic characteristics. The isolates were identified by sequencing specific region of 16 S r DNA segment, after amplification by PCR, and then comparing the results to sequences from related database. The results from both conventional and molecular methods were then compared. Twenty five isolates (25) of Lactobacillus fermentum were isolated from fecal samples and identified using API- 50 CH. The isolates were further identified using molecular methods using polymerase chain reaction (PCR) for amplification of 16S rRNA gene to confirm their identities. The genotypic characterization however showed that 84% of the organisms identified using conventional method as L. fermentum correlated, while 16% did not correlate; 2 were identified as Lactobacillus planterum, 01 as L. delbrueckiiand 01 as L.paraplanterum.

Cassia obtusifolia Linn. is commonly known as “Takla” or “Chakunda” in India, a common weed, also used as vegetable Family-Caesalpiniaceae. Macroscopic and microscopic examinations of the different organ, observations and differential microchemical test have been carried out for the authentication of the samples. Physiochemical values such as the Moisture contents, percentage of total ash, acid insoluble ash, acid soluble ash, water soluble ash, extractive values like petroleum ether-soluble extractives, ethanol-soluble extractives, methanol-soluble extractives and water-soluble extractives were calculated as well as colour reactions of powder and extract with different chemicals were performed to observe fluorescence analysis. The extracts were subjected to qualitative screening test for various constituents. This revealed the presence protein, glycosides, alkaloids, tannins and phenolic compound, steroid reducing sugars, saponin glycosides and fats. These observations will help in the Pharmacognostical identification and standardization of the plant as a drug in the crude form and also to distinguish the material from its adulteration.
Infochemicals: An effective and environment friendly management of insect pests for sustainable agriculture
Authors: Kumar Joni
Published: September 2020

Chemical signals and cues have been collectively called semiochemicals or infochemicals referring to “a chemical substance, which in a natural context, is implicated in the transfer of information from one individual to other that results certain behavioral and physiological changes in response in one or both. Infochemicals that mediate interactions between members of the same species are collectively referred to as pheromones, and can be classified as sex pheromone, aggregation pheromone, alarm pheromone, trail marking pheromone on the basis of their functions etc. Allelochemicals are also infochemicals which cause an insect to respond interspecifically. They include a more number of chemicals than pheromones, and can be grouped into: allomones, kairomones, apneumones and synomones. The idea of infochemicals using for management of insect pests in agricultural, horticultural, forestry and storage has been a driving ambition through few decades of pheromone research. Several chemicals have been identified from insects that can be used in monitoring of native and invasive pest and also to protect the plants against herbivores. They can also be used as mass trapping, annihilation, and behavior manipulation of insect in host finding. Since these compounds are species specific, highly biodegradable and require in minute quantity, they could be exploited as green alternative to insecticides for ecofriendly management of insect pest for sustaining agriculture growth.
Policy options to leverage agriculture to improve nutrition security
Authors: Tripathi Priyanshu , Tiwari Adya
Published: September 2020

Accelerating undernutrition reduction in India requires realigning agriculture and rural development policy to empower women in agriculture. Resources targeted to women and women’s groups significantly improve agricultural productivity, women’s control of resources or assets, and health and nutrition outcomes. The country should promote women’s cooperatives, producer women’s groups, and other forms of group efforts, where they do not already exist. This would enable women to overcome the constraints of small, marginally profitable land holdings, thereby improving the dissemination of agricultural technology and other inputs, as well as marketing of produce. The National Rural Livelihoods Mission (NRLM) under the Ministry of Rural Development offers a significant potential for convergence with the agriculture sector to empower women to care for themselves and their children. NRLM’s federations of Self-Help Groups (SHGs) could radically alter the balance of power not only in the markets they participate in as both producers and consumers, but also in their communities and households.Women’s groups, including SHGs under NRLM, can become instrumental in meaningful convergence of health, nutrition, education, and other broad-based schemes addressing the deeprooted causes of undernutrition. Examples of such group-centric pro-nutrition approaches include producing and consuming nutrient-rich foods through homestead horticulture and poultry interventions; establishing and maintaining micronutrient food fortification units; producing and marketing low-cost, nutrientdense supplementary foods; developing primary food processing; enabling women and their children to access essential health and nutrition services; and catalyzing critical behavior change for optimal health and nutrition outcomes in the long run through community mobilization, including the involvement of Panchayati Raj Institutions, around nutrition-specific issues and actions. Empowering women in agriculture which is essential to India’s nutrition security requires securing women’s rights to land, providing efficient and effective legal support, and enhancing women farmers’ access to inputs. For example, entitling women in land records as cultivators on family farms, where women operate the land registered under the name of the male household members, would make a significant difference in accessing various government program benefits.

