Abstract:
e of this study was to evaluate the agronomic performance of corn cultivars for grain production in the south at low altitude in the Cerrado-Amazon ecotone. Place: The research was carried out at Sítio Vitória (8°18'32.0"S, 50°36'58.0"W, 278 MASL), in the south of the state of Pará, Brazil. Study Design: The experimental design was randomized blocks with twelve treatments and three replications. The treatments were eight corn hybrids: AG 1051, AG 8088, BM 3051, BR 2022, BR 205, BR 206, BRS 3046 and PR 27D28; and four open pollination populations: AL BANDEIRANTE, ANHEMBI, CATIVERDE and M 274. Methodology: Sowed on January 28, 2019. The following characteristics were evaluated: ear height, plant height, number of grains per row, ear diameter, ear length, ear weight and grain yield. Results: The cultivars showed a difference for all traits. The grain yield of the cultivars ranged from 4,567 kg ha-1 (BR 205) to 9,450 kg ha-1 (AG 1051). Conclusion: The hybrids AG 1051 and BM 3051 were the ones that stood out the most, had the best performance in the Cerrado-Amazon ecotone.
