Análise das características agronômicas de trigo forrageiro (Triticum Aestivum l.) Cultivar MGS brilhante semeado em diferentes

Abstract

Dual-purpose wheat (Triticum aestivum L.) exhibits high potential for integration into production systems, particularly in regions with climatic constraints during the off-season, such as the state of Minas Gerais. In this context, sowing date is a key factor influencing crop growth, development, and biomass accumulation. This study aimed to evaluate the agronomic characteristics of the cultivar MGS3 Brilhante under different sowing dates. The experiment was conducted at the Federal Institute of Education, Science and Technology of Minas Gerais – Bambuí Campus, using a randomized complete block design, with four treatments (July 11, 18, and 25, and August 1, 2024) and five replications. Morphophysiological and productive variables were evaluated, including plant height, number of leaves, tillers, and spikes, spike length, as well as fresh and dry mass production. Data were subjected to analysis of variance (ANOVA), and means were compared using Tukey’s test at the 5% probability level. A significant effect of sowing dates was observed on variables related to biomass production and yield components, with superior performance in earlier sowings. Conversely, late sowing reduced the agronomic performance of the crop. The variables number of leaves and spike length showed no significant differences among treatments. It is concluded that early sowing is an efficient strategy to maximize biomass production of forage wheat under the edaphoclimatic conditions of Bambuí-MG.
