Resumo: The objective of the work was to evaluate production and decomposition of biomass, accumulation and cycling of nutrients by single, intercropped or polyculture cover crops. The study was conducted in two experimental areas, at the Cedeteg Campus, characterized as a low fertility area, and a school farm, characterized as a high fertility area, belonging to UNICENTRO in Guarapuava, PR. The design used was randomized blocks, with 3 treatments and 4 repetitions, being the treatments: single cultivation, intercropping and polyculture of winter cover plants. Biomass production, accumulation of nutrients in biomass (N, P, K, Ca and Mg), C / N ratio, decomposition, and nutrient release were evaluated. For low fertility soils: single cultivation showed higher biomass production and concentration of P and K; for C/N ratio there was no difference; single and polyculture cultivation showed higher residual biomass at 120 days after management; single cultivation had a shorter half life time for most nutrients. For soils with high fertility: consortium and polycultures showed higher biomass production and Mg accumulation; polycultivation presented a greater accumulated amount of N, the consortium accumulated a greater amount of Ca; single cultivation presented a lower C/N ratio and a half life span for nutrients. Single cultivation has an aptitude for nutrient cycling and an increase in biomass in low fertility soils. For highly fertile soils, the consortium and polyculture are options for nutrient cycling and high biomass production.

El estudio se realizó en dos áreas experimentales, en el Campus Cedeteg, caracterizado por un área de baja fertilidad, y una granja escolar, caracterizada como un área de alta fertilidad, pertenecientes a UNICENTRO en Guarapuava, PR. El diseño utilizado fue bloques al azar, con 3 tratamientos y 4 repeticiones, siendo los tratamientos: cultivo individual, intercalado y policultivo de plantas de cobertura invernal. Se evaluó la producción de biomasa, la acumulación de nutrientes en la biomasa (N, P, K, Ca y Mg), la relación C/N, la descomposición y la liberación de nutrientes. Para suelos de baja fertilidade: el cultivo individual mostró mayor producción de biomasa y concentración de P y K; para la relación C/N no hubo diferencia; el cultivo individual y policultivo mostró mayor biomasa residual a 120 días después de la manipulación; el cultivo individuale tuvo una vida media más corta para la mayoría de los nutrientes. Para suelos con alta fertilidad, el consorcio y policultivo mostraron mayor producción de biomasa y acumulación de Mg; el policultivo presentó una mayor cantidad acumulada de N, el consorcio acumuló una mayor cantidad de Ca; el cultivo individual presentó una menor relación C/N y una menor vida media de los nutrientes. El cultivo individual tiene aptitud para el ciclo de nutrientes y un aumento de la biomasa en suelos de baja fertilidad. El consorcio y el policultivo son opciones para el ciclo de nutrientes y una alta producción de biomasa para suelos fértil.O objetivo do trabalho foi avaliar a produção e decomposição da biomassa, acúmulo e ciclagem de nutrientes pelo cultivo solteiro, consorciado ou policultivo de plantas de cobertura. O estudo foi conduzido em duas áreas experimentais, no Campus Cedeteg, caracterizada como área de baixa fertilidade, e fazenda escola, caracterizada como área de alta fertilidade, pertencentes a UNICENTRO em Guarapuava, PR. O delineamento utilizado foi de blocos ao acaso, com 3 tratamentos e 4 repetições, sendo os tratamentos: cultivo solteiro, consórcio e policultivo de plantas de cobertura de inverno. Foram avaliadas a produção de biomassa, acúmulo de nutrientes na biomassa (N, P, K, Ca e Mg), relação C/N, decomposição, e liberação de nutrientes. Para solos de baixa fertilidade: o cultivo solteiro apresentou maior produção de biomassa e concentração de P e K; para relação C/N não houve diferença; o cultivo solteiro e policultivo apresentaram maior residual de biomassa aos 120 dias após o manejo; o cultivo solteiro apresentou menor tempo de ½ vida para a maioria dos nutrientes. Para solos de elevada fertilidade: o consórcio e policultivo apresentaram maior produção de biomassa e acúmulo de Mg; o policultivo apresentou maior quantidade acumulada de N, o consórcio acumulou maior quantidade de Ca; o cultivo solteiro apresentou menor relação C/N e menor tempo de ½ vida para nutrientes. O cultivo solteiro apresenta aptidão na ciclagem de nutrientes e incremento de biomassa em solos de baixa fertilidade. O consórcio e policultivo são opções para ciclagem de nutrientes e elevada produção de biomassa em solos férteis.Research, Society and Development2020-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/787010.33448/rsd-v9i9.7870Research, Society and Development; Vol. 9 No. 9; e779997870Research, Society and Development; Vol. 9 Núm. 9; e779997870Research, Society and Development; v. 9 n. 9; e7799978702525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7870/6999Copyright (c) 2020 Edson Lucas Camilo; Marcelo Marques Lopes Müller; Leandro Rampim; Marcelo Luiz Camilo; Weslei Ricardo Graffunder; Jonas Luiz Kulik; Cristiano Andre Potthttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCamilo, Edson LucasMüller, Marcelo Marques LopesRampim, LeandroCamilo, Marcelo Luiz Graffunder, Weslei RicardoKulik, Jonas LuizPott, Cristiano Andre2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7870Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:27.835795Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
