Yielding performance of wheat cultivars subjected to different management techniques | Yielding performance of wheat cultivars subjected to different management techniques

Английский. Wheat (Triticum aestivum L.) is one of the most cultivated and consumed crops worldwide, playing a crucial role in food security and global trade. In Brazil, more than 85% of national wheat production is concentrated in the southern region, where the choice of cultivar and management practices directly affect crop performance. This study aimed to evaluate the productive performance of 14 wheat cultivars subjected to two different management techniques: chemical and chemical + biological. The experiment was conducted at the Experimental Farm of the Universidade Regional do Noroeste do Estado do Rio Grande do Sul (Unijuí), in 2024, using an incomplete factorial block design. Agronomic traits, pest and disease incidence, and the interaction between treatments and genotypes were assessed. The results indicated that chemical management resulted in greater plant height, number of leaves, ear length, and number of grains per ear, while chemical + biological management promoted a higher number of spikelets per ear. The cultivars TBIO PONTEIRO and ORS SOBERANO excelled in spikelet formation, while TBIO CAPAZ, TBIO TRUNFO, and TBIO TALISMÃ showed a higher number of grains per ear. These findings highlight the importance of cultivar selection and integrated management strategies to optimize wheat yield under different environmental conditions.
