CRESCIMENTO INICIAL DE MUDAS DE Punica granatum L.EM DIFERENTES SUBSTRATOS

Abstract

The pomegranate (Punica granatum L.) has been of great importance in the pharmaceutical industry because of its great medicinal potential, Besides being widely used as a fruit and ornamental plant, adapted to arid climate regions. There is little research on different aspects of culture. Thus, the objective of this experiment was to evaluate the initial growth of pomegranate seedlings on substrates consisting of soil, bovine manure and sawdust. For this purpose, an experiment was carried out in a protected environment, with seven treatments consisting of different soil (SO), manure (E) and sawdust (SE), T1 = 20% SO, 40% E, 40% SE; T2 = 38% SO, 22% E, 40% SE; T3 = 43% SO, 40% E, 17% SE; T4 = 60% SO, 00% E, 40% SE; T5 = 60% SO, 19% E, 21% SE; T6 = 64% SO, 36% E,%; T7 = 80% SO, 13% E, 07%SE. The design was completely randomized with seven treatments, with four blocks and three seedlings per experimental unit The height of seedlings, stem diameter, number of branches, number of leaves, leaf area, leaf dry matter mass, stem dry matter mass and root dry matter mass were evaluated at 50 days after transplanting. The data were submitted to analysis of variance and regression appropriate for mixing experiments. Increasing the proportion of sawdust to the substrates results in lower seedling growth. Increasing the proportion of soil provides greater growth of seedlings. The best substrate estimated for the formation of pomegranate seedlings consists of 80% soil, 5.5% sawdust and 14.5% bovine manure.
