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.
