Matéria e nutrientes da parte aérea de adubos verdes em cultivos exclusivo e consorciado

Abstract: Shoot biomass and nutrients of green manure in monoculture and intercropped systemsThe objective of this work was to verify the effects of different cover crops using legumes (pigeon pea, sunn hemp, jack bean and velvet bean) in monoculture and intercropped systems of grass (pearl millet), legumes/grass and a fallow area, on phytomass production and nutrient return. The experimental design was randomized blocks with ten treatments (pigeon pea, sunn hemp, jack bean, velvet bean, pearl millet, pigeon pea + pearl… Show more

“…This is in agreement with a study by Rodrigues et al (2012) who found the highest levels of calcium in legumes compared with a grass species. Duarte Junior and Rabbit (2008) observed higher Ca accumulation in bean-to-pig who had the equivalent to 197 kg ha-1 of Ca, while levels in crotalaria (123 kg ha -1 ) and mucuna (95 kg ha -1 ) did not differ significantly.…”

“…Thus, the use of leguminous species in green manure does not necessarily provide increased N cycling capacity compared to the use of a grass or oleginosa species. In this sense, RODRIGUES et al (2012), when comparing different compositions of green manure, found that nitrogen content varied more than 55% between legume species, but for some species, there was no significant difference when compared to grass (millet). They found N levels of 35.1, 31.0, 21.9, 16.4 and 13.3 g kg -1…”

“…The lower productivity in uncovered soil may be associated to higher water loss through evaporation, percolation and volatilization, as well as lower nutrient cycling and lower organic matter contents (RODRIGUES et al, 2012). Passion fruit is highly demanding in nutrients and this is one of the factors that most contributes to fruit productivity and quality (COSTA et al, 2008), mainly in tropical soils.…”

“…Entretanto, também existem relatos de produtividades superiores de FS (CARNEIRO et al, 2008;RODRIGUES et al, 2012;ARAÚJO et al, 2015). A diferença dos resultados nas regiões de Cerrado, em parte está relacionada às diferenças de época de semeadura, manejo, do volume de chuvas no decorrer do crescimento e do desenvolvimento das plantas de cobertura.…”

“…Dentre as diversas espécies, com finalidade agronômica para produção específica de palhada, o milheto e o guandu-anão têm sido as espécies mais estudas no Cerrado (KLIEMANN et al, 2006;NUNES et al, 2006;CARNEIRO et al, 2008;TORRES et al, 2008;CALVO et al, 2010;PACHECO et al, 2011;RODRIGUES et al, 2012;ARAÚJO et al, 2015). O desempenho superior dessas espécies como formadoras de palhada se deve preferencialmente pela adaptação ao clima e solo do Cerrado, ao potencial de produção de fitomassa seca e pela capacidade de extração e reciclagem de nutrientes.…”
