Assessment of Training needs of diverse Agripreneurs in India: Mean Weighted Discrepancy Score Approach

Paper ID- AMA-06-01-2024-12824

Agriculture sector contributes to nutrition security and acts as a steady medium of income generation. In case of horticulture crops, marginal fragmented lands are utilized which otherwise cannot be used for other demanding crops. Despite of high demands, tremendous scope and opportunities in the field, established industries are somehow limited which raises an issue of sustainability of these agripreneurs. A need emerges to classify and comprehend the training needs of agripreneurs to enhance the skill and productivity in the region. The study was conducted in Kumaon Division of Uttarakhand where Nainital and Almora districts were selected purposively. Total 70 agripreneurs were selected through snowball sampling method. A semi-structured interview schedule was used for data collection. Descriptive research design was used to meet the objectives of the study. The study showed that respondents had low level of information-seeking behavior (42.86%), medium level of innovativeness (57.14%), risk-taking ability (57.14%), and achievement motivation (60%). A whooping number of respondents hold micro-scale enterprises (97.14%). They had low levels of entrepreneurial experience (55.71) and had low institutional support (84.28%). Regarding the training needs of agripreneurs, it was found that the majority of respondents had maximum training needs in value addition and processing in mushrooms and vegetable production. Present study also revealed that there was least use of extension education methods among respondents that clearly indicated the limited contacts of agripreneurs from personal cosmopolites and extension help for which future dimensions of extension help needs to be opened in the sector.

In vitro chromosome doubling potential of colchicine and oryzalin for the production of doubled haploid plants in marigold (Tagetes erecta L.).

Paper ID- AMA-03-01-2024-12818

An effective chromosome doubling protocol was developed in African marigold (Tagetes erecta L.) Cv. Local Orange. The different concentrations of colchicine (50, 75 and 100 mg/L), oryzalin (50, 75 and 100mg/L) and the combination of the two above mentioned anti-mitotic agents (50 and 75mg/L) was used on anther derived haploid nodal segments/explant of marigold for different durations (18 and 38 hours for each concentration). Based on the results obtained, highest percent diploidized shoots (75.40% and 64.80%) was found in experiments where nodal segments were treated with oryzalin @ 50mg/L for 38 hrs and colchicine @ 100mg/L for 38 hours respectively. In case of combination highest percent diploidized shoots was 54.4% which was found with colchicine plus oryzalin @ 75mg/L of each for 38 hours. However, the highest survival of shoots was found in control (no chemical treatment) in all the three categories. Increasing the concentrations of applied antimitotic agents led to the significant reduction in the survival rate of nodal explants, especially when the explants were exposed for longer durations.

Optimizing bio-organic preparations and Sharbati wheat varieties for higher organic wheat productivity and profitability

Paper ID- AMA-01-01-2024-12814

In JNKVV, Jabalpur, a research was conducted to examine the effects of biodynamic preparations in the context of comparisons of conventional, organic, and biodynamic systems and varied varieties of wheat. Seven BOP (bio-organic preparations) served as the treatments of main plot for the experiment's split plot design, while four different wheat varieties served as the sub plot treatments, each of which was replicated thrice. Observations based on plant population, various crop’s growth studies were noted at the 30, 60, 90 DAS and at the harvest. However, the crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) was computed at 30-60 and 60-90 days intervals. The yield attributing characteristics viz., length of ear head, number of effective tillers per meter square, no. of grains per ear head, weight of grains per ear head, and the test weight and finally grain and straw’s yield were recorded at harvest. Finally, the economic viability of treatments were determined in the terms of gross monetary returns, cost cultivation, net monetary returns and benefit- cost BC ratio on the per hectare area basis. Data pertaining to the various parameters subjected to the statistical analysis for the interpretation of the results. The combined application of BD500+BD501+P+VC was succeeded by P+VC and BD500+BD501+VC, gave a notable increase of 22.29, 18.26, and 6.38 per cent on grain yield of wheat over the sole application of BD500, BD501, and P each with VC. Considerably higher grain (2462.18 kg per ha) and straw yields (3149.88 kg per ha), including harvest index (HI) (43.73). In terms of profitability, BD500+BD501+P+VC was superior to BD: 500+BD: 501+VC and P+VC. Aside from that, it was noted that the use of BD-500+BD-501 or P+VC in JW-3020 and HW-2004 as well as BD500+BD-01+P or P+VC in C-306 and Sujata stood more lucrative.

