maintaining soil fertility. The initial slow growth rate and deep root system of pigeon
pea offers a good scope for intercropping with fast growing early maturing and shallow
rooted crops. Considering these points an experiment was conducted to evaluate
comparative performance of the pigeon pea based intercropping system.
Methodology
The field evaluation of pigeonpea base intercropping systems was carried out on at the Dry
Farming Research Station, Solapur (MS) with an objective to study the production potential
and economics of pigeonpea based inter cropping systems under rainfed condition. The
experiment was conducted for three consecutive years during kharif seasons of 2015-16 to
2017-18. The experimental soil was low in available N (138 kg/ha), medium in available P2O5
(10.23 kg/ ha) and higher in available K 2O (454 kg/ha). The organic carbon content was low
(0.38%) with pH (7.84) and electrical conductivity of 0.17dS/m. The experiment was laid out
in randomized block design with three replications. In all, 9 treatments comprising five sole
crops viz. pigeonpea, clusterbean, soybean, pearl millet, sunflower and four intercropping
systems viz. pigeonpea + clusterbean (1:5), pigeonpea + soybean (1:5), pigeonpea
+pearlmillet(1:3) and pigeonpea+ sunflower(1:3). The crops were given the recommended
fertilizer dose and raised with recommended agronomic practices of MPKV Rahuri.
Results
The result revealed that, the yield of different crops in intercrops was influenced significantly
by different treatments (Table). Higher yield under sole crops was recorded under sole soybean.
While pigeonpea grain yield in association with different intercropping ranged between 610 to
741 kg/ha and 1146 to 1347 kg/ha grain and straw yield, respectively. The pigeonpea grain
equivalent yield (1637 kg/ha) was significantly higher in pigeonpea + sunflower 1:2
intercropping system. While, pigeonpea + soybean (1:5) was second in order. Among the sole
crops highest yield of 1862 kg/ha was recorded in sunflower. The highest LER (1.57) was
observed in pigeonpea + sunflower (1:3) intercropping system followed by pigeon pea +
soybean (1:5) was observed in intercropping system. Economic analysis revealed that the
intercropping in pigeonpea + sunflower (1:3) recorded maximum gross monetary returns
Rs.73,674/ha and Net Monetary returns Rs.30,872/ha and B:C ratio (1.72) followed by sole
sunflower with gross monetary returns Rs.53706/ha and net monetary returns Rs.21141/ha and
B:C ratio (1.65).
