Epidemiological Analysis of Weather Parameters on Leaf Spot and Flower Blight (Alternaria tagetica) Disease in Marigold cultivation under North Western Himalayan Region

Paper ID- AMA-10-01-2024-12830

Floriculture has emerged as a lucrative source of income for farmers and is experiencing significant growth in the Jammu Valley of the North Western Himalayan region. Marigold (Tagetes erecta L.) stands out as a major ornamental crop cultivated in agro-climatically diverse areas, subjecting the plants to various abiotic and biotic stresses. Among these stressors, leaf spot and flower blight caused by Alternaria tagetica pose a substantial economic threat. Therefore, conducting periodic surveys to assess disease incidence and severity becomes imperative. Fortnightly surveys were carried out in key marigold-growing areas of Jammu, including Jammu, RS Pura, Bishnah, and Akhnoor block in Jammu district. The findings revealed an average disease incidence of 49.90% and 49.40% during the years 2017-18 and 2018-19, respectively. The impact of plant age on disease progression indicated that maximum leaf spot severity reached 57.50% and 58% in 2017-18 and 2018-19, respectively. Similarly, the maximum flower blight incidence recorded was 43.75% and 43.60% during the same periods, highlighting a correlation between disease development and plant age. The study underscored the significant role of environmental parameters—temperature, relative humidity, and rainfall—in disease development. During 2017-18, these parameters accounted for 51.0% and 94.2% influence on leaf spot and flower blight disease, respectively. In 2018-19, the respective percentages were 71.1% and 92.9%, confirming the impact of environmental factors on disease dynamics. The field experiment further validated these findings on the susceptible cultivar Pusa Basanti. Understanding these dynamics is crucial for developing effective strategies to mitigate the economic losses caused by leaf spot and flower blight in marigold cultivation in the North Western Himalayas.

Effectiveness of Farmers Fair in Transfer of Technology: A study in GBPUA&T, Pantnagar

Paper ID- AMA-07-01-2024-12825

Farmers fair also popularly known as ‘Kisan Mela’ are in subsistence for a long time. The main purpose of organizing such an event is to create awareness among the visitors about new technologies developed by researchers, primarily from the Government sector, agricultural and allied research centers, and State Agricultural Universities. In recent years, farmers' fairs have emerged as crucial instruments for disseminating cutting-edge agricultural technologies to farmers. The primary objective behind organizing these events is to raise awareness among attendees about the latest technologies developed by researchers, predominantly from the government sector, agricultural and allied research centers, and State Agricultural Universities (SAUs). Farmers fair also helps farmers in enhancing their knowledge of new schemes or programs. The study was undertaken to know the perception of farmers about usefulness of farmers fair. The study was conducted at G.B. Pant University of Agriculture & Technology, Pantnagar, involving 120 randomly selected farmers visiting the fair. The findings indicated that a good majority of participating farmers perceived that information received at Kisan Mela on Agricultural implements and machines, seed storage and processing, high yielding seed varieties, information on fertilizers, mushroom cultivation, dairy and animal husbandry, irrigation method and organic farming was highly useful.

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.
