Avaliação agronômica de um sistema agroflorestal composto de progênies de cupuaçuzeiro e híbrido de coqueiro no município de Moju-PA

Abstract

Research was conducted in ownership Sococo S.A. Amazon Agroindustry, in the Moju city, Para state, Brazil, geographic coordenates 02º 07’00” S and 48º of longitude W, in Oxisol, medium texture, with the aim of to study an agroforestry system with half-brothers progenies of cupuassu and coconut regarding to resistance to witches´broom, vegetative growth, fruit and litter production; coconut production in SAF and in monoculture and soil chemical characteristics on four differents management systems. The experimental design was randomized blocks with five treatments and four replicates: Treatment 1 – coconut and cupuassu progenies of clone 174; Treatment 2 – coconut and cupuassu progenies of clone 186; treatment 3 – coconut and cupuassu progenies of clone 215; Treatment 4 – coconut and cupuassu progenies of clone 286; Treatment 5 – coconut and control progeny formed from seeds of unknown parents. Cupuassu plants were placed on alterned streets of coconut plantation with space of 14.8 m between lines and 8.5 m between plants (79.5 plants.ha-1). In all evaluated variables (resistance to witches´broom, vegetative growth, fruit and litter production) the progenies were similar to control and produced in the first three crops an average 3.89 fruits.plants-1.crop-1 and was provided to the soil annualy 1714.20 Kg.ha-1 of litter, improving the soil chemical properties and increasing the coconut production.
