Influence of different substrates in the initial development of pitangueira changes.

Abstract

The pitangueira (Eugenia uniflora L.) is a tree species, fruitful, native to the Atlantic Forest, but adapts to practically all climates. Its main form of obtaining seedlings for domestic plantations, occurs satisfactorily through seeds. It has been increasingly used in medical, cosmetic and food industries. The objective of this study was to evaluate the initial development of pitangueira seedlings submitted to substrates of animal and mineral origin. The development of the seedlings was evaluated in different substrates, being: T1 (blue) - soil of subsoil and sand 3:1, T2 (yellow) - soil of subsoil, sand and NPK 3:1 and 400 g of NPK for each 10kg of subsoil , T3 (red) - Subsoil soil, sand and cow dung 3:1:1, T4 (pink) - Subsoil soil, sand and 3:1 : ½ fish meal. The experimental design was used in randomized blocks with 4 treatments, 4 replicates per treatment and 5 plants per replicate. The variables analyzed were a percentage of germination, IVE, neck diameter, height and leaf number. The study shows that cow manure is the most efficient in the initial development of pitangueira.
