Resumo: | The objective of this study was to produce silage from intercropped RR glyphosate tolerant corn (RR - Roundup Ready) and RR soybeans under Brazilian Cerrado conditions. The research was carried out in off-season between February and June 2015, in Rio Verde, Goiás (Brazil). In the experimental period the rainfall was 865 mm and the average temperature of 23.7°C. Two trials were performed. The first had corn rows spaced in 1 m with a row of soybeans in the interrow. The second had double corn rows interspersed with one row of soybeans, all spaced in 0.50 m. In both trials, we used a randomized block design, in a 2x2+3 factorial scheme, with four replications. Primary factor consisted of two types of pre-sowing fertilization: one only in corn rows and the other over the total area. The secondary factor corresponded to two soybean varieties: medium and late cycle variety. In addition, three control treatments were made: one of corn and two of soybeans. The corn cutoff point was at the hard farinaceous stage when the milk line reaches half the grain, and in the sole crop soybean at the R5.5 final phase of grain filling. Silage was stored in PVC experimental silos for 60 days. The intercropped treatments, in both spatial arrangements, promoted increases in neutral detergent fiber and acid detergent fiber contents. Soybean monoculture presented high values of crude protein and ethereal extract. There were higher effluent losses in medium-cycle soybean variety silage when it was grown in single cropping. However, the lowest effluent losses were recorded for silages of medium-cycle soybean intercropped under a double row pre-sowing corn fertilization system. The soybeans mixed silages produced together with corn under off-season conditions did not yield satisfactory results. |

A pesquisa foi conduzida na safrinha entre fevereiro e junho de 2015, em Rio Verde, Goiás (Brasil). A pluviosidade do período experimental foi de 865mm e a temperatura média de 23,7°C. Realizou-se dois ensaios, adequando formas de adubação de semeadura, arranjo de plantas e cultivares. Utilizou-se delineamento em blocos casualizados, em fatorial 2x2+3, com quatro repetições, sendo o fator primário duas modalidades de adubação de semeadura na linha: somente no milho, e em área total; o fator secundário correspondeu a duas variedades de soja: ciclo médio e tardio; mais três testemunhas: uma de milho e duas de soja. O ponto de corte do milho foi no estádio farináceo duro quando a linha do leite atinge metade do grão, e na soja em monocultivo no estádio fenológico R5.5, fase final de enchimento de grãos. Armazenou-se a silagem em silos experimentais de PVC por 60 dias. Os tratamentos de consórcio em ambos os arranjos aumentaram os teores de fibra em detergente neutro e fibra em detergente ácido. Os monocultivos de soja obtiveram valores elevados de proteína bruta e extrato etéreo. Ocorreu maior perda por efluente na silagem da variedade de soja de ciclo médio cultivada em monocultivo. No entanto, as menores perdas por efluente foram registradas para silagens de culturas de soja de ciclo médio consorciadas sob um sistema de fertilização pré-semeadura de linha de milho, no arranjo de linha dupla. A inserção de soja para produzir silagens mista juntamente com o milho em condições de safrinha não teve resultados satisfatórios.EDUFU2019-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3986910.14393/BJ-v35n6a2019-39869Bioscience Journal ; Vol. 35 No. 6 (2019): Nov./Dec.; 1886-1898Bioscience Journal ; v. 35 n. 6 (2019): Nov./Dec.; 1886-18981981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39869/27475Brazil; ContemporaryCopyright (c) 2019 Isabella Sichierski Cardoso, Adriano Jakelaitis, Karolyna Oliveira Marques, Katia Cylene Guimarães, Leandro Spíndola Pereirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCardoso, Isabella SichierskiJakelaitis, AdrianoMarques, Karolyna OliveiraGuimarães, Katia CylenePereira, Leandro Spíndola2022-01-25T21:20:08Zoai:ojs.www.seer.ufu.br:article/39869Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-25T21:20:08Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
