Potancy of Vermiwash with Neem Plant Parts on the Infestation of Earias vittella (Fabricius) and Productivity of Okra (Abelmoschus esculentus) (L.)

Okra (Abelmoschus esculentus) is a popular and worldwide commercially cultivated vegetable crop. Abundant use of chemicals in agriculture for the productions of vegetable leads to concentration on plant and soil. The municipal solid wastes (MSW) caused environmental hazards and various adverse effects on ecosystem, if proper management is not available. There was recycling of MSW through vermibiotechnology and vermiwash production. The aim of present study was to determine the effect of vermiwash with neem plant parts on the germination, growth, productivity of okra and its pest infestation. The significance germination of okra seed in vermiwash with aqueous extract of neem bark (VW+NB) 97±5.21% than other combinations and early germination was observed (11.48±0.49 days). The maximum height of okra 42.42±0.79 cm was observed in after 90 days by sprays of VW+NB. The combination of VW+NF was important for high productivity of okra. The maximum productivity of okra plant was observed 773.23±20.64 g/m2 in treated with VW+NF. The lowest pest infestation of okra pod borer ( Earias vittella ) was observed after spray by VW+NF combination.
