- Abstract
The experiment was carried out in 2008/2009 under field conditions in the Campus Cedeteg of UNICENTRO in Guarapuava, Paraná, to evaluating the effect of grazing by lamb and nitrogen fertilization in winter and summer season on bean crop. The experimental design was in randomized blocks with sub subplots with three replications. The main plot was composed of nitrogen doses (0, 75, 150 and 225 kg ha-1) in black oat and ryegrass pasture during winter season; the subplots were composed of grazing by lambs; and the sub subplots were nitrogen doses (0, 60, 120, 180 and 240 kg ha-1) in summer season in the bean crop. The grazing did not show effect on bean yield. The winter nitrogen fertilization singly did not affect the yield components, whereas the plant height, number of branches, number of pods and thousand grains mass had quadratic response due to summer nitrogen fertilization. There was interaction between nitrogen fertilization in winter and summer on number of nodes per plant and bean yield. Therefore, residual effect of nitrogen applied on pasture was verified on bean crop, which indicates this strategy could be adopted by farmers as a way of maximizing the forage and animal production in winter season and it would also benefit the bean crop in succession.
