Resumo: | The current study aimed to evaluate the effects of different tillage systems on soil organic matter (SOM) contents and green corn yield (total ear weight) of an Argissolo Vermelho-Amarelo (Ultissol) in Coastal tablelands of northeast Brazil. The experiment was arranged as a strip plot design with three replications. Three tillage practices [conventional tillage (CT), minimum tillage (MT) and no-tillage (NT)] were laid out as a whole plot each (830 m²). Then, each plot was equally split into 12 experimental units (60 m²), distant 1 x 10 m from each other, where in four cover crops [pigeon pea (Cajanus cajan (L.) Millsp.), sunn hemp (Crotalaria juncea L.), beans (Phaseolus vulgaris) and peanut (Arachis hypogeae) were seedling previous to corn cultivation. Neither cover crops, nor tillage practices affected SOM contents at 0.20 m depth. An exception was observed on beans plots in which CT resulted on the lowest SOM content (8.5 dag kg-1) at 0-10 cm soil layer. Regarding green corn ears yield, CT adoption also resulted in lower weight (4.11 t ha-1) than those on NT (7.65 t ha-1), regardless of cover crop. On the other hand, the influence of cover crops on green corn yield relied upon tillage practices. Peanuts and sunn hemp performed best to improve corn yield in CT; peanuts and beans increased by 14 % the green corn ears yield in MT, while sunn hemp resulted in the highest total ear weight (9.42 t ha-1). Linear correlation of Pearson was significant for SOM and productivity green maize ears in minimum tillage beans (p <0.001; r = 0.996). After four years of absence or reduced soil disturbance, there was no increase in SOM levels. The plowing appears to be important for increasing the entry of C soil and chemical protection SOM of Argissols mainly in the surface layer of Coastal tablelands in brazilian northeast. Although the NT did not provide higher levels of SOM, the yield of green maize in commercial was significantly higher when adopting conservation systems. |

O experimento foi disposto em faixas experimentais com três repetições. Três práticas de cultivo [cultivo convencional (CC), cultivo mínimo (CM) e plantio direto (PD)] foram arranjadas em faixas (830 m²). Então, cada faixa foi dividida igualmente em doze unidades experimentais (60 m²), distante entre si a cada 1 x 10 m, onde quatro culturas antecessoras [guandu (Cajanus cajan (L.) Millsp.) crotalária (Crotalaria juncea), feijão (Phaseolus vulgaris) e amendoim (Arachis hypogeae)] foram semeadas previamente ao cultivo do milho. As culturas antecessoras e as práticas de cultivo não afetaram os teores de MOS da profundidade de 0.20 m. Uma exceção foi observada nas parcelas com feijão no qual o CC resultou no menor teor de MOS (8.5 dag kg-1) na camada 0-10 cm. Em relação a produtividade das espigas de milho verde, a adoção do CC também resultou em menor peso (4,11 t ha-1) que no PD (7,65 t ha-1), independente da cultura antecessora. Por outro lado, a influência da cultura de cobertura sob a produtividade do milho verde foi dependente da prática de cultivo. Amendoim e crotalária saíram-se melhor para aumentar a produtividade do milho no CC; amendoim e feijão aumentaram em 14 % a produtividade das espigas de milho verde no CM, enquanto crotalária resultou no mais alto peso total das espigas (9,42 t ha-1). A correlação linear de Pearson foi significativo para a MOS e produtividade de espigas de milho verde com crotalária sob o cultivo mínimo (p <0,001; r = 0,996). Após quatro anos da ausência ou redução do revolvimento do solo, não houve aumento nos níveis de MOS. A aração parece ser importante para aumentar a entrada de C no solo e a proteção química da MOS em Argissolos, principalmente na camada superficial. Embora o PD não tenha fornecido níveis mais elevados de MOS, o rendimento de espigas comerciais de milho verde foi significativamente maior ao se adotar sistemas conservacionistas.EDUFU2019-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3980610.14393/BJ-v35n3a2019-39806Bioscience Journal ; Vol. 35 No. 3 (2019): May/June; 705-712Bioscience Journal ; v. 35 n. 3 (2019): May/June; 705-7121981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39806/26104Brazil; ContemporaryCopyright (c) 2019 Alceu Pedrotti, Renisson Neponuceno de Araújo Filho, Fernanda Cristina Caparelli de Oliveira, Sara Julliane Ribeiro Assunção, Francisco Sandro Rodrigues Holanda, Djail Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPedrotti, AlceuAraújo Filho, Renisson Neponuceno deOliveira, Fernanda Cristina Caparelli deAssunção, Sara Julliane RibeiroHolanda, Francisco Sandro RodriguesSantos, Djail2022-01-31T23:42:45Zoai:ojs.www.seer.ufu.br:article/39806Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-31T23:42:45Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
