ABSTRACT
In an attempt to determine suitable organic package, stepwise combination of different compost, soil amendment and bio-inoculation of both seed and soil was considered. Combinations yielded in 8 treatments including recommended fertilizer dose in one of the popular cultivar of chilli (Beldanga Bullet) grown in the gangetic plains of West Bengal. Soil application of bio-inoculated vermicompost enriched by Trichoderma viride and phosphate solubilising bacteria Acenitobacter spp along with soil amendments with neem cake and seed dressing followed by seedling root-dip with Pseudomonas fluorescens followed by three spray of water soluble fertilizer N :P :K (19:19:19) was found best management practice in reduction of infestation of sucking pests such as thrips (72.57%), yellow mite (65.23%) and fruit borer (79.42%) in chilli. Moreover, it was found effective against leaf curl disease (18.33%) also. Thus a well-balanced organic protocol may produce quality product with less infestation of insects.
