Global Maize Project in Mexico: Celaya, Guanajuato

This experiment is part of the Global Maize Project that aims at identifying sustainably intensive technological options for maize.

Vegetative growth and the potential to accumulate yield, consequently the need to supply nutrients, vary with the conditions of the different locations where corn is cultivated. This is particularly true in the corn producing areas of tropical Latin America where the diverse climate conditions result in different yield potentials. In tropical areas, latitude and altitude have a profound effect in yield accumulation. Read more

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.

The study started in 2009 in Celaya, State of Guanajuato, at 1,830 meters above sea level, in an environment classified as non-equatorial, tropical–subtropical, mid-altitude.

The study was started in 2009 in Celaya, State of Guanajuato, Mexico, at 1,830 meters above sea level. The treatment design included a combination of two management systems (plant populations) (Farmers’ practice [FP] and a higher population [EI]) and three N fertilization regimes (0-N, 300 kg N/ha applied two out of three years, and 300 kg N/ha applied every year).

The central region of México known as “Bajío” has been historically very important due to its environmental conditions that favor high agricultural productivity. The dominant Vertisols present management challenges related to their limited internal drainage that reflects in the efficiency of utilization of N and appropriate soil aeration conditions for the crop. Planting two rows on top of 0. 8 m beds has been growing as a standard practice among maize farmers in the area.

The corn producing areas of tropical Latin America provide a diverse set of climatic conditions that result in a wide range of yield potentials, and consequently, nutrient requirements. In tropical areas, latitude and altitude have a profound effect on yield. For these reasons, it is necessary to determine yield potential and attainable yield under the best known management practices. It is also necessary to quantify the effect of such management on nutrient use efficiency, particularly N.
