Resumo: Considering the importance of cactus pear as an alimentary alternative for the herd of cattle of the Brazilian semiarid region and the effect of crop spacing among plants, this study aimed to evaluate the morphometry, yield and chemical-bromatological composition of cactus pear genotypes, under different cropping densities. The experimental design was completely randomized blocks, in a 3x4 factorial scheme. Treatments consisted of a combination of three cactus pear genotypes (Gigante, Redonda and Miúda) and four cropping densities (10,000 plants ha-1; 20,000 plants ha-1; 40,000 plants ha-1; and 80,000 plants ha-1), with three replications. The cactus pear genotypes reacted differently, regarding morphometry, yield and chemical-bromatological composition, and, regardless of the species, the denser planting increased yield (tons ha-1). The Miúda palm presented the highest dry matter yield and consequently the greater accumulation of total digestible nutrients, raw protein and water per hectare, as well as the highest in vitro dry matter digestibility.

O delineamento experimental utilizado foi em blocos completos casualizados, em esquema fatorial 3x4. Os tratamentos constituíram-se da combinação de três genótipos de palma forrageira (Gigante, Redonda e Miúda) e quatro densidades de cultivo (10.000 plantas ha-1, 20.000 plantas ha-1, 40.000 plantas ha-1 e 80.000 plantas ha-1), com três repetições. Os genótipos de palma forrageira apresentaram comportamentos diferentes, quanto à morfometria, produtividade e composição químico-bromatológica, e, independentemente da espécie, o plantio adensado elevou a produtividade (toneladas ha-1). A palma Miúda apresentou maior produtividade de matéria seca e, consequentemente, maior acúmulo de nutrientes digestíveis totais, proteína bruta e água por hectare, bem como maior digestibilidade in vitro da matéria seca.Escola de Agronomia - Universidade Federal de Goiás2014-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/26524Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 4, Oct./Dec. 2014; 424-433Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 4, out./dez. 2014; 424-433Pesquisa Agropecuária Tropical; v. 44, n. 4, out./dez. 2014; 424-4331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/26524/17604Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessCavalcante, Lucas Aroaldo DantasSantos, Gladston Rafael de ArrudaSilva, Laerte Marques daFagundes, Jailson LaraSilva, Mônica Alixandrina da2020-07-13T15:04:47Zoai:ojs.revistas.ufg.br:article/26524Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:04.644320Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
