In view of concerns raised about economic and ecological consequences of agricultural chemicals, organic amendments, such as vermiwash, have been considered appropriate strategies for crop improvement. However, research work evaluating the efficacy of foliar sprays of vermiwash in vegetable crops on acidic soils is quite limited. The present investigation, therefore, was carried out to evaluate the effect of different concentrations of vermiwash (VW) on okra (Abelmoschus esculentus L.) under field conditions on acidic soil. We also evaluated the response of Naga chilli (Capsicum assamicum) to foliar spray of 20% concentration of vermiwash. Results revealed that the application of VW significantly improved the vegetative and yield attributes of both the test crops. In okra, 20% VW exhibited the largest increase in marketable weight among all the treatments. The plants of Naga chilli receiving foliar spray of 20% VW registered a 27.47% increase in shoot height and a 11.93% increase in chlorophyll content (SPAD) as compared with control. In regards to yield attributes of the Naga chilli, foliar spray of 20% VW resulted in a 23.07 % increase (significant at P = 0.05) in number of seeds per fruit and a 43.47% increase (significant at P = 0.05) in average fruit weight in comparison with control. We suggest that foliar spray of 20% concentration of vermiwash could considerably improve the growth and yield of okra and Naga chilli on acidic soil.
