Abstract

Nitrogen is the nutrient most absorbed by common bean plant, and molybdenum besides its importance to N fixation process, is associated to N metabolism. Thus, this micronutrient lack produces symptoms like those caused by N deficiency. This research had the objective of evaluating, on common bean crop, the effect of N doses application in side dressing (0, 30, 60 and 90kg ha^-1) as well as its interaction with leaf application of Mo (0 and 80g ha^-1) in development phases V3 and V4 under no tillage system. The experimental design was the one of randomized blocks with 16 treatments and 4 repetitions. The research was carried out in Selvíria-MS on soil previously cropped with corn. The application of leaf trough Mo, in both analyzed phases, doesn’t interfere on the productivity. The application of increasing doses of nitrogen in side dressing has caused a crescent increase in nitrogen level on leaves, but it didn’t interfere on grains productivity.
