ThesisItem Open Access Studies on the efficacy of Rhizobium and PGPR consortia inoculants in Urdbean (Vigna mungo L.)(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-01) Joshi, Neha; Ramesh ChandraThe investigation was carried out to study the efficacy of Rhizobium and PGPR consortia inoculants in Urdbean (Vigna mungo L.). Compatibility of the used Rhizobium sp. and PGPR organisms was studied in laboratory and efficacy of their mono and consortia inoculants in urdbean was studied in field trial during kharif 2019 at N. E. B. Crop Research Centre, G. B. Pant Univ. of Agric. & Techn., Pantnagar. Ten treatments consisting inoculation with Rhizobium and PGPR strains, alone and as consortia, RDF and an uninoculated control were laid out in RBD in 3 replications. The test crop variety was Pant Urd-31. The results from in vitro studies indicated that the used Rhizobium sp. and PGPR strains were not having antagonistic interactions. Viable population of both the Rhizobium sp. and PGPRs was slightly more when grown together in consortia than individually in MSB. Individual or consortia inoculation treatments of Rhizobium sp. and PGPR increased the root nodule number numerically ranging from 17.3 to 36.9 % at 30 DAS, 3.6 to 36.6% at 45 DAS and 1.6 to 14.0% at 60 DAS, root nodule dry weight from 28.7 to 69.6% at 30 DAS, 5.8 to 32.0% at 45 DAS and 35.0 to 71.4% at 60 DAS and plant dry weight from 10.5 to 27.9% at 30 DAS, 3.8 to 22.5% at 45 DAS and 12.1 to 21.1% at 60 DAS over the uninoculated control. Grain yield due to different treatments showed significant increases of 17.3 to 35.1% while straw yield increased numerically from 12.4 to 24.0% over the uninoculated control. Inoculation of Rhizobium sp. and PGPR as individual and in consortia increased grain N content, by 4.8 to 10.1%, straw N content, by 24.5 to 49.0 %, grain N uptake, by 26.3 to 48.7% and straw N uptake, by 49.2 to 80.3% over the uninoculated control. Different inoculated treatments also numerically increased the grain and straw P content from 6.9 to 14.2% and 17.4 to 37.3% and P uptake from 25.4 to 53.8% and 32.8 to 71.2% over the uninoculated control, respectively. All the treatments, except PUK-171 and PUK-46B6, improved the available N in soil, by 7.3 to 24.5% and available P, by 10.9 to 47.4%, over the uninoculated control. Individual or consortia inoculation treatments of Rhizobium sp. and PGPR significantly improved the activities of dehydrogenase, acid and alkaline phosphomonoesterases in soil ranging from 7.6 to 25.3 %, 21.2 to 46.6% and significantly from 46.96 to 116.6%, respectively. Consortia inoculant of PUR-34 + PUK-46B6 was found most efficient by registering maximum net return of Rs. 54759 ha-1 and B:C ratio of 2.35 than others. It was followed by consortia inoculants of A-3 + PUK-46B6 and PUR-34 + PUK-171 in performance.ThesisItem Open Access Value chain analysis of vegetable pea in hilly region of Kumaon division of Uttarakhand(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-11) Joshi, Neha; Singh, H.N.Agriculture is the mainstay of Indian economy thereby transformation in it is possible through the development of agriculture sector as a whole. Horticulture production as a sub-sector of agriculture plays a vital role in its development,by contributing 30.4 per cent to the GDP of agriculture. Diverse climatic conditions of Uttarakhand impart the state with distinctive advantages in terms of agriculture, particularly in horticulture. It contributes more than 30 per cent in state’s agricultural sector’s gross domestic product. Uttarakhand ranks 9th in terms of pea production in India. Superior quality of pea produced from hills attracts the consumer to pay premium prices for the produce. Multistage sampling was adopted in the study for the selection of 80 respondents. 60 pea producers were selected from 2 districts, Nainital and Almora of hilly region of Kumaon division and 10 wholesalers, 4 rural collectors, 3 local market traders and 3 retailers were selected purposively from Haldwani mandi, the major mandi dealing with the pea of hilly region of Kumaon divison. The study was directed towards achievement of three specific objectives viz, mapping of value chain of pe, to identify the determinants of market outlet choice decisions of the pea producers and two rank the onstraints faced by producer as an actor art various stages of value chain. Pea was discovered as low input requiring but high returns reaping enterprise in the study area. Input suppliers in form of wholesalers, private shopkeepers and some government department, producers, wholesalers or wholesaler cum commission agents, rural collectors, local market traders and retailers (itinerant and district retailers) were identified as actors of the value chain of pea in the study area. Producers were recognized as the major actor in terms of activities performed right from production to marketing. While wholesalers were identified as the major actor in terms of governance of chain. Wholesaler possess control over the chain as it was identified with properly coordinated network for collection of market information in terms of both demand and supply of pea produce from farmers and traders respectively. Channel 1: Producer - Wholesaler - District Retailers – Consumers, Channel 2: Producer - Wholesaler - Itinerant Retailers – Consumer, Channel 3: Producer - Rural Collectors – Wholesalers – District Retailers – Consumers, Channel 4: Producer – Rural Collectors – Wholesalers – Itinerant Retailers – Consumers and Channel 5: Producer - Local market traders – Consumers, were the identified marketing channels. Channel 1 was discovered as prime one in terms of disposal of 70 per cent of produce at second stage of marketing followed by channel 2. Channel 5 was discovered as shortest one, providing maximumproducers’ share in consumer rupee. Producers were discovered to incur highest marketing cost followed by rural collector,district retailer, wholesaler cum commission agent, itinerant retailers, and least by wholesaler and district retailers.Transportation