Fertilidade do solo e produtividade de milho em sistemas de adubação verde no norte de Minas Gerais

Abstract: RESUMO -Baixas produtividades e deficiências de nitrogênio coexistem na cultura do milho, sobretudo em sistemas voltados para a agricultura de subsistência. Diante disso, com esta pesquisa buscou-se avaliar os efeitos da utilização de diferentes adubos verdes em sucessão com o milho, sob manejo de cultivo mínimo e convencional, quanto ao aporte de nutrientes ao solo, ao estado nutricional e às características produtivas do milho para a produção de espigas. O experimento foi conduzido em campo, no Norte de Mina… Show more

“…A study carried out in Brazil evaluated different green manures in rotation with maize under two managements, minimum or conventional tillage [64]. The green manures used were as follows: Crotalaria juncea, Canavalia ensiformes, Rafhanus sativus, mixed species (cocktail) with Crotalaria juncea, Canavalia ensiformes and Rafhanus sativus, and weeds (control) [64]. The green manures treatments had maize yield higher than the control with weeds, with average of 2.8 t/ha of peeled green ears [64].…”

The green manures treatments had maize yield higher than the control with weeds, with average of 2.8 t/ha of peeled green ears [64]. Another study, in the same region, evaluated the effect of N topdressing absence, pre-cultivation of C. juncea and topdressing with ammonium sulfate or urea on maize yield produced for silage [65].…”

“…No Brasil, essa planta tem sido cultivada nas regiões Sul, Sudeste e Centro-Oeste como adubo verde e planta de cobertura em sistemas de cultivos conservacionistas, a exemplo do plantio direto (CRUSCIOL et al, 2005), e vem se expandindo para regiões em que predominam altas temperaturas. No município de Jataí (Goiás), a cultura do naboforrageiro foi promissora na produção de biomassa para cobertura de solo (SOUZA et al, 2008); em Montes Claros no Norte de Minas Gerais, o cultivo dessa espécie como adubo verde proporcionou incrementos na produtividade da cultura sucessora (VALADARES et al, 2012).…”

“…These results came from different factors, that have influenced the systems. The first is the nutrient deficiency, by the recycling performed by the maize + legumes and weeds, which did not allow normal development of maize and as a result, its growth and production were adversely affected (Valadares et al, 2012). These findings do not invalidate the results achieved in this test, as they are directed to a different reality, that is, organic corn production by family farmers with no synthetic inputs and cultural practices, in agreement with results obtained by Carpentieri-Pipolo et al (2010).…”
