Crescimento do milho BRS catingueiro irrigado no cariri cearense

Abstract

Corn is grown throughout Brazil, has great economic importance due to various forms of use, from food and feed to the high-tech industry and use in biofuel production, and productivity of corn in Northeast It is low due to the predominance of production systems that use little or no technology and have insufficient rainfall and irregularity. Based on the foregoing, the aim of this study was to evaluate the effects of different irrigation levels calculated by evaporation percentage of tank class “A” (20, 30, 40, 60, 80, 100, 120 and 140% ECA) the growth of the corn BRS catingueiro in Ceará cariri region. The growth variable, stem height, was influenced by irrigation levels used, with higher value with a blade referring to 80% of the ECA and the variables stem diameter and dry mass of shoots (stems and leaves) were not affected by blades Irrigation used.
