Abstract:

In order to evaluate the effects of sorghum and mungbean intercropping on yield, chlorophyll value and grain protein, an experiment conducted in 2013 at the Research Farm, Faculty of Agriculture, University of Tabriz, Tabriz, Iran, as randomized complete block design with seven treatments and three replications. The treatments were as follows: sole cropping of sorghum, sole cropping of mungbean and five intercropping patterns of sorghum: mungbean with replacement ratios ((1:1, 2:1, 3:1, 1:2, 1:3)) respectively. The results showed that the maximum chlorophyll index for sorghum and mungbean was obtained in intercropping treatments with (2:1) and (1:2) ratios. The maximum grain yield was achieved for both species in sole cropping treatments. Results indicated that different cropping patterns in all mixture treatments significantly gave higher grain protein content for both plants than monoculture treatments. Land Equivalent Ratio (LER) in all treatments were more than 1 and consequently, its recommended that sorghum and mungbean intercropping is better than monoculture.