Authors: Kumar Ashwani , Kumar Surjeet
Published: September 2020

At present we are facing the challenges of implication of WTO on Indian agriculture. Thus the extension would focus the quality cost of production, market led extension and cyber application in extension. These challenges require the change in present extension services. Private extension's filling up the gap which is created by the government extension agencies. This transition from resource based to technology based system agriculture however places greater responsibility upon the agriculture extension sector. Keeping in view the situation this study is carried out in district Meerut Four blocks were also chosen from the twelve blocks of district Meerut. Accordingly a total of eight villages were selected for the study. Thus a sample size comprised to two hundred farmers respondents. The inference that could be drawn from the analysis is that the respondents have realized the advantages of privatization in case of cultivation practices of medicinal plants and cultivation practices of fruits and vegetable crops. Besides farmers prefer those agencies that responsibility to supervise agriculture operations and ensure better income i.e. marketing to farmers. It is evident the study area that seed production is confirmed to commercial and horticulture crops and mainly managed by private agencies. It is also concluded from the analysis of the study that mostly fanner are willing to pay extension services rendered. It is true that farmers will be ready for cost sharing only when the benefits and w and weight their cost (Samanta,1977).

Basmati rice is an important staple food grain crop in the world. Basmati rice is an important export commodity among the food grains. The biotic and abiotic factors are adversely affected the Basmati rice but Basmati rice blast caused by Pyricularia oryzae Cavara (synonym Pyricularia grisea Sacc). The anamorph of Magnaporthe grisea (Herbert), is one of the most destructive and wide spread diseases as compared to other diseases of Basmati rice. It causes leaf blast, neck blast and panicle blast of paddy. This disease generally causes yield loss of 10-20 percent but in severe cases yield loss may reach up to 80 percent. Management of blast disease using healthy seed, resistance varieties, many biological controls like as T. harzianum, T. viride and P. fluorescens @10g/kg by seed treatment and foliar spray. The chemical control by fungicides such as carbendazim, tricyclazole, isoprothilane, tebuconazole, hexaconazole reduced leaf but not neck blast; on the contrary, tricyclazole was effective against neck blast and panicle blast.

First group (T) was fed with 60 gm mineral mixture daily till 90 days of lactation. Other groups (C) of 10 animals were not fed additional mineral mixture, which is farmers practice in that particular area. The farmers were not fed scientific method of feeding. They could not added proper quantity of mineral mixture in balance ration. To keeping in mind a trial was conducted in Ghaziabad District since 2016-17 to 2017-18. Milk yield of these animals was recorded by their owners and these values were averaged for fortnightly interval. Milk production parameters like average daily milk yield, peak yield and total milk yield were compared between treatment and control groups. It was observed that average daily milk yield, peak yield and total milk yield were found significantly (P less than 0.05) higher by 11.04, 12.37 and 11.61% in mineral mixture fed group than control group. On the basis of this, it is recommended that continuous feeding of mineral mixture bettered performance of milk yield in buffaloes.

Rootstocks have become a major component is present day viticulture. Till date, there are several rootstocks evolved of which some have become commercial in many advanced countries. Different types of grafting and budding methods have been tried in grapes with varying success rates. Hence, to standardize the same for Pusa Urvashi, different rootstocks (Pusa Navrang, Dogridge A, SO4 and H-144) involving different grafting methods (wedge, side and bench grafting) were tried. The grafting factor like months (February, March and August), grafting height (15, 30 and 45 cm.) and growing condition was glasshouse. The highest success of graft take was registered in wedge (87.0%) followed by side (62.5%) in all the three months while in bench grafting (48%) in February month. The graft take was maximum at the height of 15 cm, while the minimum was noted at 45 cm. Of the three grafting months, February was found best with respect to percentage graft success and survival.

An experiment was conducted in the Horticulture Farm of Agriculture and Forestry University to demonstrate the effects of different fertilizers on the yield and yield parameters of okra (var. Arka Anamika). The experiment was laid out in Randomized Complete Block Design (RCBD) consisting of seven treatments and three replications. The various treatments used in the experiment were goat manure, sesame cake, mustard cake, synthetic fertilizer (NPK), poultry manure, vermicompost and untreated control. The required dose of nitrogen was fulfilled by the fertilizer itself whereas insufficient amount of phosphorous and potassium was fulfilled by addition of single super phosphate and muriate of potash respectively. The fertilizers were applied on the basis of recommendation given by the Nepal Agriculture Research Council (NARC). The effect of poultry manure on number of open flowers and number of fruits at 40 DAS was found superior. The effect of poultry manure on plant height, number of leaves, plant diameter was found superior at 50 DAS. Goat manure produced the superior result on number of open flowers at 50 DAS. Poultry manure on the number of leaves and plant height produced the significant result at 60 DAS. Synthetic fertilizer responded well to number of fruits at 60 DAS. Sesame cake produced the superior results at 70 DAS on number of buds. Poultry manure responded well to all the parameters and produced the yield of 20 qt/ha with the BC ratio of 1.77. This experiment suggests the farmers to use the poultry manure to get the highest economic return. Vermicompost and mustard cake producing the superior and significant yield in this research are not recommended as they have low BC ratio unless effective measures are encouraged to reduce the cost of this fertilizers.

