Study of Vermicompost and Vermiwash Produced from Cow Manure and Rice Bran Waste on the Physiological Growth of Abelmoschus Esculentus L.

Vermicomposting is a cost-effective and eco-friendly process used to treat organic waste.Vermicompost is nutrient rich organic compost with active microorganisms resulting from the interaction between earthworm and microorganisms on the breakdown of organic matter.Earthworms convert the waste material in to small particles by breaking in the gut of earth worm obtaining nutrients from the microbes that harbor on them.These processes increase the rate of degradation of the organic waste matter, modify the physico-chemical properties of the waste materials and forms humus in which unstable waste matter is completely oxidized.Vermiwash is a biofertilizer that enhances growth in Okra plants.Vermiwash was extracted from vermicompost composted from rice bran through earthworms (Eisenia foetida).It was observed that treatment of vermiwash significantly increased the growth of Okra plants.The significant growth was observed in okra plant height 89.66±1.3cm.This study showed that combination of organic fertilizers, Vermicompost and vermiwash when compared with control greatly influenced okra plants growth parameters.Among the five treatments, Treatment T 3 (Soil + vermicompost + 1 / 2 recommended dose of NPK) was most effective for all growth parameters of okra.In the present study vermicompost and vermiwash are a plant growth promoting organic fertilizers that efficiently improve the growth of okra.
