TRIGO E TRITICALE IRRIGADO EM TERCEIRA SAFRA NA REGIÃO DO CERRADO

Abstract

Wheat and triticale are important winter cereals in Brazilian agriculture, but domestic production still does not meet domestic demand, reinforcing the need for imports and encouraging the expansion of cultivation into new regions. In the Cerrado, sowing is concentrated in the dry season due to more favorable temperatures. However, the scarcity of rainfall requires the use of irrigation. In this context, given the challenges of adapting wheat cultivars in the Brazilian Cerrado region in the third harvest, the objective was to evaluate the productivity traits of wheat and triticale genotypes subjected to three irrigation depths (30, 60, and 90°C of Crop Evapotranspiration (ETc). This study was conducted at the Federal University of Mato Grosso do Sul's Campo Escola Farm, located on the Chapadão do Sul, Mato Grosso do Sul, campus in 2023. Seven wheat cultivars (BRS Atobá, BRS Coleiro, BRS Gralha Azul, BRS Jacana, BRS Sabiá, IPR Catuara TM, and IPR Potyporã) and two triticale cultivars (IPR Aimoré and IPR Caiapó) were analyzed, subjected to different irrigation depths. The following evaluations were performed: plant height; number of grains per plant; number of panicles; 100-grain weight; and yield. The results show that, among the irrigation depths, the one with the best results was the one with 90% ETc. The wheat cultivar BRS Gralha Azul excelled in all variables evaluated, while for triticale, the cultivar IPR Aimoré achieved the best results for all variables evaluated.
