Abstract:
This study aimed to standardize non chemical methods of weed management and effects on growth of hybrid Okra. The study was conducted in the South farm of the School of Agricultural Sciences, Karunya Institute of Technology and Sciences, Coimbatore during the Rabi season of 2022. The experimental design consisted of seven treatments in a Randomised Complete Block Design (RCBD) that was duplicated thrice. Mulching with black LDPE is practiced in T₄ and intercropping with fodder cowpea is done in T5 and the other five treatments is based on different non chemical weed management practices. The result showed that T₂ (29.73 cm) had a significant positive effect on plant height, while T₄ (26.69) recorded the maximum number of leaves plant^-1 and T7 (72.87) for maximum number of days to first flowering and T₅ (5865 Kg ha^-1) recorded maximum dry matter production when compared to all the other treatments. Intercropping with fodder cowpea has shown positive effect on the weed control efficiency in T₅ (96.22%) during the rabi season of 2022.
