Compactação do solo: efeitos nas características produtivas e morfológicas dos capins Piatã e Mombaça

Abstract: RESUMOAs gramíneas dos gêneros Panicum e Brachiaria, possuem participação expressiva nas pastagens da região do Cerrado, mas poucos trabalhos se referem aos seus comportamentos em condição de compactação do solo. Objetivou-se, então, avaliar o desenvolvimento das gramíneas forrageiras Brachiaria brizantha cv. Piatã e Panicum maximum cv. Mombaça sob níveis de compactação do solo. O experimento foi conduzido em casa de vegetação da Universidade Federal de Mato Grosso. O delineamento experimental utilizado foi in… Show more

“…Similar results have also been verified by Bonfim- Silva et al (2015), who obtained a reduction in SDM of 79.91% as Bd increased from 1.0 to 1.8 Mg m -3 in tests with jack bean, as well as Bonelli et al (2011) and Fagundes et al (2014), who observed reduction in the SDM of Mombasa grass and sugarcane with the increase of Bd, respectively, the latter with maximum point at Bd of 1.33 Mg m -3 .…”

“…Merotto Jr. andMundstock (1999) also described a decrease, according to soil compaction, in the wheat dry mass of aerial part. On the other hand, Bonelli et al (2011), when studying four bulk density levels (1.0; 1.2; 1.4 and 1.6 Mg m -3 ) verified that, for P. maximum 'Mombaça', the dry mass of aerial part presented high susceptibility to increasing bulk density, as also indicated by the resulting linear model found for this variable in this study.…”

“…Therefore, improvement of wheat production potential via soil management practices is one of the main research challenges facing the worldwide growing demand for food. In this sense, concerns on soil compaction are important, as soils may have appropriate nutrient contents, but because of physical conditions, efficiency of nutrient absorption by plants may be affected, resulting in yield decrease (Bonelli et al, 2011;Cabral et al, 2012).…”

“…A densidade do solo é considerada um importante indicador físico do solo pois interfere nas trocas gasosas, no crescimento do sistema radicular, na resistência a penetração e na dinâmica da água no solo, assim, manejos que não levem à grandes elevações são importantes para qualidade do solo (RESENDE et al, 2012;PEREIRA et al, 2013). Avaliando níveis de compactação do solo em Latossolo Amarelo, Bonelli et al (2011) verificaram respostas diferentes em capim mombaça e capim piatã. A produção de matéria seca da arte aérea da parte aérea do capim Mombaça foi reduzido com a elevação da compactação, sendo acentuada a redução de sua produção, quando a densidade do solo foi superior à 1,2 Mg m -3 .…”
