ABSTRACT

The continuoususe of inorganic fertilizers over a period of time cannot sustain the cropyield for a long time, in view of their harmful effects on soil aggregation,and poor root anchorage for normal nutrient and moisture uptake. The organicmanures play an important role in supplying macro and micronutrients andimprove the physical, chemical and biological property of the soil. The presentstudy was undertaken to study the effect of organic nutrients supplementingthrough foliar spray of panchakavya (5 and 10%), vermiwash (10 and 15%) and seriboost(0.2%) on 15, 25 and 35 days after pruning following basal doses of vermicompostand inorganic fertilizers in normal recommendation in mulberry garden. Thetreatment of panchakavya and vermiwash showed better performance in mulberrygrowth parameter viz., number of shoots/plant, total biomass and leafyield. The average incidence of pest tukra mealy bug Maconellicoccushirsutus (Green), Pseudodendrothrips mori, leaf webber D.pulverulentalis were minimum in the treatment of panchakavya and vermiwash.On the food consumption and utilization of Bombyx mori L. larvae (CSR2 xCSR4) fed on leaves treated with panchakavya, vermiwash and seriboost revealedthat with advancing instars, irrespective of the treatment food consumption increased,but the pattern of food consumption differed significantly. The rate of feeding(Cr), Assimilation (Ar), and production (Pr) were higher in larvae treated withpanchakavya (10%) and vermiwash (15%), over control. The assimilationefficiency and larval growth of the larvae fed on leaves treated withpanchakavya, vermiwash and Seriboost increased over control.
