Abstract

 

An investigation was carried out to know the effect of organics sources of nutrients on fruit damaged by shoot and fruit borer on brinjal (Solanum melongena L.). The results revealed that plots applied with Vermicompost (VC) + biofertilizer (Silica solubalising bacteria, Azatobactor and Vasicular Arbuscular Mycoriza) + neemcake (T6) and farm yard manure (FYM) + biofertilizer + neemcake (T5) were found to be effective and recorded minimum percent fruit damage (5.93 and 6.12%), with the corresponding percent reduction of 66.68 and 65.61 over NPK (T11). The next effective treatments were Vermicompost + biofertilizer + insecticide (T8) and FYM + biofertilizer + insecticide (T7), with percent reduction of 64.49 and 63.20 over NPK (T11), respectively. The minimum percent reduction was recorded in the treatments VC + biofertilizer + NPK (18.93%) and FYM + biofertilizer + NPK (17.75%) as against inorganic NPK.
