-The objective of this work was to evaluate the effect of intercropping systems between corn and tropical forages, at different cutting heights, on silage production, light interception, land use efficiency, intercropping competition factors, and pasture production. In the 2010/2011 and 2011/2012 crop seasons, two cultivation modalities were evaluated in the summer/autumn -monocropped corn with residual regrowth of signal grass (Urochloa decumbens) from the soil seed bank and corn intercropped with palisade grass (U. brizantha 'Marandu') -, in a factorial arrangement with two cutting heights for silage production -0.20 and 0.45 m. After corn silage harvest, the forages were grazed by lambs in a semi-feedlot system, in the winter/spring. Monocropped corn and 0.45-m cutting height both reduced dry matter yield for silage. Corn intercropped with palisade grass improved land use efficiency from 13 to 31% compared with monocropped crop, with land equivalent ratio greater than 1. Palisade grass showed higher light interception than signal grass over the intercrop period with corn and provided greater forage yield for lambs to graze during winter/spring. Corn intercropped with palisade grass, compared with monocropped corn, especially at the cutting height of 0.45 m, is a viable option for improving silage and pasture production, as well as land use efficiency in the integrated crop-livestock system.Index terms: Urochloa, Zea mays, cutting height, land equivalent ratio, light interception. Produção de silagem de milho consorciado com forrageiras tropicais em sistema de integração lavoura-pecuária com cordeirosResumo -O objetivo deste trabalho foi avaliar o efeito de cultivos consorciados entre milho e forrageiras tropicais, em diferentes alturas de corte, sobre a produção de silagem, a interceptação luminosa, a eficiência de uso da terra, os fatores de competição do consórcio e a produção da pastagem. Foram avaliados, nas safras 2010/2011 e 2011/2012, duas modalidades de cultivo no verão/outono -monocultivo de milho com rebrota do banco de sementes de capim-braquiária (Urochloa decumbens) e milho consorciado com capim-marandu (U. brizantha 'Marandu') -, em arranjo fatorial com duas alturas de corte para ensilagem -0,20 e 0,45 m. Após a colheita do milho para ensilagem, as forragens foram pastejadas por cordeiros semi-confinados, no inverno/ primavera. O monocultivo do milho e a altura de corte a 0,45 m reduziram a produtividade de matéria seca para ensilagem. O milho consorciado com capim-marandu melhorou a eficiência de uso da terra de 13 para 31%, comparado ao monocultivo do milho, com relação de equivalência de uso da terra maior que 1. O capimmarandu apresentou maior interceptação luminosa que o capim-braquiária, ao longo do período de consórcio com o milho, e proporcionou maior produção de forragem para o pastejo pelos cordeiros durante o inverno/ primavera. O milho consorciado com capim-marandu, comparado ao monocultivo do milho, principalmente na altura de corte de 0,45 m, é uma opção viável para aument...

“…Besides the production of silage using monocropped corn, the combination of this annual crop with tropical forage grasses has been used to increase total dry matter production during the year (Leonel et al, 2009;Borghi et al, 2013) and to recover degraded pastures (Mateus et al, 2016).

“…The Cerrado biome covers approximately 205 million hectares and is mostly suitable for growing annual cash crops (Sano et al, 2008). However, these types of crops are rarely cultivated in the low-altitude areas of the Cerrado, which, instead, are dominated by degraded pastures, with very low forage supply in the off-season because of climate conditions (Mateus et al, 2016). In Brazil, approximately 80 million hectares of pastures are degraded, i.e., have low forage production (Janusckiewicz et al, 2015).…”

