To comparison of different growth analyse indices for Vigna and Tepary Jiroft, Iran local beans germplasms in various plant densities in 2009 this experiment was conduct. The research was done on farm of Jiroft Islamic Azad University research farms, Jiroft, Iran. The experiment was performed in split plot in basis of RCBD with 4 replications. The treatments were considered three plant density as main plots and three tropical bean genotypes include Jiroft local vigna, cream and black colour tepary beans as sub plots. The various plant densities were 400, 200 and 133 thousand plant per hectare. In order to evaluating growth changes process the rate of accumulation of dry matter, relative growth rate, crop growth rate, leaf area index and net absorption rate were measured. Results indicated that the highest TDM was related to vigna with 330 gr/m2 and the least TDM was related to the black tepary bean with 277gr/m2. The highest records of LAI and CGR observed in cream colour tepary bean and the highest rate of TDM, LAI (4.5), RGR and CGR observed in density of 400 thousand plants per hectare. The highest rate of NAR was in density of 133 thousand plants per hectare.

In this study the yield and yield component ofCowpea and Tepary local beans germplasme in various plant densities were evaluated. Experiments were done in 2009 in research farm of Jiroft Islamic Azad University, Iran. The farm experiment was performed in form of split plot based on RCBD with four replications. The treatments were consist three plant density levels as the main factor and three tropical bean genotypes (The Jiroft local cowpea, the cream colour tepary bean mass and the black colour tepary bean mass) as sub factors. The various plant densities performed by regularization distance between plants on rows (5, 10,15 cm) after than plants complete establishment. Results indicated that the factor of change in plant density couldn’t affect the grain yield and the straw yield but the grain yield and the straw yield have significant difference at 1% and 5% statistical probability levels among the genotypes respectively. In this study the cream colour tepary bean with 2.1ton/ha and the black colour tepary bean with 1.37 ton/ha produced the highest and least grain yield respectively. The highest straw yield was related to cowpea genotype with 2.47 ton/ha and the least straw yield was related to black colour tepary bean with 1.71 ton/ha. also, the number of pod per plant, the number of grain per pod, the number of grain per plant were effected of planting density and were significant at 1%, 5% and 1% statistical probability level respectively. Different genotype of tropical bean from aspect traits of the number of pod per plant, the number of grain per pod, the number of grain per plant, the length of pod, the 1000 grain weight indicated significant effect at 1% probability level.
