Abstract

This research evaluated the variation of depth irrigation in the maize culture growth (Zea mays L.) for obtaining the baby corn, determined from the culture evapotranspiration, based on class A pan evaporation and applied when the evapotranspiration reached follow the accumulated values: T1 - 15 mm, T2 - 30 mm, T3 - 45 mm and T4 - 60 mm. The statistical design was the outlinement completely whit four treatments and whit five repetitions, the results had been submitted to the statistics analysis for the Sisvar program and determined it variance analysis and the treatments averages had been compared in 5% of probability for the Tukey test and the regression analysis. Five plants were selected for analysing the growth for parcel. The characteristics that belongs to the growth: plant height (PE), leaf number (LN), foliar area (FA) and foliar area index (FAI). Were observed significant differences in the values of FA and FAI. The increase in the depth irrigation and the application frequency implied in bigger values of FA and FAI
