Abstract
In semi-arid areas, fodder oats (Avena sativa L.) are an essential crop for sustainable livestock production, especially for small and marginal farmers in the Hanumangarh district of Rajasthan, India. Through Frontline Demonstrations (FLDs) carried out by Krishi Vigyan Kendra (KVK) Nohar in a number of locations around the Hanumangarh district, this study assessed the performance of the enhanced oat variety Central Oat OS 403. During two consecutive rabi seasons (2022-23 and 2023-24), thirty FLDs were planted across 3.0 hectares in order to evaluate the economic viability, technological gaps, and varietal performance under farmers' field circumstances. The objective of this study is to find high-performing fodder cultivars, enhance agricultural methods, and provide farmers in Nohar, Hanumangarh district, with training to increase fodder output and sustainability. Results revealed superior performance of OS 403 with an average green fodder yield of 411 q/ha compared to 360 q/ha under farmers' practice, representing a significant yield advantage of 51 q/ha (14.17% increase). The technology gap was recorded at 51 q/ha, while the extension gap stood at 123 q/ha, resulting in a technology index of 9.53%, indicating good technology transfer efficiency. Economic analysis demonstrated the profitability of improved variety, with OS 403 generating a net return of Rs. 71,445/ha and benefit-cost ratio of 4.10, compared to Rs. 60,800/ha net return and benefit cost ratio (BCR) of 3.76 under local practices. The enhanced variety's economic superiority was demonstrated by the Rs. 10,645/ha higher revenue it generated. The study unequivocally shows that Central Oat OS 403 is suited to the semi-arid climate of the Hanumangarh district and has a great deal of promise for raising livestock nutrition, fodder production, and farmer revenue. These results lend credence to the suggestion that OS 403 be widely adopted by successful extension initiatives in Rajasthan's comparable agroclimatic zones.
