INTERCROPPING OF RAPESEED (BRASSICA-CAMPESTRIS SUBSP OLEIFERA VAR TORIA) WITH NIGER (GUIZOTIA-ABYSSINICA) UNDER RAIN-FED CONDITION

An experiment was conducted during the winter (rabi) season of 1991-92 and 1992-93 at Shillongani, to find out the suitable combination of r apeseed [Brassica campestris L. spp oleifera (Metzer) Sinsk. var. tori a] and niger (Guizotia abyssinica Cass.) intercropping system. The yie ld-attributing characters of all intercropping combinations and pure c rops were not significant. Yield of both the crops gradually increased with an increase in row proportion and decreased with decrease in pro portions. However, the highest values of rapeseed-equivalent yield (9. 25 q/ha), land-equivalent ratio (1.30), monetary advantage (Rs 1,707.8 1), net return (Rs 4,025.50/ha) and net return per rupee invested (Rs 1.19) were recorded in 2 rapeseed : 2 niger combination in comparison to the pure crops and other combinations.
