This work aimed to evaluate the sowing time of popcorn hybrids and its impact on yield and grain yield components. The study was conducted in the experimental area of the Federal University of Santa Maria, Campus of Frederico Westphalen, during the 2019/2020 agricultural year. The experimental design was of randomized blocks, in a two-factor scheme, with four sowing times (08.21, 09, 30, 09 and October 19, 2019) and six popcorn with hybrids (H1, H2, H3, H4, H5 and H6), with four repetitions. There was an interaction between the factors for the components: ear length, ear diameter, cob diameter, plant height, ear insertion height, number of rows per ear, number of grains per row, number of grains per row, number of grains per ear and mass of a thousand grains. In the comparison between hybrids, all evaluated stability on grain yield, with an average of 7.235 kg ha-1. The popcorn hybrids used must be only until 09.11.2019 in southern Brazil, as they produce 60% more, compared to late sowing, for the conditions in which the experiment was carried out.