Evaluation of serum Lipid profile, immunity, caecal microbial load and egg sensory attributes of Japanese quails fed with holy basil (Ocimum sanctum Linn) and curry leaves (Murraya koenigii L), either singly or in combination

Paper ID- AMA-27-12-2023-12808

An experiment was carried out for six weeks using eight weeks old one hundred eighty white feathered laying quails (Coturnix coturnix japonica) to study their production performance, egg quality and egg yolk cholesterol. The experiment was conducted following 2 x 3 factorial CRD wherein two herbs (holy basil and curry leaves) were fed to laying quails each at three dietary levels (0, 1 and 3%) of holy basil and curry leaves of 0, 2.5 and 5% in combination. All the laying quails were distributed randomly into nine dietary treatment groups (T1 to T9) on the basis of similar egg production and body weight. Each treatment has five replications containing four birds/replication. A standard corn-soya meal based basal diet to meet NRC (1994) standard for laying quails was formulated. From the basal diet as maintained above, nine experimental diets (designated as T1 through T9) were formulated by adding desired levels of Holy basil (HB) leave powder and Curry leaves (CL) powder. Birds fed 3% holy and curry leaves at 5% had significantly (P<0.001) reduced liver cholesterol level. Holy basil at 3% level and Curry leaves dietary addition at 5% level had shown significant effect on serum lipid parameters, HA titre and Caecal microbial count. The study revealed that both holy basil and curry leave powder inclusion in the Japanese quail diet have reduced liver cholesterol content, Serum cholesterol level, induce immune response and reduced intestinal pathogenic microbes and improve the beneficial microbial population.

Traditional Chinese Medicine Library: Molecular docking and Molecular dynamic simulation studies of compounds targeting Prototheca spp. a microalgal pathogen of zoonotic importance

Paper ID- AMA-25-12-2023-12801

Protothecosis, a zoonotic algal infection needs to be addressed under the one health principles. Treatment of algal infections has always been a challenge. There is no specific treatment for protothecosis both in humans and animals. Currently the only treatment for humans and food animals are antifungals which is associated with risk of toxicity and emergence of resistance. This study was aimed at identifying compounds for the control of Protothecosis by conducting insilico analysis against sterol 14α-demethylase (CYP51/ERG11), a key enzyme involved in the biosynthesis of ergosterol in Prototheca Spp. Traditional Chinese Medicine (TCM) library present in Drugrep was used for selecting the top hits and the ligands were ranked based on predicted affinity and molecular dynamics (MD) simulations was conducted using GROMACS2021 package for a timescale of 30ns. Based on autodock Vina affinity score/X-Score Binding energy of six compounds from Drugrep, that scored above -9.0 Kcal/mol and did not violate Lipinski’s rule of five criteria were selected: Peimisine, Limonin, Hecogenin, Jervine,((25R)-Spirost-4-ene-3,12-dione), Cyclopamine and Obacunone. The MD results showed that the (25R)-Spirost-4-ene-3,12-dione) had the most stable root mean square deviation (RMSD) when bound to sterol 14α-demethylase. However, the root mean square fluctuation (RMSF) of the protein both in bound and unbound state was similar. Ligands Hecogenin and (25R)-Spirost-4-ene-3,12-dione) that had 3-4 and 1 hydrogen bonds, respectively showed fewer fluctuations as compared to others. These two predicted compounds the (25R)-Spirost-4-ene-3,12-dione) and Hecogenin could possibly be expanded for their potential as drug candidates against Prototheca spp.