University of Agriculture and Technology, Kanpur, Uttar Pradesh, India to evaluate the effect of nutrient management practices on growth and yield of pearl millet (Pennisetum glaucum (L) R. Br. Emend. Stuntz.). Highest yield was observed in 5t FYM/ha application over control. Each unit increase in N level led to significant increase in growth, yield attributing characters and yield of pearlmillet. The maximum grain yield (24.2q/ha) was recorded with highest N level. Combined inoculation of Azospirillum + PSB increased the growth, yield attributes and yields significantly. The monetary returns were found in similar trends. Application of organic manure and bio-fertilizers resulted in desirable post-harvest soil status with more organic carbon (OC), Nitrogen (N), Phosphorus (P) and Potash (K).
Quantitative environmental impact assessment on groundwater quality using geoinformatics techniques
Authors: Natarajan Kavitha , Kanaka S.
Published: September 2020

Availability of quality freshwater is one of the most critical environmental issues of the twenty first century (UNEP, 2002). Urbanization leads to the environmental pollution, i.e., urban growth leads to the increasing of slums, solid waste disposal, provision of transport facilities, conjection and groundwater contamination. Groundwater is an important water resource for domestic and agriculture in both rural and urban parts of India. Pollution of groundwater comes from many sources. Groundwater contamination in a major issue, especially in industrial areas especially like Dindigul. The presence of large number of tanniers and allied industrial unit such as dyeing and bleaching units in and around the town are the main factors, which affect the environmental quality of the town. Dindigul town is not having the physical expansion since 1981 with an area of 14.01sq.km. Only wards are increased by enjoying the rapid growth of population. Dindigul is the main industrial hub for the Tanneries. Effluents from the tanneries are discharged in to streams which drain into ponds, thereby polluting the ground water sources and cultivable land. These values are more than the permissible limit in and around the tannery cluster compared to other parts of the area. The pH,CO3, Na, Ca, Mg, NO3, and SO4 values of all groundwater samples are within the permissible limits but all the EC, TDS, HCO3and K values are exceeding the permissible limit. According to TH and Cl 6 samples are exceeding the prescribed limits. There are about 80 tanneries spread within 4-6 kms radius in the south western part of the town i.e., near Paraipatti, so ground water pollution is very high compared to other places. Madurai road tanneries are located so in Begampur near Annamalayar school pollution is high. R. M. Colony is having the highest household wastages because of its vertical expansion so in that areas also pollution is high.

Published: September 2020

Indian processed vegetables in International markets accelerate the growth of Indian economy. Studying the changes in share of processed vegetables to different countries, improve the welfare of farmers, processers and exporters. In this regard, an attempt was made to quantify the changing structure of Indian processed vegetables exports. The main objective of the present study was to analysis the growth and the direction of trade in processed vegetables export. In this regard, secondary data, mainly quantity of processed vegetables exports from India was collected from APEDA, for a period of 1995-96 to 2017-18. Growth rates was estimated by using the exponential growth model and the Markov chain analysis model was computed through linear programming method to assess the transition probabilities for the major Indian processed vegetables export markets using Lingo Programming computer package. Accordingly, processed vegetables export market have positive double digit growth rate, UK retained 22.5 per cent, countries pooled under ‘others category’ retained 32.4 percent of share of Indian processed vegetables export. That the countries pooled under ‘others category’ and UK would be the more stable importers of the processed vegetables from India in future and country like Germany and Netherland was not found as the stable importer.

Authors: Paudel S. , Pantha P.
Published: September 2020

Tomato (Lycopersicon esculentum) is highly perishable and has potential for processing industries in bumper producing seasons in Nepal. The study on judicious use of nitrogen and potassium levels was aimed to explore the quality attributes along with the shelf life of tomato fruits. Three levels of nitrogen comprising 0 kg/ha (N0), 100 kg/ha (N100), 200 kg/ha (N200) and four levels of potassium 0 K2O kg/ha (K0), 80 K2O kg/ha (K80), 160 K2O kg/ha (K160), 240 K2O kg /ha (K240) were used as treatments in randomized complete block design with three replications at Chitwan (Inner Terai) Nepal. Tomatoes at breaker stage were harvested from the field and 10 fruits from each treatment per replication were kept for physiological weight loss, color rating and shelf life in ambient condition (17.5±3 0C and 80.5±6.5 % RH). Fruit quality with respect to physicochemical properties like firmness, TSS, TA, pH and Vitamin C was assessed at the end of shelf life. Higher potassium levels hasten color development and increased TSS, firmness and vitamin C content. Physiological weight loss was greatly reduced and extended shelf life was achieved with 100 kg N/ha and 240 kg K2O/ha.

Published: September 2020

Amarsimhas Amarkosa (Namalinganusasanam) is an ancient Sanskrit thesaurus. It has bearing on teaching of Sanskrit but also includes information on nearly all facets of human life inclusive of Indian biodiversity. It is composed of Sanskrit verses which are replete with references to Sanskrit common plant names. The present author assessed these names and equated with Latin plant names and their respective families. This attempt deals only with the exotic plant species to decipher pant invasion in the erstwhile by consulting relevant taxonomic literature. A total of 64 species belong to 58 genera and 37 Angiospermic families. The data accrued is discussed in the light of plant invasion and implications in the then and present India.
