Abstract
A field experiment at Kakching, Manipur evaluated the effects of fish waste compost pellets, plant-based biopesticides and vermiwash on okra (Abelmoschus esculentus L. var. Arka Anamika) using a randomized block design with eleven treatments. Compost prepared from fish waste, sawdust, banana and jaggery was pelletized for easy application. The combined use of compost pellets and vermiwash significantly improved plant height, fruit length (12.56 cm), fruit diameter (3.6 cm), number of fruits per plant (22.5), individual fruit weight (12.40 g) and protein content (15.82%). Strong positive correlations (r = 0.742–0.928) were observed among yield traits. Overall, integrating compost pellets with vermiwash and botanicals proved effective for enhancing okra yield, quality and soil health.
