The gap between actual and potential crop production can be minimized by maintaining plant health, which needs crop-specific technology interventions. On-farm trials were conducted during 2017-18 and 2018-19 in the farmers’ fields in the Sundarbans to study the impact of crop-specific technologies on crop yields. The yield of mustard can be increased by about 47% with the installation of A. mellifera bee hives @ 3 ha-1 while it was about 40% in the case of A. cerena type @ 5 ha-1. A considerable increase (30.17% and 20.90%) in pod setting was recorded via the installation of mellifera bee hive and cerena type, respectively. Spraying of panchagavya @ 5%, sasyagavya @ 5%, and dasaparni @ 1% at 30 days after sowing (DAS) onwards at 15 days intervals, alternate application with 600 L ha-1 of jeevamrit as soil application at 30 DAS boosted the plant growth attributing characters in black gram. The same treatment recorded the highest yield of black gram (0.95 t ha-1), lowest infestation of pod borer (8.6%) and lowest powdery mildew infestation (21.20%). Application of beejamrit for seed bio-priming and 5% jeevamrit at 30 and 45 DAS as spray and soil application @ 600 L ha-1 also showed potential results with 30% increased yield of black gram over existing farmers’ practices. The integrated approach consisting of the application of T. viride enriched cow dung @ 750 kg ha-1, seed treatment with carboxin 17.5% + thiram 17.5% @ 3 mL kg-1 seed, installation of pheromone trap @ 30 ha-1 and need-based spot application of neemastra @ 3% resulted in highest seed yield of green gram (0.94 t ha-1) and B:C ratio (3.38) followed by chemical management (0.93 t ha-1, 3.23).
