ADUBAÇÃO ORGÂNICA E CINZA DE MADEIRA NO DESENVOLVIMENTO VEGETATIVO DO JILOEIRO(SolanumaethiopicumL.)

Abstract

Jiloeiro is a vegetable widely cultivated and consumed in Brazil. The balanced fertilization of the plant with organic and mineral source ensures good nutrition. The objective was to evaluate fertilization with bovine manure enriched with vegetable ash in different concentrations in the vegetative development of the jiloeiro culture. The experiment was carried out in a greenhouse at the IF Goiano - Campus Morrinhos. A completely randomized design, seven treatments and four replications were used. The seedlings were acquired in a suitable nursery and transplanted 40 days after sowing. In preparing the substrates for transplanting, a homogeneous mixture of soil and sand in a 2: 1 (v / v) ratio was performed to fill vessels with a capacity of 4.0 L. After the seedlings were transplanted, fertilization was carried out at planting with the following compounds: bovine manure, vegetable ash and NPK. The cover fertilization was performed only for the treatment with mineral, divided into six plots every 15 days after transplantation (DAT). After 104 days after transplantation, plant height, stem diameter, chlorophyll content and leaf number were evaluated. There was a significant difference (P≤0.05), for the variables in which the mineral fertilizer was used, providing greater height, diameter, number of leaves and SPAD index. Manure fertilization enriched with vegetable ash did not influence the vegetative development of the jiloeiro. The doses of bovine manure enriched with vegetable ash used do not show significant results in the vegetative development of the jiloeiro.
