Abstract: The experiment was conducted at Regional Agricultural Research Station, Warangal during kharif, 2013 to15 on redgram with an objective to study the effect of various management techniques experiment are seed treatment with Rhizobium + Pseudomonas bacteria + Plant growth promoting Rhizobium were common to all treatments except control (Farmers practice). viz; INM-integrated nutrient management (Vermi composting @ 2.5 t/ha + RDF i.e., 20 N, 50 P, 0 K, 50 S and 25 Zn kgha-1), IWM-integrated weed management (Pendimethalin 0.75 kg/ha on 3 days after sowing + Imazethapyr @ 100 g a.i ha-1 on 10-15 days after weeds emergence + one hand weeding on 50 days after sowing), IPM-integrated pest management (Indoxacarb 15.8% EC at the time of flowering @ 375 ml ha-1 + one systemic insecticide spray 15 days after 1st spray, INM + IWM, INM + IPM, IWM + IPM, INM + IWM + IPM and were compared with control (Farmers practice). The results revealed that INM + IWM + IPM recorded higher biometric characters, yield attributes (number of pods plant-1 (123.8), number of seeds pod-1(3.84), less number of borer infested pods plant-1 (4.27) and grain yield (1649 kgha-1) with higher soil organic carbon content (0.26 per cent) and available N (291.5 kg ha-1). The B:C ratio (1.64) was also recorded higher under the same treatment followed by INM + IWM and INM (grain yield 1327 kg ha-1 and 1230 kg ha-1, respectively); and were compared with control/farmers practice (1283 kg ha-1).
