Abstract

The objective of this work was to evaluate the productive performance of different maize hybrids in different municipalities and microregions of the State of Rio Grande do Sul. The experimental design was in strips using 15 corn hybrids, sown in different regions of the State of Rio Grande do Sul. Grande do Sul in the 2019/2020 crop season. The productivity data obtained in each location were tabulated and later submitted to a descriptive statistical analysis, with a variable characterized as discrete quantitative. In the municipality of São Lourenço do Sul, maize hybrids with accumulated growing degree days of 800, 803, 804, and 840 exhibited the highest grain yield performance. For the municipality of Santa Cruz do Sul, the hybrid that had the best performance was 848 degrees day. Anta Gorda and Caçapava de Sul obtained the same results, with the hybrids 782 and 803 degrees days with the best productivity performance. In Picada coffee, the hybrids with degrees day of 793, 831 and 848 had the highest productivity compared to the other hybrids. The hybrids with degree days of 782, 803, 793, 831 and 848 showed the highest average yields, regardless of the municipality where the experimental tests were carried out.
