Agronomic characteristics and chemical composition of the forage palm for different cropping systems
2018
espanolObjetivou-se, com este trabalho, avaliar as caracteristicas agronomicas e composicao quimica em relacao a diferentes sistemas de plantio da cultura da Palma Forrageira (Opuntia ficus-indica (L.) P. Mill). O delineamento experimental utilizado foi em blocos completos casualisados com arranjo fatorial 2x2x2 com 4 repeticoes. Os fatores corresponderam a plantas expostas ao sol ou sombreadas (por plantas de Spondias spp.), posicao de plantio do cladodio da Palma Forrageira (face larga voltada para leste/oeste ou norte/sul) e com ou sem adubacao orgânica com esterco de bovino de corte. A Palma Forrageira foi plantada com espacamento de 1,0m x 0,5m em Quixada, Ceara, Brasil. O experimento foi conduzido no periodo de novembro de 2003 a novembro de 2007, sendo realizado dois corte. Foi avaliada a producao de massa verde a cada dois anos e a producao de massa seca. A composicao quimica foi avaliada no ultimo corte. O sombreamento com Caja (Spondias ssp.) com 1,5m de altura promoveu reducao na producao de massa verde da palma forrageira, fato nao observado no segundo corte para massa seca. No segundo corte a palma que recebeu adubacao orgânica obteve maior producao de massa verde com 60,48t ha-1. A posicao de plantio do cladodio de palma forrageira influenciou a quantidade de fibra em detergente acido. A palma forrageira deve ser plantada sem sombreamento, com direcionamento da parte mais larga do cladodio no plantio leste/oeste e com adubacao orgânica de esterco bovino. EnglishThe objective of this study was to evaluate the agronomic characteristics and chemical composition for different cropping systems of the culture of forage palm (Opuntia ficus-indica (L.) P. Mill). The experimental design was a randomized complete block design with factorial arrangement 2x2x2 with four repetitions. The factors corresponded to plants exposed to the sun or shaded (by Spondias spp.), Cladodes planting position of forage palm (facing wide face east/west or north/south) and with or without organic fertilization with cattle manure cutting. The Forager Palma was planted with a spacing of 1,0m x 0,5m in Quixada, Ceara, Brazil. The experiment was conducted from November 2003 to November 2007, being held two cutting. green mass production every two years and the dry matter production was evaluated. The chemical composition was evaluated in the final cut. Shading with Caja (Spondias ssp.) With 1,5m tall promoted reduction in green mass production of forage cactus, which was not observed in the second cut to dry mass. In the second cut palm that received organic fertilizer obtained higher green mass production with 60,48t ha-1. Planting position of the spineless cactus cladodes influenced the amount of acid detergent fiber. The spineless cactus must be planted without shading, with direction of the widest part of cladodes in the east/west planting and organic fertilization of manure.
