2013 Annual Interpretive Summary


This project is being conducted near Celaya, in the state of Guanajuato, Mexico, at 1,830 meters above sea level. This environment is classified as mid-altitude, non-equatorial and tropical–subtropical. In 2013, the treatment design was modified to include two tillage systems: Conventional tillage typical of farmers current practices and conservation tillage, which involves direct seeding without tillage. These tillage treatments were combined with three N fertilization regimes: 0 N, 300 kg N/ha following 0 N in 2012, and 300 kg N/ha applied every year. No significant differences (p > 0.05) in grain yield were detected between the tillage treatments when no N was applied or when fertilized with 300 kg N/ha.
