CRESCIMENTO DE Solanum lycocarpum St.-Hil. EM FUNÇÃO DA ADUBAÇÃO MINERAL E ORGÂNICA EM REJEITO DA MINERAÇÃO DE QUARTZITO 1

Abstract

In order to evaluate the behavior of Solanum lycocarpum, grown in sterile tailings, from mining of quartzite under the influence of mineral and organic fertilization to support actions for the recovery of exploration areas of quartzite, it was conducted an experiment in a greenhouse in a completely randomized design with four replications The treatments consisted of five combinations of mineral (MF) and organic (OF) fertilizer and an additional treatment of the sterile reject without MF and OF (Witness). The combinations were: 0%OF/100%MF; 25%OF/75%MF; 50%OF/50%MF; 75%OF/25%MF; 100%OF/0% MF. Doses of 100% MF and OF were de 150 mg de N, 140 mg de P, 150 mg de K, e 5 g bovine manure per dm3 of sterile. The Solanum lycocarpum responded to mineral fertilization with the recommended doses of 36 mg N, 33,6 mg P e 36 mg K e 3,8 g bovine manure per dm3 of sterile tailings from mining of quartzite. The accumulation of nutrients in the species Solanum lycocarpum at recommended doses in the following order was on the shoot: N> K > Ca > P > S > Mg >Mn> B > Fe > Cu > Zn with fertilization mineral and organic for maximum growth of the of species.
