Castor is a valuable non-edible oilseed crop palying an important role in agricultural economy. It is ideally suited for intercropping system, as currently a number of short duration, wilt tolerant/varieties/hybrids are available. Castor was evaluated as a component crop in various legume and non-leguminous crops in 6: 1 and 10: 1 row proportions under rainfed conditions. Intercropping of blackgram with castor in 6: 1 row porportions resulted in the highest LER value of 1.85 coupled with highest yield of castor. Studies also elucidated that there was reductions in the incidence of semilooper and wilt on castor in castor and pigeonpea intercropping system, while castor+sesame aggrevated the situation of semilooper and wilt in comparison with sole castor crop.
