Abstract
The productivity of upland rice increases with the number of plants per unit area to the point where intraspecific competition for nutrients, water, light and other factors of production limits the productive process. The objective of this work was to evaluate the effect of spacing on the production of highland rice irrigated in the brazilian savannas. The experiment was conducted from May to October of the year 2015 in Goianésia -GO, in the experimental area of the Evangelical Faculty of Goianésia. The BRS Primavera variety was tested in four spacings (20, 30, 40 and 50 cm) between rows and density of 100 seeds per meter and used as sprinkler irrigation. The experimental design was in randomized blocks, with four treatments with three replicates. The results showed that the spacing of 30 cm between rows provided higher productivity in the BRS Primavera variety.
