Influence of Raphanus raphanistrum L. Density and Relative Time of Emergence on Bean Crop

Abstract

The objective of this study was to evaluate the influence of emergence times and density of R. raphanistrum plants on bean cv. ‘Rubi’ development and pods production. The experimental design utilized was factorial (2 x 5) in randomized blocks with three replications. There were two relative times of emergence of wild radish in relation to bean (at the same day of bean and when the bean had the first trefoil fully expanded) and four R. raphanistrum densities (1, 2, 4 and 8 plants per pot, or 3.33, 6.66, 13.32 and 26.64 plants m-2 and a control with only one bean plant). There was no difference between the relative times of weed emergence on the bean development. The presence of R. raphanistrum from 2 plants per pot provided negative effect on the beans features dry weight of leaves, leaf area, and dry weight of pods.
