Comparison of different growth analyse indices for Vigna and Tepary Jiroft, Iran local beans germplasms in various plant densities

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.
