Effect of inoculation with mycorrhizal fungi on the production of native corn (Zea mays L.) in Valle de Santiago, Gto

Abstract

The experiment was established from june-december 2022 in a randomised block design with three replications in experimental plot 1 of the Sustainable and Protected Agriculture Career of the Universidad Tecnológica del Suroeste de Guanajuato (UTSOE), located in the municipality of Valle de Santiago. The objective was to evaluate two varieties of native corn of the race harinoso de ocho (red and white) with inoculation with two commercial products containing mycorrhizal fungi (Rhizovibac® and Tec-myc®), a chemical fertilisation based on INIFAP (2015), of 80-40-00 and a fertilisation with vermicompost at a dose of approximately 100 g/mata. The experimental unit consisted of three furrows of eight metres long and 75 cm apart, where root volume - weight and yield were evaluated. Significant differences were found in Fisher's LSD (p≤0.05) for the variables of root volume and weight in the white maize 128.3 cm3 above the mean 72.1 cm3 with chemical fertilisation; however, the criollo corn was the one that obtained the best yield. It can be identified that there is a high relationship between root volume and root weight. In the case of the treatments of the commercial products used in the white corn with Tecmyc®, the lowest root volume - weight and the lowest yield was obtained with the use of Rhizovibac® in comparison with the red corn.
