CRESCIMENTO DE MUDAS DE JAQUEIRA (Artocarpus heterophyllus) EM FUNÇÃO DE VOLUMES DE ÁGUA E HIDROGEL

Abstract

The objective of this work was to evaluate the effect of water management, using different water slides correlated to the use of hydro absorbent polymer as soil water retention in post - planting seedlings of Artocarpus heterophyllus. The experiment was conducted in greenhouse Department of Plant Science and Environmental Sciences of the Center of Agricultural Sciences (CCA) of the Federal University of Paraíba (UFPB). Using a completely randomized experimental design in a 4X2 factorial scheme with blades 0,5 ;1; 1,5; 2 (gl 1-1), with and without hydrogel application. Irrigation frequencies consisted of starting from day 1 on a subsequent day 15, day 30 day 45 day 60 and day 75. The experiment was composed of four treatments, each treatment with a plot composed of 25 plants, totaling 100 plants added to the Treatments. Plant height, stem diameter and number of leaves and monitoring of plant survival were evaluated biweekly. Data were submitted to analysis of variance and regression.
