Absorção de boro e crescimento do maracujazeiro adubado com boro e material de cupinzeiro

Abstract

The aim of this study was to evaluate the effects of boron doses and nest of termites material on growth components, concentration and accumulation of boron in shoots of yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg.), grown in Red Distrophic Latosol. The experimental delineation was randomized completely, in factorial design 5 x 4, with five doses of boron (0; 0,25; 0,50; 0,75 e 1,00 mg dm-3), and four doses of the material termites mound nest (0; 25; 50 e 75 g dm-3), with four replications. The experimental unit was composed of vessels with up to 700 cm3 samples. The experiment was conducted in green house at the Faculty of Agricultural Sciences of UFGD, in Dourados-MS. The higher values of production on dry matter of shoots, plant height, leaf area, stem diameter and chlorophyll content are obtained by joint application of nest of termites material in maximum dose and between the two higher doses of B. The nest of termites material was low effective as boron source to promote changes on growth components of passion fruit plant, evaluates.
