Resumo: | With the intensification of pig farming systems, in Brazil, the production of swine waste has increased considerably, leading to water and soil contamination, due to its improper release. Pig slurry composting is an alternative that can be used in order to avoid or reduce negative impacts, especially for producers with physically limited farm areas, or those who intend to increase the number of animals in their production units. This study aimed at evaluating the influence of pig slurry compost doses on the agronomic characteristics and grain yield of proso millet. A randomized blocks design experiment was installed with four replications and five treatments: control without fertilization, control with mineral fertilizer (NPK) and pig slurry compost doses (4.0 Mg ha-1, 8.0 Mg ha-1; 12.0 Mg ha-1). The pig slurry composting increased the dry matter yield, number of grains per plant and grain yield of proso millet, when compared to the control with or without mineral fertilizer. The proso millet yield, at the doses of 8.0 Mg ha-1 and 12.0 Mg ha-1 of pig slurry, was superior than for both the control without fertilization and the control with the recommended mineral fertilizer, with the latter reaching a maximum agronomic efficiency at the dose of 8.0 Mg ha-1. |

A compostagem de dejetos líquidos de suínos surge como alternativa para evitar ou reduzir impactos negativos, principalmente para produtores com limitação de áreas físicas, ou que visem ao aumento do número de animais na unidade de produção. Objetivou-se avaliar o efeito de doses de compostagem de dejetos líquidos de suínos nas características agronômicas e produtividade de grãos de painço. O delineamento experimental foi em blocos ao acaso, com quatro repetições e cinco tratamentos, os quais consistiram em testemunha sem adubação, testemunha com adubação mineral (NPK) e doses de compostagem de dejetos líquidos de suínos (4,0 Mg ha-1; 8,0 Mg ha-1; 12,0 Mg ha-1). A compostagem de dejetos líquidos de suínos promoveu incremento na produção de massa seca, número de grãos por planta e produtividade de grãos de painço, em relação às testemunhas sem adubação e com aubação mineral. A resposta do painço para produtividade, nas doses de 8,0 Mg ha-1 e 12,0 Mg ha-1, mostrou-se superior à das testemunhas sem adubação e com adubação mineral recomendada para a cultura, sendo que esta apresenta máxima eficiência agronômica para a dose de 8,0 Mg ha-1.Escola de Agronomia - Universidade Federal de Goiás2016-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/38457Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 1, Jan./Mar. 2016; 80-88Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 1, jan./mar. 2016; 80-88Pesquisa Agropecuária Tropical; v. 46, n. 1, jan./mar. 2016; 80-881983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/38457/20861Silva, Alieze Nascimento daBasso, Claudir JoséMuraro, Dionei SchmidtOrtigara, CíceroPansera, Edivaninfo:eu-repo/semantics/openAccess2020-07-13T17:49:09Zoai:ojs.revistas.ufg.br:article/38457Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T17:49:09Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false |
