Efecto de la fertilización nitrogenada sobre las poblaciones de hongos micorrízicos de suelos y en la producción de maíz (Zea mays L.), en la zona de Babahoyo

This research work was carried out in the experimental farm of the Faculty of Agricultural Sciences at the University of Babahoyo located at km 7.5 of the Babahoyo Montalvo road, in the province of Los Ríos, the UTM coordinates are -1.800659 E and -79.482175 N. The area has a tropical climate according to Köppen classification, with an annual temperature of 24.2 ° C, precipitation of 1934.1 mm / year. As a planting material, the Somma corn hybrid was used. The treatments were made up of twelve treatments with 3 repetitions that gives a total of 36 plots. The first six treatments were applied with Vam mycorrhizae from Huxtable at doses of 1 l / ha with different levels of nitrogen fertilization ranging from 180, 160, 140, 120, 100 and 0 kg of nitrogen, the remaining six treatments that were without mycorrhiza applications, they also had the same fertilization levels of 180, 160, 140, 120, 100 and 0kg. The statistical design that I use for this investigation was factorial, for the calculation of the analysis of variance was that of tukey at 95%. For the establishment of the crop, the relevant cultural work was carried out, such as soil preparation, weed control, irrigation, fertilization, control of insect pests and diseases, harvest. For the results obtained, it was determined that the best treatment in terms of economic benefit and best performance that the economic analysis showed was the treatment with mycorrhizae applications and 180kg of nitrogen fertilizer with a production of 7867.70 kg / ha, that is 174, 83 qq, with a net benefit greater than the other treatments with $ 793.48,
