Effect of minimum tillage on productivity and economics of sweet corn: Pulses intercropping system

Abstract

Field experiment was carried out at Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, and Akola (M.S.) during kharif 2013 to study the effect of minimum tillage on productivity and economics of sweet corn - pulses intercropping system in FRBD with four replication. The main plot treatment viz., S1- Conventional tillage (one Ploughing and two harrowing), S2- Minimum tillage (one harrowing) and three sub-plot treatment of intercropping I1- Sole sweet corn, I2- Sweet corn+ Green gram (1:2 ratio), I3- Sweet corn + Black gram (1:2 ratio). The result revealed that conventional tillage treatment recorded higher number of cob ha-1, biological yield, harvest index, GMR (186507 ₹ ha-1), NMR (148159 ₹ ha-1), and B: C ratio (4.96) than minimum tillage and among intercropping treatments sweet corn + black gram recorded highest GMR (194698 ₹ ha-1), NMR (157467 ₹ ha-1), B: C ratio (5.23) followed by treatment sweet corn + green gram.
