- Abstract
The aim of this study is to evaluate the effects of the forms of molybdenum application associated with the nitrogen topdressing on the yield components and grain yield of wheat. The experiment was conducted with a randomized block design with split plots and four repetitions. In the plots were assessed four ways to molybdenum application: Control (no molybdenum); Seed treatment (40 g ha-1 molybdenum); Foliar treatment (40 g ha-1 molybdenum); and Seed treatment (20 g ha-1 molybdenum); + Foliar treatment (20 g ha-1 molybdenum). The subplots were applied four doses of nitrogen (0, 30, 60 and 90 kg ha-1). It was evaluated: plant height, number of spikes m-2, number of spikelets per spike, number of grains per spikelet, number of grains per spike, thousand grain mass, hectoliter weight and grain yield. The data was submitted to analysis of variance and regression analysis to 2nd degree, at 5% probability. The aplication of molybdenum don't results in improves in the yield performace of the wheat crop. The increase in nitrogen rates in coverage decreases the thousand grain mass, but increases plant height and grain yield.
