Avaliação agronômica de híbridos de canola cultivados no Cerrado de Minas Gerais

Abstract

The cultivation of canola (Brassica napus L.) in the Cerrado biome of Minas Gerais has garnered increasing interest, presenting a viable option for diversifying agricultural production in the region. Research has yielded promising results, highlighting canola's positive performance in the Minas Gerais Cerrado. Consequently, a study was conducted to evaluate the growth and development of canola hybrids cultivated in this region. The experiment was carried out at the Fazenda Experimental do Glória (18°56'52"S and 48°12'52"W, at 921 m altitude), part of the Federal University of Uberlândia. Hybrids Diamond, Hyola 433, Hyola 575CL, Hyola Blazer, Alht B4, and Nuola 300 were sown on March 18, 2023. Harvesting occurred between June 7 and July 25, 2023, adjusted according to the maturation of each hybrid. During the experiment, the following parameters were assessed: number of days from emergence to end of flowering, number of days to 50% flowering, duration of flowering (days), plant height (cm), silique length (cm), and number of grains per silique. Under the cultivation conditions of this trial, hybrids exhibited differences in plant growth and development characteristics. Analysis of sub-periods revealed a tendency for hybrids to increase the number of days required to complete their cycle. Siliques produced by the Diamond and Alht B4 hybrids were longer and contained a higher number of grains. Average plant heights exceeded the overall mean, remaining within the range indicated by the developers for all hybrids, with values varying from 140 to 162 cm.
