An Assessment of in- Service Training Needs for Extension Functionaries in Kota Division of Rajasthan

Paper ID- AMA-12-03-2022-11213

The changing scenario in agriculture, economy and communication has also increased the need for improving the skills of extension personnel. The first step in improving the skills of extension personnel would be to assess their training needs. The study was conducted in the year 2020-21. The present study was conducted in the Department of Agricultural extension and communication and the Kota division of Rajasthan was purposively selected for the study. The respondents were the Agricultural extension functionaries and the sample size was 130. The important training needs aspects were subject matter and extension ability. The important training need areas identified in order of importance are Soil science, Agronomy Marketing, Govt. polices and post harvesting technology, Plant protection and Extension ability. As the training needs of extension personnel changed over time, hence, training needs assessment should also be done on a regular basis and the important areas in which the extension personnel needs training should be considered while planning training for the extension personnel. Thus, appropriate measures should be taken by the department and other training institutions in addressing their grievances.

Effect of Genotypes under Varying Fertility Levels and Bio-fertilizer Inoculation on Nutrient Content, Nutrient Soil Status and Quality of Mustard {Brassica juncea (L.) Czern & Coss.}

Paper ID- AMA-12-03-2022-11211

Mustard is second most important edible oil seed crop after soybean and known by the name of Indian mustard. It’s very useful for human health and making food. There were several genotypes, fertilizer and bio-fertilizer are used in this experiment. The objective of this experiment is that response of genotypes and bio-fertilizer on yield of mustard. The experiment was conducted in Rabi October 2020 in humid and sub humid condition. The experiment used a factorial randomized block design with three replications and two factors. The first factor was four genotypes of mustard (Bio-902, Giriraj, RH-0749 and NRCHB-101) and second factor was four fertility levels (75% RDF, 100% RDF, 75% RDF + Bio-fertilizer and 100% RDF + Bio-fertilizer). The maximum seed yield, nutrient uptake, available nutrient in soil and oil content were obtained under the genotype Giriraj and fertilizer 100 % RDF + Bio-fertilizer. Hence, genotype Giriraj with the application of 100% RDF + Bio-fertilizer were proved economically viable in mustard crop under prevailing agro-climatic conditions of Rajasthan.

Cultural, Morphological and molecular variability among the surveyed isolates of Fusarium oxysporum Schlecht causing wilt of isabgol

Paper ID- AMA-12-03-2022-11210

Fusarium wilt becomes a serious problem in isabgol growing agro climatic zones of Rajasthan. This study was undertaken to identify and characterisation through morphological, cultural and to determine the genetic diversity of isolates of Fusarium oxysporum. Among the isolates, maximum growth and sporulation was recorded in UDP Fo-1 showed 90 mm colony diameter with whitish orange irregular fluffy growth with yellowish pigmentation and 4.20x106 conidia/mm2 sporulation. Whereas Isolate SRH Fo-1 showed minimum growth 65.0 mm colony diameter with white plenty mycelium irregular growth with light yellow pigmentation with 2.2x106 conidia/mm2. Molecular characterisation based on the reproducibility of the PCR amplification. RAPD is an effective tool to differentiate geographically and genetically isolated populations. The PCR result from 10 RAPD primers was repeated three times to assess reproducibly. By using 10 RAPD primers, a total of 112 reproducible bands were amplified, out of which 88 (78.5%) were polymorphic and 24 (21.42%) were monomorphic. Similarity coefficient among the isolates ranged from 1.9 per cent (CHI Fo-1 and UDP Fo-1) to 74.6 per cent (PRA Fo2 and CHI Fo1). Genetic similarity coefficient was found relatively low among all the isolates, which ranged from 0.012 to 0.74. The maximum similarity value (0.746) was obtained between isolates PRA Fo2 and CHI Fo1, both of which belong to Pratapgarh and Chittorgarh.

Breeding Pumpkin (Cucurbita moschata Duch. Ex Poir) for High β – Carotene Content through High Performance Liquid Chromatography Analysis

Paper ID- AMA-12-03-2022-11208

There is a diverse variety of pumpkin types found in nature, and their potential as a source of pro-vitamin A can be evaluated with the goal of using them in traditional plant breeding or biofortification projects with the goal of increasing the beta-carotene content. The objective of the study was to determine the β-carotene contents in locally available varieties and their hybrids (L x T fashion) of fully ripened pumpkins to verify their use in further breeding program as parents. High Performance Liquid Chromatography were used to identify and quantify the β-carotene contents in. In this study carotene content in pumpkin fruit flesh varied from 4.70 µg per g (L2) to 24.57 µg per g (L4) in lines whereas in testers it ranged from 7.73 µg per g (T3) to 11.59 µg per g (T2). Among the 18 crosses of study, the lowest and highest values of β carotene content recorded by the crosses L4 x T1 (2.54 µg per g) and L3 x T2 (89.60 µg per g) respectively. In total, six hybrids exceeded the parents in their β carotene content above the mean value (20.57 µg per g). The highest carotene content recorded by L3 x T2 (89.60 µg per g) followed by L1 x T1 (40.32 µg per g) and L2 x T2 (28.06 µg per g).

Induced mutagenesis for male sterility in finger millet (Eleusine coracana L. Gaertn.)

Paper ID- AMA-10-03-2022-11202

Finger millet is highly self-pollinated crop in which emasculation is extremely difficult due to very small size of flowers. The presence of the male sterility will make crossing easier in finger millet which helps in generation of variability and exploitation of heterosis. Therefore, an investigation was aimed to identify male sterile line(s) in M3-M4 generation of, two gamma rays irradiated varieties of finger millet, GPU 28 and KMR 204. Plants with reduced pollen fertility were observed in both the mutated populations and progeny of these selected partial sterile mutants showed unusual segregation behaviour. Progeny of mutants with above 90% pollen sterility were crossed with pigmented varieties to check female sterility also. Few mutants showed good results on pollen sterility, seed set percentage in selfed as well as crossed ear. Identified partial male sterile mutants need to be evaluated in next generations for higher percentage of sterility and their stability.
