Nitrogen Fertilization Combined with Biostimulant in Second-Crop Maize
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 6, Issue 5
Abstract
In the aspects of production system for the corn crop the use of Biostimulant have great prominence. Thus, the objective of this study was to study the behavior of corn crop in the second crop in response to nitrogen doses and Biostimulants. The study was conducted at the Experimental Farm Luiz Eduardo de Oliveira Sales, in the municipality of Mineiros-GO. A randomized block design using a 5x2 factorial, corresponding to five doses of nitrogen fertilization based on urea (0, 60, 120, 180 and 240 kg ha-1) was applied in two situations (presence and absence) of Festize Biostimulant Peixe® in three replicates. The planting took place on February 24. The system adopted was no-tillage with cv. 310 PRO2 in a population of 54,000 ha-1 plants. Nitrogen fertilization was applied in the phenological phases V4 and V8, with 50% for each and the Biostimulant in a single dose between the V7 and V8 stages, using a concentration of 2% of the commercial product and syrup in the volume of 400 l ha-1. At the end of the experiment on July 13, 2016, the variables were taken. The results were submitted to analysis of variance, polynomial regression and comparison of means by Tukey test at 5% of probability. The use of Biostimulant did not influence the morphological characteristics evaluated as stem diameter, plant height, ear insertion height, ear diameter, ear length and productivity. According to the experimental conditions it is recommended the cultivation of corn cv. 310 PRO2 in the presence of Fert Peixe® Biostimulant combined with 145 kg of nitrogen.
