Resumo: This study aimed to evaluate mechanical and chemical methods of forage dehydration in the production of black oat pre-dried silage (Avena strigosa Schreb) under different dehydration times. The experiment was conducted in a randomized block experimental design with five replications and arranged in a 2 x 6 factorial scheme. We assessed two methods of dehydration, mechanical and chemical, over six dewatering times, being made at 0, 3, 6, 9, 12, and 15 days after cutting or application of glyphosate. Harvest took place at 88 days after emergence, at pre-flowering. We evaluated dry biomass production at harvest, dry matter losses during dehydration in the field, losses during ensiling, gauging effluent output, and pre-dried silage chemical composition. There was an interaction between dehydration method and harvest time for most of the production characteristics. Chemical dehydration showed an enhanced dry matter recovery at the field level, however, unsuitable for pre-dried silage. The longer the dehydration period, the lower the losses for both analyzed methods; nevertheless, the chemical method reached unsatisfactory DM contents to produce good quality silage.

O experimento foi realizado em delineamento de blocos ao acaso, com 5 repetições, em esquema fatorial 2 x 6, sendo dois métodos de desidratação, mecânico e químico, sobre seis tempos de desidratação, sendo 0, 3, 6, 9, 12 e 15 dias após o corte ou aplicação do herbicida glifosato. A colheita se deu aos 88 dias após emergência, em estádio de pré-florescimento. Foram avaliadas produção de fitomassa seca no momento da colheita, perdas de fitomassa seca durante a desidratação à campo, perdas durante a ensilagem, com aferição da produção de efluentes, além da composição bromatológica da silagem pré-secada. Houve interação entre método de desidratação x época de colheita, para a maioria das características de produção. O método de desidratação químico apresentou maior recuperação de fitomassa seca à nível de campo. O método de desidratação químico não apresentou teor de DM ideal para silagem pré-secada, porém, apresentou maior recuperação de fitomassa seca. O maior tempo de desidratação propiciou menores perdas em ambos os métodos de desidratação, mas o método químico não atingiu DM necessária para produção de silagem de qualidade, levando também a uma silagem de menor qualidade.UEL2017-05-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2600610.5433/1679-0359.2017v38n2p981Semina: Ciências Agrárias; Vol. 38 No. 2 (2017); 981-996Semina: Ciências Agrárias; v. 38 n. 2 (2017); 981-9961679-03591676-546Xreponame:Semina.
