A field experiment was conducted during the Kharif season of 2022-23 to evaluate the Performance of Bt Cotton (Gossypium spp) and Pigeon pea (Cajanus cajan) under different resource conservation practices at experimental Central Farm Balsa, Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (M.S.). The soil of the experimental site was clayey in texture, soil pH of 8.2, low available N (193.28 kg ha^-1), medium in P₂O₅ (19.34 kg ha^-1) and high in K₂O (596.53 kg ha^-1). The experiment was laid out in split plot design with twelve treatment combinations consisting of six tillage practices T₁: Conservation tillage (one harrowing by tractor mounted blade harrow before sowing) (CnT), T₂: Conventional tillage (one ploughing + one harrowing by tyne cultivator + one harrowing by tractor mounted blade harrow) (CvT), T₃: Conventional tillage + Sub soiling (one sub-soiling + one ploughing + one harrowing by tyne cultivator + one harrowing by tractor mounted blade harrow) (CvTSS), T₄: Shallow tillage by tractor (one shallow tillage by tyne cultivator + one harrowing by blade harrow) (STT), T₅: Tillage by cultivator and rotavator (CRT), T₆: Shallow tillage by bullock (one shallow tillage by indigenous plough + one harrowing by bullock drawn blade harrow) (STB) and two treatment of crops C₁: Bt Cotton C₂: Pigeon pea. Results revealed that among the treatments, combination of tillage practices comprising of one sub-soiling + one ploughing + one harrowing by tyne cultivator+ one harrowing by tractor mounted blade harrow (T₃) with sole Bt. Cotton (Ajeet-155) recorded significantly greater seed cotton yield (kgha^-1), GMR, NMR and B:C ratio as compare to Pigeon pea (BDN-711) found productive and profitable at Parbhani location.
