Abstract
A field experiment was conducted at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study on intercropping in Rabi castor (Ricinus communis L.) during Rabi season of 2017. Castor based intercropping systems found distinctly more productive than sole castor giving as higher additional yield advantage as 9519 kg/ha with 1 : 1 row ratio and 4498 kg/ha with 1 : 2 row ratio. Inclusion of marigold as intercrop increased total production per unit area per year. The total production potential in term of castor equivalent yield was maximum under castor + marigold 1:1 (5408 kg/ha) followed by castor + marigold 1:2 recorded 3998 kg/ha. Oil content (48.68 %) and oil yield (1465 kg/ha) of castor were also recorded higher under sole castor as compared to intercropped with marigold. castor + marigold at 1:2 row ratio gave higher land equivalent ratio (1.67) while the net return was greater when castor intercropped with marigold at 1:1 row ratio (₹ 155416/ha) followed by castor + marigold at 1:2 row ratio (₹ 94835/ha). The benefit: cost ratio was highest with castor + marigold in 1:1 row proportion (2.80) followed by sole castor (1.84) and sole marigold (1.79).
