Effect of weeds competition on some growth parameters of red, white and pinto bean (Phaseolus vulgaris L.)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 5
Abstract
In order to investigate the effect of weeds competition on growth parameters of different dry beans, an experiment was conducted at Research Station of Faculty of Agriculture at Tabriz University, Tabriz, Iran in 2011. The experiment was conducted as split plot based on randomized completely block design with three replications. The main plots were three types of dry bean including red bean, white bean and pinto bean and the two sub plots were weed free and weed infested treatments. The results indicated that interaction effect of weed treatment × dry bean type on plant height was significant. Weed infested treatment had not significant effect on red bean plant height but reduced the plant height of white and pinto bean. The effect of dry bean type and weed treatment was significant on leaf area index (LAI). The LAI of weed infested treatment was significantly lower than that of weed free. Also the LAI of red and white bean was significantly higher than that of pinto bean. The effect of dry bean type was not significant on dry bean total dry matter (TDM) and crop growth rate (CGR). Weed infested treatment reduced TDM and CGR of dry bean significantly. Among the growth parameters, the LAI was the best index for competitiveness of dry bean against weeds.
