Abstract
This study aimed to assess the performance of commercial corn hybrids with the application of Trichoderma harzianum under varying nitrogen levels. The experiment was conducted at the State University of Goiás, Campus Sul, during the 2022/23 harvest. The experimental design employed a factorial scheme 9 x 3, involving nine commercial hybrids and three nitrogen doses, randomized in blocks with three replications. Three nitrogen doses were applied- control (160 kg ha-1 of nitrogen), low nitrogen (80 kg ha-1 of nitrogen), and low nitrogen (80 kg ha-1 + Trichoderma harzianum). The evaluation encompassed ear height, plant height, relative chlorophyll index, stem diameter, number of rows, number of lines, and dry grain mass. The hybrids 2M77, 2M80, P3898, and P4285 exhibited superior efficiency with 80 kg ha-1 of nitrogen, while DKB390 and P3898 demonstrated the highest responsiveness to the recommended dose of 160 kg ha-1 of nitrogen. The inoculation of Trichoderma harzianum, combined with 80 kg ha-1 of nitrogen, resulted in increased grain mass, in the hybrids 30A91PW, DKB390, GNZ7280, P4285, and RK3014, with variable benefits across different characteristics. However, it is advisable to limit the use of Trichoderma harzianum to these specific commercial cultivars.