cost appeared as prime reason of high marketing cost accrued by most of the actors. Total gross marketingmargin accounted highest in channel 3 and 4 due to large difference between the price recurved by producers and price paidby consumers to retailers. For identification of determinants of outlet decision of producers, multinomial logit model wasemployed. Its result indicated that quantity supplied and distance from the market impart positive significant impact onchoosing rural collector as the outlet, i.e. probability of choosing rural collector increases with 1.4 and 3.3 per centrespectively with the increase in per unit quantity supplied and per unit increase in distance from the market, while access tomarket information imparts negative significant impact i.e. probability of choosing rural collector over wholesaler as outletdecreases by 25.85 per cent as producer get access to market information. While in case of choosing local market trader asoutlet quantity supplied pose a positive impact i.e. probability of choosing local market trader as outlet increases by 1.07 percent with the increase in per unit of quantity supplied while access to irrigation and market information pose a negative impact and reduce the probability of choosing local market trader by 22.6 and 36.52 per cent respectively as producer getaccess to irrigation and market information.Regarding recommendations, a well organized input supply system and improvement in irrigation facilities wereidentified crucial, due to the constraints faced by actors at input supply and production stage of value chain andestablishment of small outlets near the production hotspots to encourage direct marketing and development of strongbackward and forward linkage for proper coordination within the actors of value chain to reap maximum benefit fromperfect value chain management can be drawn in the study area.ThesisItem Open Access A comparative study of educational aspirations & achievement motivation of visually impaired & sighted adolescents enrolled under inclusive & exclusive education(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-08) Joshi, Neha; Singh, RituAn individual receives impressions of the world through his sense organs. Senses are said to be the gateway to knowledge. More impressions reach the brain through the sense of sight than through all other senses combined. It has been thus, said that “eyes are the windows of the soul”. Thus, lack of sight makes the individual blind and aloof from the physical world. The present study was undertaken to assess the difference, if any, exists in the levels of educational aspirations and achievement motivation of visually impaired and sighted enrolled under inclusive and exclusive education in Uttarakhand. It has been realized that, there is a need to identify whether educational aspirations and motivation in inclusive and exclusive settings of visually impaired adolescent and sighted adolescent does make any differences. The sample for the present study comprised of four groups viz. a) visually impaired adolescents from exclusive educational settings b) visually impaired adolescents from inclusive educational settings c) Sighted adolescents from inclusive educational settings d) Sighted adolescents from exclusive educational settings .50 respondents were randomly selected under each group of sample from the identified locale so as to make a total sample of 200 respondents for the study. Educational aspiration and achievement motivation of the population under study was assessed by employing two tools viz. Level of Educational Aspiration Test (LEAT) developed by Dr. Yashmin Ghani Khan.(1999) and Achievement Motivation Scale (n-Ach) developed by Prof. Pratibha Deo and Dr. Asha Mohan(1985). The present study revealed that Education aspiration was found to be significantly higher in visually impaired adolescents of exclusive education as compared to visually impaired adolescents of inclusive education in all the domains of educational aspiration except reality of aspired goals. In sighted adolescents education aspiration was found to be significantly higher in inclusive education in family support and pupil’s view domain. However for the pupil’s effort and reality of aspired goals domains in sighted adolescents from exclusive education were found to be higher. Achievement motivation was found to be significantly higher in visually impaired adolescents of exclusive education as compared to visually impaired adolescents of inclusive education Socio –demographic and socioeconomic variables also influenced the levels of educational aspiration and achievement motivation. Significant difference was observed in terms of level of educational aspiration across gender in inclusive education of visually impaired adolescents and sighted adolescents of exclusive education, across birth order in inclusive and exclusive education of sighted adolescents, across number of siblings in inclusive and exclusive educational settings of visually impaired adolescents, across visual impairment in exclusive education, across visual impairment onset in inclusive education, across father’s and mother’s education in inclusive and exclusive education of visually impaired adolescents and sighted adolescents. No Significant difference was observed across family income and parent’s occupation. Significant difference was observed in terms of level of achievement motivation of visually impaired adolescents from inclusive education across number of siblings . Across father’s and mother’s education in inclusive and exclusive education of visually impaired adolescents and sighted adolescents, across father’s occupation of visually impaired adolescents under inclusive education, across family income visually impaired adolescents from exclusive education significant difference were found and no significant differences was observed in other variables under level of achievement motivation.ThesisItem Open Access Characterization of germplasm for yield, its components and quality traits in wheat (Triticum aestivum L. em.
