To evaluate The planting pattern effects on phonological characteristics yield and yield components of tropical beans genotypes experiment was conducted in Jiroft Islamic Azad University research farm during 2009. The experiment used in split plot design based on RCBD with four replications. Plant arrangements were considered in three levels as one row on the stack with a distance between a plant 10 cm، two rows on the stack with a distance between plants 20cm and three rows on the stack with a distance between plants 30cm، as the main plot and genotypes at three levels (cowpea، cream tepary bean and black tepary bean) as sub plot were studied. Characteristics such as grain yield، straw yield، the number of pods per plant، seeds per pod، and average pod length، plant height، seed weight، and harvest index، number of seeds per plant، biological yield، and changes in dry weight were studied. The trait of black tepary bean with planting arrangement of three rows on the stack with a distance between plants 30cm with the maximum number of pods per plant (20. 90) and maximum number of seeds per plant (266. 5) and maximum harvest index (46. 55%) to black tepary bean with planting arrangement of two rows on the stack with a distance between plants 20cm. Genotypes that studied of the number of pods per plant، seeds per pod، average pod length، seed weight and، number of seeds per plant in the 1% probability level were significant.

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.
