Abstract

Rice is the main food crops in the world, being the basic constituent of the Brazilian population's food, which is of great importance in the country's economy. For a increase the productive potential and economic performance, effective and continuous research support is critical for the generation of new technologies. The present study has the objective of evaluating the rice yield, BRS - Esmeralda cultivar and micronutrient fertilization via soil and leafs, in two physiological stages (flowering and grain filling). The experiment will be conducted in a greenhouse, from the College of Agricultural and Technological Sciences, UNESP, Campus de Dracena, SP. The experimental design will be in a randomized block with 5 replicates. The treatments will be arranged in a 2x3 factorial scheme, the first factor being the presence or absence of micronutrients in the soil fertilization and the second factor the leafs application (without leafs application, application in flowering and application in grain filling), totaling six treatments. The effect of the treatments will be measured by the dry matter production of shoot, number of tillers, dry mass of roots, number of panicles, total number and fertility of spikelet, weight of 100 grains and total grain, concentration of N, P, K, Ca, Mg, S, Cu, Fe, Mn and Zn in the leaf diagnostic. The data will be tested for error normality and homogeneity of variance. The results will be submitted to the ANOVA, verified significant, will be realized the comparison by the Tukey test at 5% probability.
