Field Experiment to validate the Biointensive IPM (BIPM) package on black rice variety “Kola Chaul” revealed that BIPM package consisting seedlings root dip with Pseudomonas fluorescens @ 2% solution; application of organic manure MUKTA @ 2 t ha-1; application of Beauveria bassiana @ 1013 spores ha-1 against sucking pests, use of bird perch (10 ha-1), 6 releases of Trichogramma japonicum @ 50,000 ha-1 at 10 days interval starting from 30 days after treatment (DAT) for stem borer and leaf folder infestation along with need based application of botanicals NSKE 5% (5 l/l-1) could suppress the major rice pests and produce higher grain yield as compared to the farmer’s practice (FP). Maximum grain yield of 3124.8 kg ha-1 and 3139.10 kg ha-1 was recorded in BIPM field as compared to 2882.6 kg ha-1 and 2897.20 kg ha-1 in farmers practice plot during 2020-21 and 2021-22, respectively. Thus, BIPM practice was observed to be superior to FP with higher benefit: cost ratio.
