Arranjo espacial e adubação para formação de jardim clonal de gliricidia à produção de tutor vivo para o cultivo da pimenta-do-reino

Abstract

The use of live stalks for black pepper cultivation is an alternative that contributes to sustainable production. However, the availability of live gliricidia cuttings as a live tutor for black pepper in the State of Pará is low due to the lack of technical information on the cuttings production system of this species for this purpose. In order to establish agricultural practices aimed at producing live gliricidia tutors for black pepper cultivation, the effects of (i) spacing arrangement and (ii) nutritional supplementation were evaluated, regarding the diameter of the gliricidia mother plant; number and diameter of branches for live cuttings over a 24-month period. Significant differences between spatial arrangements and fertilizer levels (N, P, K) were observed only in the first evaluations. At the end of the cycle there was equivalence in the individual production of live cuttings for tutors, both in relation to spatial arrangements and nutritional supplements. However, 2.0m x 1.5m spacing and foundation fertilization are suggested as recommended practices for the formation of a clonal garden aiming at the production of live cuttings due to the greater number of cuttings obtained at the end of the cultivation cycle.
