Abstract
The climate phenomena of drought, aridity and desertification are increasingly present more often and continues to worsen as a result of the negative effects that technological progress intensively exerts on environment, especially on the climate. The present work aims to determine the influence of soil tillage, plant density and hybrid used on the diminishing effect of drought by maize crop with the intention of finding the best option to work. The associated influence of the soil tillage, plant density and hybrid used on the production of maize determined the highest yields by performing the combinator on the soil tillage, as basic tillage, using a density of 55,000 plants / ha and using hybrid PR36V52. Replacement the combinator tillage with plowing or direct seeding determined to obtain lower production up to 2000 kg/ha regardless of the hybrid used. In similar climatic conditions of agriculture in 2013, recording a poor distribution of rainfall, accompanied by a high temperature control throughout the growing season will mark the achievement of normal production the maize crop, between 5005 - 7950 kg/ha and the average production recorded a value of 6652 kg/ha.
