Productive response of the onion's crop (Allium cepa L.) to nitrogen fertilization and FitoMas-E®.

Abstract

In order to evaluating the productive response of the cultivation of the onion (Allium cepa L) with different dose of fertilization nitrogen and the application of FitoMas-E®, an experimental design of blocks was used at random, with four treatments and five repeated. The treatments consisted on the employment of FitoMas-E® and nitrogen dose at the 100, 75, 50 and 0% respectively. The following variables were evaluated: height of the plant, diameter of the base of the shaft, mass of the bulb and the yield. Starting from the obtained data it was carried out ANOVA and the Test of Duncan for 95%, with the statistical package STATGRAPHICS PLUS. It was found that the best crop response onion occurs under the effect of doses of 0 L.ha-1 of FitoMas-E®+N at 100% and 1,0 L.ha-1 of FitoMas-E®+N 75% respectively, the latter being the better off the report 7.58 t ha-1 and $139,859.81 profit.
