The stages of harvest and post-harvest are of great importance in the rice crop. The objective of this work was to evaluate the effect of harvest time and storage period for the industrial, physiological seed quality and yield of irrigated upland rice. The study was carried out in 2002/03, in Selvíria county (state of Mato Grosso do Sul). The study was conducted in a randomized block design with seven treatments constituted by different harvest times (18, 20, 22, 24, 26, 28 and 30 DAF - days after flowering), with four replications. The harvested material was further stored for 12 months. Productive, physiologic and industrial characteristics were evaluated (0, 6 and 12 months). The BRS - Talent harvested about 28 DAF provided larger revenue of grains; better industrial quality was reached among 24 to 26 DAF; harvest period does not interfere in the physiologic quality; larger storage period (12 months) decreases the industrial and physiologic seed quality; however, the seeds fit to sowing.
