Influence of Organic Manures and Inorganic Fertilizers on Growth, Yield and Quality of Okra (Abelmoschus esculentus L.) cv. TMOH-2366

The study was planned to see the influence of different organic manures and inorganic fertilizers on growth, yield and quality of okra which comprised the combination of organic manures (FYM, neem cake, vermicompost) and inorganic fertilizers (viz., Nitrogen, Phosphorus and Potassium). The experiment was laid out in RBD with 9 treatments with 3 replications. Treatments involved were T0 – 100% RDF + 20 t/ha FYM, T1 – 100% RDF + 10t vermicompost, T2 – 100% RDF + 2t neem cake, T3 –75% RDF + 25% FYM, T4 – 75% RDF + 25% vermicompost, T5 – 50% RDF + 50% neem cake, T6 –50% RDF + 50% FYM, T7 – 50% RDF + 50% vermicompost, T8 – 50% RDF +50% neem cake. The results revealed that T1 (100% through RDF + 10t vermicompost) performed the best in term in days to germination (9.20 DAS), days to emergence (19.87 DAS), days to 50% flowering (49.20 DAS), plant height (75.03 cm), days to first harvest (56 DAS), number of fruits per plant (10), fruit length for marketability (10.71 cm), average fruit weight for 10 capsule (109 g), fruit yield per plant (194.93 g), fruit yield per hectare (116.96 q/ha), total soluble solids (5.80° Brix), ascorbic acid (18.54 mg/100 g), fruit colour (138.33) and B:C ratio (2.81). Therefore, the treatment T1 (100% through RDF + 10t vermicompost) is the best when compared to all other treatments. As the highest benefit cost ratio, net return and gross return was observed in T1 (100% RDF + 10t vermicompost) i.e., (2.81), Rs. 226422 and Rs. 350880 which states that it is economically profitable compared to all other treatments.
