Study on intercropping of castor, Ricinus communis L. under irrigated condition

Castor and companion crops were sown at 120 cm x 60 cm row x plant spacing respectively at Mandor, Rajasthan. The castor yield was not reduced significantly by raising intercrops. Sole castor produced maximum seed yield of 3694 kg/ha closely followed by castor + greengram 1:1, castor + moth bean 1:1. The castor seed equivalent yield recorded with castor + greengram 1:1 (4531 kg/ha) was 837 kg/ha higheroversole castor. Corresponding increase due to castor + moth bean 1:2 system was 639 kg/ha. Castor + sesame intercropping system in 1:1 and 1:2 ratios was notfound effective as seed equivalent yield, net return and B:C ratio were not influenced remarkably due to adoption of this system.
