Abstract
Field experiments with 11 native maize hybrids for grain production FAO maturity group 400-600 were set up over two years at two sites (near the villages of Brzan and Lužnice, Kragujevac municipality) with the aim of, based on the yield over years, recommending hybrids for specific agroecological conditions. The average maize grain yield for all hybrids in 2017 was 4.2 t ha-1, and in 2018 11.1 t ha-1. Hybrids ZP 548 and NS 5051 had the highest average grain yield in 2017, and in 2018 ZP 560 and NS 4051. Higher yields in 2018 are mainly the result of a larger amount and a more favorable distribution of precipitation in the vegetation period. In both years, which differed in agrometeorological conditions during the vegetation period, especially in the amount and distribution of precipitation in the second part of the vegetation, in which the critical phases of maize development take place, the highest yields were recorded mainly in FAO 500 hybrids.
