Abstract:
A field experiment was conducted during Rabi 2022-2023 at Agricultural Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). The experiment was laid out in Randomized Block Design with seven treatments each replicated thrice on the basis of one year experimentation. The treatment consisted of recommended nutrient dose of 100:60:40, using organic sources i.e. FYM and Vermicompost, of different concentrations (100% RDN & 75% RDN), Acetobacter, PSB, and 4 foliar spray of 20% cow urine at 15 DAS interval, and 60 × 20 cm spacing was designated. The result showed that treatment 4 (100% RDN + Acetobacter +PSB + 4 foliar spray of 20% cow urine at 15 days interval) was recorded significantly higher plant height (188.13 cm), maximum number of leaves/plant (11.80). Whereas the maximum number of rows/cob (16.00), number of grains/row (34.47), number of grains/cob (541.60), cob length with husk (27.67 cm) and without husk (26.47 cm), cob weight with husk (363.89 g) and without husk (327.34 g), cob girth with husk (18.57 cm), cob girth without husk (15 cm), Green cob yield(13.36 t/ha) and green fodder yield (19.82 t/ha) as compared to other organic treatments.
