SUBSTRATES AND DOSES OF CONTROLLED RELEASE FERTILIZER PRODUCTION OF DUMB Acai ?? (Euterpe oleracea Mart.)

Abstract

This work aims to evaluate different substrates and doses of controlled-release fertilizer in the seedling production of açaí. For this, we performed this experiment under conditions of house * Vegeta in Orchard, Federal University of Lavras (MG) from November 2002 to July 2003 0 experimental design was a randomized complete block in factorial 6 x 2 design with four replications and three plants per plot. The treatments consisted of doses of controlled-release fertilizer (15-10-10): 0; 1.0; 2.0; 4.0; 6.0 and 8.0 kg.m-3 substrate and substrates: A (FYM + coffee + charcoal + sand and soil in the ratio of 1: 1: 1: 1: 2 v / v) and substrate B (Plantmax + coffee + saw + p6 sand and soil in the ratio of 1: 1: 1: 1: 2 v / v the variables were seedling height, / lamer ° sheets, = feria drought shoot and roots.'s controlled-release fertilizer (15-10-10) up to a dose of 4 kg.m3 substrate and the use of substrate B (composed of Plantmax, coffee husk, p6 saw, sand and soil at 1: 1: 1: 1: 2 v / v) proved to be a good alternative substrates for producing seedlings açaizeiro quality.
