The experiment was carried out at the Instructional cum Research Farm, Department of Horticulture, Biswanath College of Agriculture, AAU, Biswanath Chariali during 2022-2023 to study the effect of organics on yield and quality of okra and to find out the most profitable organic nutrient treatment. The experiment was laid out in randomized block design with 3 replications incorporating 16 treatments viz., T1: FYM @20 t ha-1, T2: vermicompost @ 5 t ha-1, T3: neem cake @ 2 t ha-1, T4: poultry manure @ 5 t ha-1, T5: FYM @ 10 t ha-1 + vermicompost @ 2.5 t ha-1, T6: FYM @ 10 t ha-1 + neem cake @ 1 t ha-1, T7: FYM @ 10 t ha-1 + poultry manure @ 2.5 t ha-1, T8: vermicompost @ 2.5 t ha-1 + neem cake @ 1 t ha-1, T9: vermicompost @ 2.5 t ha-1 + poultry manure @ 2.5 t ha-1, T10: neem cake @ 1 t ha-1 + poultry manure @ 2.5 t ha-1, T11: FYM @ 10 t ha-1 + biofertilizer consortia, T12: vermicompost @ 2.5 t ha-1 + biofertilizer consortia, T13: neem cake @ 1 t ha-1 + biofertilizer consortia, T14: poultry manure @ 2.5 t ha-1 + biofertilizer consortia, T15: FYM @ 10 t ha-1 + recommended NPK and T16: untreated control. Significant variation was observed in the fruit yield related parameters as well as quality parameters. The maximum number of fruits per plant (18.99), fruit length (14.10 cm), fruit girth (6.55 cm), fruit volume (18.42 cc), the weight of individual fruit (15.71 g), fruit yield per plant (0.29 kg) and yield per hectare were recorded in treatment T1. However, the fruit yield per hectare was significantly higher in inorganic treatment T15 (14.12 t ha-1). Among all the treatments the highest vitamin A (375.06 I.U) and vitamin C (29.00 mg 100 g-1) were recorded in organic treatment T5 and minimum fibre content was recorded in T12 (9.76%). Considering the highest B:C ratio (2.53:1) and with superiority among the organic treatments, it could be suggested to the growers of this region to apply FYM @ 20 t ha-1 in okra to get a good crop harvest with quality fruit.
