Impact of Vermicompost and Intercropping on Morphophysiological and Yield Performance of Sesame (Sesamum indicum L.)

Abstract— A field experiment was conducted at the Agricultural Farm, Himalayan University, Jollang, to investigate the Impact of Vermicompost and Intercropping on the Morphophysiological and Yield Performance of Sesame (Sesamum indicum L.). The study was laid out in a Randomized Block Design (RBD) with seven treatments replicated thrice. Sesame variety INDO US-5 and green gram variety KANIKA were evaluated at 30, 60, and 90 days after sowing (DAS). Among the treatments, T7 (100% RDF + Vermicompost 6 t/ha + Intercropping 2:2) consistently recorded superior results in terms of plant height (84.3 cm), number of leaves (67.6), number of branches (5.0), were observed during 60–90 DAS in T7. Moreover, T7 showed significant improvement in yield attributes such as capsule number (45.6), seed per capsule (38.6), capsule length (3.6 cm), test weight (3.7 g), biological yield (1.22 t/ha), and economic yield (0.46 t/ha). The highest harvest index (37.50%), were also recorded in T7. These results highlight the potential of integrated nutrient management and intercropping in enhancing sesame productivity and profitability.
