Conteúdo: | Abstract: We evaluate the feasibility of using foliar-applied molybdenum, (Mo) instead of side-dressed nitrogen (N) in three experiments. In soils with native rhizobia, plants received 0, 30, 60, 90 or 120 kg N ha-1 with +Mo (80 g ha-1) or -Mo. N concentration in leaves (NCL) -Mo ranged from 35.1 to 42.5 g kg¡1 and NCL CMo from 40.3 to 49.2 g kg-1; yield -Mo ranged from 1560 to 3350 kg ha-1 and yield +Mo from 2829 to 3567 kg ha-1. In two experiments, NCL or yield -Mo increased linearly or quadratically with increasing N rates, but NCL or yield -Mo did not. In one experiment, NCL increased linearly with increasing N rates and 16% with +Mo relative to ?Mo, but yield was not affected significantly. Our results suggest that using Mo fertilizer instead of side-dressed N can allow common bean plants to meet crop demands for N to support yields as high as 3000 kg ha-1.
