Abstract

Abstract
Density and crop ratio are two important factors for evaluating traits in legume/cereal intercropping systems. For this propose the effects of density and crop ratios in row intercropping on grain and biomass yield of grain sorghum, (promising line, M5) and common bean (Talash cultivar) were investigated. This experiment was laid out in growing season of 2007 in a randomized complete block design in factorial arrangment with 3 replications using response model. Treatments included 3 densities (low: 19.2, bean & 6.3 sorghum; medium: 38.4 bean & 12.8 sorghum and high: 59.17 bean & 25.6 sorghum plant in m2) and 5 planting ratios (33:67, 50:50, 67:33, 100:0 and 0:100 sorghum: bean). The analysis of variance carried out by bivariate analysis, and approach of skew axis was used for comparison of means. The results of bivariate analysis showed that effects of density in biomass and seeds number per plant was significant (p
