Morphological characterization and productivity of hybrid maize’s with ground and leaf nitrogen

Abstract

The maize crop fertilization is directly related to grain yield. There are alternative fertilizers to increase production, however unknown effect on the same. The aim of this study was to determine the effect of foliar fertilizers Quilt, Amminostim, Nutribond, Lixiviados and Control, with varying levels of N (100, 200 y 300 kg ha^-1) in hybrids P1684w, PUMA1167, H-40, H-51AE, H-57, M8092, FAISAN and SYN1806 in Valles Altos of Mexico State, on productivity and morphological characters, which used a randomized block design in plots divided, large plot to be managed as foliar fertilizer and a small plot of nitrogen levels, while blocking criterion was considered the hybrid. Analysis of variance was performed with the GLM procedure and comparison using the Tukey test with α = 0.05. Hybrid Faisan the best values record 5.5 t ha^-1 and 7.1 t ha^-1, respectively, surpassing grain yield 1.7 t to lower yielding hybrid PUMA 1167. The foliar fertilizer application did not increase the yield of straw and grain nor its morphological components, only an increase in plant height and cob with Nutribond fertilizer application. The use of a nitrogen level of 200 and 300 kg ha^-1 favored the grain and straw yields exceeding 1.1 t and 976.6 kg nitrogen level of 100 kg, respectively.
