Abstract

A field experiment was conducted during 1987-88 to 199C-91 on silty-loam soil to select a suitable rainy-season crop for intercropping with castor (Ricinus commu~~is L.). The highest mean castor- equivalent seed yield (25.16 qha), land-equivalent ratio (1.43). net return (Rs 12,995ha) and monetary advantage (Rs 39.07ha) were obtained by intercropping 2 rows of greengram (Phareolus rudiafus L.) in between the castor crop sown at 1 m row spacing. This was followed by castor + blackgram (P. mungo L.) (2 rows) and castor + groundnut (Arachis hypogaea L.) (2 rows).
