ADUBAÇÃO ORGÂNICA E MINERAL EM MUDAS DE Punica granatum L.

Abstract

The pomegranate (Punica granatum L.) has been widely used as a fruit, ornamental plant in parks and gardens decorations and presents important medicinal properties, being a huge agronomic and pharmacological potential of plant, having a favorable adaptation to arid regions little study is conducted on the culture on the above the aim of this work was to study the different NPK concentrations and cattle manure in the initial growth of seedlings Punica granatum L. the experiments were divided into two: one with mineral concentrations and the second with concentrations organic which were conducted in a protected environment at the Department of Soils and Rural UFPB the CCA Engineering, located in Areia - PB. Treatments with organic fertilization were: T1 = control without fertilization; T2 = 25% of the concentration; T3 = 50% of the concentration; T4 = 75% of the concentration; T5 = 100% with cattle manure at the rate of 0.5 kg of soil. With mineral fertilizer were: T1 = control without fertilization; T2 = 25% of the concentration; T3 = 50% of the concentration; T4 = 75% of the concentration; T5 = 100% consisting concentration of 150, 100 and 100 mg of N, P and K per 0.5 kg of soil. After 75 days after transplanting the following variables were evaluated: seedling height, stem diameter, number of branches and leaves, total leaf area and dry weight of shoot and root. From the data obtained during the production of pomegranate seedlings process, possible to check the growth in shoot height and diameter of the seedlings in the treatments with increasing concentration. Seedlings of pomegranate respond positively to mineral fertilization with NPK and concentration 100% of cattle manure provides greater vertical growth, diameter and number of leaves.
