Abstract:
The constraints in the production of sunflower crop were identified with a major emphasizes against the pest and diseases in the sunflower. The critical inputs required were identified from the recommended package of practices of Karnataka and their usages were discussed in practicing farmer's trainings at the farmer's field. The average five years data revealed that an average yield of demonstrated plot was obtained 14.99q/ha over local check 13.23 q/ha and the average percentage increase in yield over local check was 12.33 per cent. The average extension gap was found to be 0.95. The hybrid RSFH –1887 and KBSH-53 performed better at front line demonstrated plot as compared to local check. Further, benefit: cost ratio was recorded to be higher under demonstrated plot against local check during the study. Further, average higher benefit- cost ratio (1.77) was recorded under demonstrated plot against check (1.53). The results clearly indicate the positive effects of FLDs over the existing practices towards enhancing the yield of the sunflower hybrids. Findings of the study clearly indicate the positive effects of FLDs over the existing practices towards enhancing the yield of the sunflower hybrids.
