The field experiment was conducted during 2007–08 and 2008–09 in Meerut district on sandy loam soil. The mean results of two years revealed that the highest values of all the yield attributes were observed in wheat grown after urdbean. Statistically the highest grain yield of wheat was observed after urddbean (45.5 q/ha) which was closely followed be grown after mungbean (45.3 q/ha). Significantly higher wheat grain equivalent yield of 102.1 q/ha was obtained under sorghum-urdbean-wheat cropping system whereasthe lowest wheat grain equivalent yield was noted in sorghum-wheat (77.9 q/ha). On the basis of economic analysis, sorghum-urdbean-wheat cropping system gave the maximum net return (Rs. 89,708/ha) followed be sorghum-mungbean-wheat (Rs. 86,919/ha), rice-wheat (Rs. 79,600/ha) and urdbean-wheat (Rs. 77,488/ha). Statistically the lowest benefit: cost ratio obtained with rice-wheat (2.22) which was significantly lower than other cropping system except sorghum-wheat. Whereas, the highest benefit: cost ratio obtained with urdbean-wheat (3.34) cropping system.