-The objective of this work was to compare the yield and nutritive value of the silage of corn intercropped with palisade grass (Urochloa brizantha 'Marandu') or guinea grass (Megathyrsus maximus 'Tanzânia') with those of the silage of monocropped corn, as well as to evaluate the pasture established in the intercropping systems during two growing seasons (2010-2011 and 2011-2012), in low-altitude Brazilian Cerrado. The treatments consisted of three cropping systems: monocropped corn, corn intercropped with palisade grass, and corn intercropped with guinea grass, with four replicates. Intercropping decreased corn forage dry matter yield for silage; however, due to the addition of grass, total dry matter yield (corn + grass) was similar between treatments. Intercropping also did not negatively affect corn production components and morphological characteristics. The cropping systems provided silages with good nutritive values, and the inclusion of tropical forages increased the silage fiber contents. Intercropping corn with tropical perennial grasses is a viable option for producing large quantities of silage with good nutritive value. The forage yield (silage + pasture) of these intercropping systems is similar to that of monocropped corn in tropical regions and has the advantage of providing a pasture in the off-season.Index terms: Megathyrsus maximus, Urochloa brizantha, Zea mays, Brazilian Cerrado, intercropped system. Produtividade e valor nutritivo da silagem de milho em consórcio com gramíneas perenes tropicaisResumo -O objetivo deste trabalho foi comparar a produtividade e o valor nutritivo da silagem de milho em consórcio com capim-marandu (Urochloa brizantha 'Marandu') ou capim-tanzânia (Megathyrsus maximus 'Tanzânia') aos da silagem de milho em monocultivo, bem como avaliar a pastagem estabelecida nos sistemas consorciados durante duas estações de cultivo (2010-2011 e 2011-2012), em Cerrado brasileiro de baixa altitude. Os tratamentos consistiram de três sistemas de cultivo: milho em monocultivo, milho em consórcio com capim-marandu e milho em consórcio com capim-tanzânia, em quatro repetições. O cultivo consorciado diminuiu a produtividade de massa seca de forragem de milho para silagem; porém, devido à adição do capim, a produtividade total de massa seca (milho + capim) foi similar entre os tratamentos. O consórcio também não afetou negativamente os componentes de produção e as características morfológicas do milho. Os sistemas de cultivo produziram silagens com bons valores nutricionais, e a inclusão de forrageiras tropicais aumentou os teores de fibra na silagem. O consórcio do milho com gramíneas perenes tropicais é viável para a produção de grandes quantidades de silagem com boa qualidade nutricional. A produção de forragem (silagem + pastagem) desses sistemas consorciados é similar à do milho em monocultivo em regiões tropicais e tem a vantagem de proporcionar pastagem na entressafra.Termos para indexação: Megathyrsus maximus, Urochloa brizantha, Zea mays, Cerrado, sistema consorciado.

“…No-tillage system (NTS) is currently a good alternative for the sustainability of tropical farming systems, in particular with a view to erosion reduction, nutrient cycling, water storage, and long-term improvements of the soil physical and chemical quality (Mateus et al, 2016). However, most grass crops of commercial interest produce only insufficient amounts of residue for an appropriate mulch cover of the soil (Allen et al, 2007).…”

Autumn maize intercropped with tropical forages can raise the amount of crop residues and improve nutrient cycling, favoring subsequent soybean crop. The objective of this study was to evaluate the effect of forms of implementation of intercropping of irrigated autumn maize with tropical forages on yield, decomposition, nutrient accumulation and release, and on the ratio of lignin/total N of forage residues, yield components, and grain yield of subsequent soybean, and on soil physical and chemical properties, under no-tillage in lowland Cerrado. The experiment was arranged in randomized blocks in a factorial (4 × 3 + 1) design with one control and four replications. The treatments consisted of four forages: Palisade grass, Congo grass, and two Guinea grass cultivars (Tanzânia and Áries); and three methods of sowing intercrops of forageautumn maize: forage sown simultaneously with maize in the sowing furrow, mixed with fertilizer; forage sown by broadcasting on the day of maize sowing; and forage seeds mixed with fertilizer broadcast on maize in growth stage V4; plus a control (maize monoculture). The decomposition and nutrient release rate of the forage residues were evaluated by the litter bag method, 30, 60, 90, and 120 days after desiccation. Sowing the forages in the furrow and by broadcasting raise the total amount of maize residues compared to method V4. Regardless of the forage type and sowing methods, intercropping increases the amount of residues compared to maize monoculture. The forages and sowing methods had no influence on nutrient accumulation in the residues at the time of desiccation and at the lowest lignin/total N ratio in Congo grass residues, and a logarithmic decay was observed. Forage and sowing methods did not influence the macronutrient release rate from crop residues for 120 days after desiccation; the release of N, P, K and Mg is logarithmic and the release of Ca and S exponential. Forage and sowing methods do not influence yield components and grain yield of subsequent soybean. However, intercropping increased grain yield of subsequent soybean compared to soybean after maize monoculture, and preserved the soil chemical and physical properties.
