Abstract
Forage corn is a crop in greatest demand in the Comarca Lagunera. The objective is to obtain the models for the production indicators of forage maize hybrids, which could improve the production systems. The variables evaluated were: leaf area index (IAF), number of leaves and dry matter (DM). The DM model as a function of the IAF was 17.13 grams plant per unit of IAF. For the days after sowing (DDS) a production of 5 grams plant / elapsed day was found. For IAF based on DDS, 0.36 units of IAF were obtained per day and the IAF increased by 0.65 units as a function of the number of leaves. It is concluded that the behavior of the evaluated variables provides results of linear and polynomial regression models, with different levels of reliability, which allow future estimates to be made to choose the hybrids that best adapt to the region.
