Manejo, produção e qualidade de açaí de terra firme associado à densidade de touceira e adubação orgânica sob sistema agroflorestal

Abstract

The great interest in the cultivation of açaizeiro (Euterpe oleraceae Mart.) in terra firme areas is due to the great growth in demand for the fruit. However, information on management in terra firme areas, in different regions of the country, is scarce. Lower density of stems in the clump, associated with organic fertilization, can increase the productivity and quality of açaí fruits. Thus, this research aims to evaluate the development, production and quality of açaí de terra firme associated with different clump densities and fertilization management in the agroforestry system. The Composite Forest at Fazenda Escola de São Luís of Universidade Estadual-UEMA, was located in Pará, through the experiment, Agricultural System: cultivating açaíS plant species, the cupuaçu tree BRS Carimbó (Theobroma grandiflorum); and banana varieties (Musa sp). The design was completely randomized in a 5x2 factorial scheme, in which the first factor is for the group of thinning levels of five stems (2, 3, 4, 5 and 6 stems), and the second for the types of fertilization and mineral). com 3. Data after their normality were selected for Analysis of Variance) and as means of Scott & K test level evaluation criteria of 5% probability, using the AgroEstat software. Mineral fertilization associated with a density of 4 stems per clump was responsible for presenting clusters with good fruit quality. The density of stipe adoption resulted in delayed development and low productivity of the adopted fertilization management.
