The document discusses oilseed crops intercropping in India. It provides background on major oilseed crops grown in the country like soybean, groundnut, mustard, sesame, etc. Intercropping systems studied include castor-based, groundnut-based, and sesame-based intercrops. The advantages of intercropping include yield stability, efficient resource use, and higher total productivity per unit land area. Research findings show castor-groundnut and castor-clusterbean intercropping systems providing higher castor equivalent yields, land equivalent ratios, and economic returns compared to sole castor.
