Studies on effect of vermitechnologies on insect-pest activity and yield of soybean

A field experiment was conducted at the University of Agricultural Sciences, Dharwad, Karnataka, during Kharif 2007 to study the effect of vermicompost and vermiwash on the activity defoliator pests, pod borer and yield attributes of soybean. The results indicated that application of vermicompost @ (2 t/ha) and split application of vermicompost (2 t/ha + four vermiwash (1:3) sprays were effective in reducing the incidence of defoliators and pod borer, being comparable to RPP. Significantly highest seed yield was registered in the treatments receiving vermicompost @ 3 t/ha + four sprays of vermiwash (1:5) (30.00 q/ha) and vermicompost @ 1 t/ha + four sprays of vermiwash (1:1) (25.83 q/ha) which were on par with each other, were comparable to RPP (30.80q/ha). Untreated crop yielded significantly lowest yield at 10.58 q/ha.
