Descrição do desempenho produtivo dos híbridos AG 8780, GNZ 7740 e GNZ 7788 nas condições edafoclímicas de Nossa Senhora da Glória

Abstract

Corn is a crop of global economic importance and widely cultivated in the semiarid region of Sergipe, one of the purposes for which is animal feed. Semiarid regions suffer from long periods of drought and poor rainfall distribution that often do not meet the crop's needs. However, in order to alleviate these problems, the development of genotypes suitable for this region has been observed. Thus, this study aimed to describe the productive performance of the corn genotypes GNZ 7740, AG 8780 and GNZ 7788 under the soil and climate conditions of Nossa Senhora da Glória-SE. The genotypes were cultivated, in the agricultural years of 2022, 2023 and 2024, at the Embrapa Experimental Farm - Semiárido, located in Nossa Senhora da Glória/SE. In the cultivation, a spacing of 0.7 meters was used, in dryland. The evaluations made were ear weight, total grain weight in the plot, plant height, ear height, relative position of the ear, male flowering (days), female flowering (days) and productivity. In field cultivation, the genotype GNZ 7740 presented its best productivity in the year 2023, with 6,940.66 kg/ha, AG 8780 obtained its highest productivity in the year 2023, with 7,819.35 kg/ha and GNZ 7788 achieved a productivity of 3,011.59 kg/ha, in the year 2022. Finally, it is concluded that the genotypes presented productive potential that fell within the national and state productivity average, with only the genotype 7788 GNZ VIP 3 being below the average.
