| Sumario: | The objective of the study was to determine the dry matter production, grain yield, its components and profitability in three corn genotypes in response to nitrogen and biofertilizer, in a cold climate. The study was established in Montecillo, State of Mexico. The treatments consisted of the planting of Michoacan-21 native corn, a synthetic variety HS-2 and Promesa hybrid, which were inoculated with biofertilizers, in different levels of nitrogen 0, 80 and 160 kg ha-1. At physiological maturity, the total dry matter (DM), grain yield (GY) and its components were evaluated. Additionally, an economic analysis was carried out. The application of biofertilizer and nitrogen caused increases in the production of DM and GY and their components depending on the genotype used. Michoacan-21 presented a positive effect with the use of biofertilizer in DM and GY. In general, the highest DM was achieved with the application of 160 kg ha-1 of nitrogen in the HS-2 genotype and in the case of GY the highest was with Promesa and 160 kg ha-1 of nitrogen, which presented the highest net and total income. |
