AVALIAÇÃO AGRONÔMICA DE CULTIVARES DE TRIGO SOB CULTIVO IRRIGADO NO CERRADO DE HIDROLÂNDIA-GO

Abstract

Wheat (Triticum aestivum L.) is one of the world's main agricultural crops, playing a fundamental role in human food supply and the agricultural economy. In Brazil, although production is concentrated in the Southern region, the development of cultivars adapted to the Cerrado has enabled the expansion of the crop to new producing areas, including the state of Goiás. In this context, the present work aimed to evaluate the agronomic performance of seven wheat cultivars grown under the edaphoclimatic conditions of the Goiás Cerrado. The experiment was conducted in the municipality of Hidrolândia-GO, in a randomized block design with four replications. The variables evaluated were dry matter, plant height, grain weight in the ear, grain weight without husk, and distance between nodes. The data were subjected to analysis of variance (ANOVA) and, when significant, the means were compared using Tukey's test at 5% probability. The results showed a significant difference only for the dry matter variable, in which the Duque cultivar presented the greatest biomass accumulation. For the other variables, no statistical differences were observed between the cultivars, although numerical differences did occur between the evaluated materials. The Duque and TBIO cultivars generally presented the highest average values ​​for characteristics related to vegetative development and production components, indicating good potential for adaptation to Cerrado conditions. The results highlight the importance of regional cultivar evaluation as a tool to support technical recommendations and contribute to the sustainable expansion of wheat cultivation in the Brazilian Midwest.
