Abstract :

In order to investigate the effect of different concentration of mixed cropping of mung bean and corn on qualitative and quantitative aspects of forgave production; an experiment was performed in a fully randomized block design in natural resources and agricultural research center of Tehran province in summer of 2011. The experiment included treatments. Results showed that cropping of all mixed treatments at concentrations of 90000 and 110000 bushes per hectare for corn and 250000 and 350000 bushes. h for mung bean over pure cropping of the said plants at the aforesaid concentrations regarding LER (Land Equity Ratio) ranged from at least 1.27 (related to concentration of 110000 bushes/hector for corn and 250000 bushes/h for mung bean) to 2.94 (related to concentration of 90000 bushes/hectare for corn and 350000 bushes/h for mung bean).On the other hand investigation of queficients of dominance index in mixed treatments showed that corn crop was the dominant one in most of the treatments.Also results of function assessment of dry forages in highest level at T2 is 17.3 ton per hector and in lowest level in T4 is 1.2 ton. per hector and function of total wet forages at highest level at T2 is 77.3 ton. per hector and T4 in lowest level is 3.9 ton per hector. In total function of protein at highest level at T4 is 3.1 ton per hector and lowest level at T4 is 0.12 per hector.
