Evaluation of yield and advantage indices of sorghum (Sorghum bicolor L.) and mungbean (Vigna radiate L.) intercropping systems

Intercropping is considered for increasing and stability of yield per unit. In order to study the effects of different intercropping arrangements on sorghum and mungbean yield and to find the land use advantage in the intercropping system, an experiment was carried out based on a randomized complete block design with seven treatments and three replications at the Research Farm, Faculty of Agriculture, University of Tabriz in 2013. The treatments were as follows: sole cropping of sorghum, sole cropping of mung bean 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 grain yield was obtained from both species in monoculture treatment. The highest intercropping advantage (3.22) was related to treatment (1:3). Also, the highest value of RYT was observed 1.36 in treatment (1:1). Land equivalent ratio (LER) in all evaluated treatments was more than one. Thus, according to economic evaluation indices, sorghum and mungbean intercropping was economically justified in comparison with their sole cropping in Tabriz.
