Effect of row ratio in cereal-legume intercropping systems on productivityand competition functions under Kashmir conditions

A study was undertaken during rainy season 1995 and 1996 at Shalimar campus on silty clay-loam soils to assess the effect of various row ratios on pro ductivity and competition functions in cereal-legume intercropping system. The intercropping of maize (Zea mays L.) with field bean (Phaseolus vulgari s L.) in a row ratio of 1:2 recorded maximum land-equivalent ratio (1.61), area-time equivalent ratio (1.48), monetary advantage index (Rs, 19,202/ha) and aggressivity index (0.69), resulting in significantly highest maize eq uivalent (78.8) q/ha) along with yield attributes among all intercropping s ystems. This intercropping system also proved profitable with highest benef it: cost ratio (1.87).
