International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Temporal and spatial variation in strip-cropping plants minimizes competition between them and increase yield, and profitability. It reduces soil loss from wind and water erosion and reduce mineral leaching losses. than most mono cropping operations (Cruse1990). With this view, to minimize the labor requirement and increase the profitability, the experiment was conducted to study the various strip cropping for soybean and pigeonpea crops under mechanization with suitable ratio and to work out the economics feasibility of the strip cropping under mechanization Methodology The field experiment was conducted in randomized block design with eight treatments and three replications at Research Farm, AICRP on Dryland Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif 2018-20 and 2021-22. The treatments were allotted randomly in each replication. The recommended dose of fertilizer was applied to crop. Soybean and pigeonpea were sown at 45 cm X 5 cm and 90 cm X 20 cm respectively. A complete seed to seed mechanization was done in the experiment. The treatments were T 1- soybean: pigeonpea strip of 6:3 rows, T2- soybean: pigeonpea strip of 6:6 rows, T3- soybean: pigeonpea strip of 12:9 rows , T 4- soybean: pigeonpea strip of 12:12 rows ,T 5- soybean: pigeonpea strip of 18:12 rows T6- soybean: pigeonpea (4:2) intercropping system , T7- Sole soybean and T8- Sole pigeon pea. Results Sole pigeon pea recorded significantly higher soybean equivalent yield (2366 kg/ha.) which was followed by soybean + pigeon pea strip of 18:12 rows (1973 Kg/ha) and soybean + pigeonpea strip of 12:12 rows (1918 Kg/ha). Highest gross monetary return (GMR) were recorded in sole pigeonpea (Rs. 87244 /ha) which was followed by soybean + pigeonpea strip of 18:12 rows and soybean + pigeonpea strip of 12:12 rows. Significantly highest net monetary returns (NMR) were observed in sole pigeonpea (Rs. 57589 /ha.) which was followed by soybean + pigeonpea strip of 18:12 row (Rs. 48075 /ha). Sole pigeonpea recorded highest rainwater use efficiency (3.8) and B: C ratio (2.6) followed by in the treatment of soybean + pigeonpea strip of 18:12 row. The increase in the monetary returns due to increased yield and saving in cost of operation because of mechanization in soybean and pigeon pea was reported by Dhakad and Khedkar (2014). Strip-cropping can improve yields, profit margins Ghosh (2004). Conclusion Sole pigeon pea recorded significantly higher soybean seed yield, GMR, NMR and RWUE, Whereas, soybean + pigeon pea strip of 18.9 m each (18 & 12 rows/strip) recorded significantly higher B:C ratio.
