Efeito de doses de N-P-K sobre as características agronômicas do abacaxizeiro

Abstract

Fertilization is a major factor in the management of any crop, in pineapple culture it is responsible for providing higher quality fruits. In view of this, the objective of this work was to evaluate the effect of different doses of N-P-K on the quality of the pineapple fruit. The experiment was carried out in DBC and tested 5 treatments with increasing doses of NPK (0, 18, 36, 54 and 72 g / plant), the variables analyzed were: fruit mass, fruit circumference, fruit length, crown mass, crown length, and SST. The values ​​obtained were subjected to analysis of variance and regression test. The increase in fertilizer doses in the pineapple culture promoted greater fruit development, where maximum fruit mass productivity was obtained with application of 72g of the fertilizer formulated per plant.
