Abstract:
This study aimed to find out best organic manure or manure combination for obtaining the maximum growth from okra, and to standardize the total NPK requirement through organic manures. 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 ten treatments, including a control T10 in a Randomised Complete Block Design (RCBD) that was replicated thrice. The combination of FYM, Vermicompost, Composted poultry manure and groundnut cake has been practiced in T5 to T9, and the other five treatments were based on different organic practices. The result showed that T₈ (90.26 cm) had a significant positive effect on plant height, while T7 (27.17) recorded the maximum number of leaves plant^-1 and T10 (33.0) for the minimum number of days to first flowering. Maximum dry matter production was reported in T10 (25.50 kg h^-1). While maximum leaf area index was noticed in T8 (3.71) during the rabi season of 2022.
