“…The absence of interference by forage on corn may be due to the relatively wide distance (0.90 m) between the corn rows, which separated the forage from the corn by 0.45 m. This distance may have reduced early-season competition for water and nutrients between forage species and corn. These results are similar to those obtained by Tsumanuma (2004), who researched corn intercropped with marandu and ruzi grass, and by Borghi & Crusciol (2007), who researched corn intercropped with marandu, in São Paulo state, Brazil. Similarly, Heinrichs et al (2005) found that corn grain yield was not affected by intercropping with green manure species in the first year; in the second year, however, corn grain yield was highest when corn was intercropped with the legumes sunn hemp and pigeon pea.…”

“…The negative effect of forage plants on corn yield could result from the species or seeding rate of the intercrop (Blaser et al, 2007), or from insufficient rainfall during the late-season to support the growth of both crops (Wilkinson et al, 1987). Other researchers, however, detected no competition between corn with forage plants when forages were grown at low plant densitty in rows between corn (Tsumanuma, 2004;Freitas et al, 2005;Torres et al, 2008). The negative effects on corn caused by competition with the intercropped forage can be minimized through the use of herbicides (Freitas et al, 2005) and shading of the forage species by corn, which is enhanced by corn hybrids with expanded leaf architecture and greater leaf area (Torres et al, 2008).…”

The feasibility of no-tillage in the Cerrado (Savanna-like vegetation of Brazil) depends on the production of sufficient above-ground crop residue, which can be increased by corn-forage intercropping. This study evaluated how above-ground crop residue production and yields of soybean and late-season corn in a soybean-corn rotation were influenced by the following crops in the year before soybean: corn (Zea mays L.) intercropped with Brachiaria (Urochloa) brizantha cv. Marandu, B. decumbens cv. Basilisk, B. ruziziensis, cv. comum., Panicummaximum cv. Tanzânia, sunn hemp (Crotalaria juncea L.), pigeon pea [Cajanus cajan (L.) Millsp]; sole corn, forage sorghum [Sorghum bicolor (L.) Moench (cv. Santa Elisa)], and ruzi grass. In March 2005, corn and forage species were planted in alternate rows spaced 0.90 m apart, and sole forage species were planted in rows spaced 0.45 m apart. In October 2005, the forages were killed with glyphosate and soybean was planted. After the soybean harvest in March 2006, sole late-season corn was planted in the entire experimental area. Corn grain and stover yields were unaffected by intercropping. Above-ground crop residue was greater when corn was intercropped with Tanzania grass (10.7 Mg ha-1), Marandu (10.1 Mg ha-1), and Ruzi Grass (9.8 Mg ha-1) than when corn was not intercropped (4.0 Mg ha-1). The intercropped treatments increased the percentage of soil surface covered with crop residue. Soybean and corn grain yields were higher after sole ruzi grass and intercropped ruzi grass than after other crops. The intercropping corn with Brachiaria spp. and corn with Panicum spp. increases above-ground crop residue production and maintains nutrients in the soil without reducing late-season corn yield and the viability of no-till in the midwestern region of Brazil.

“…Similar results were found by Tsumanuma (2004) when studying the combination of three species of brachiarias (Brachiaria decumbens, Brachiaria brizantha and Brachiaria ruziziensis) being sown in two seasons (V0 and V4 stage of the maize). No statistical difference were found between treatments for the following variables: Plant height; leaf area index; diameter of the stem; leaf analysis; number of grain rows; number of grains per ear; 1000 grains weight and productivity.…”

“…Therefore, the later was the sowing of brachiaria, the lower was the production and such results corroborate Tsumanuma (2004), pointing out that late sowing affects in a bad way the initial development and the accumulation of dry matter by brachiaria, caused by water competition rate, nutrients and light, in which maize has high efficiency.…”

This study aims to determine the ideal time of green manures deployment and assess what kind of green manure will produce a favorable quantity of mass for the farming without interfering in the maize production. The experiment was conducted in Toledo -PR in 2013. It was designed in randomized blocks, in a factorial scheme (2 × 3 + 1) with 4 replications; the first factor is the species of intercropped coverage (Avena strigosa and Brachiairia ruziziensis), the second factor is the time of implementation of green manures intercropped with maize according to the phenological stages of the crop (VE, V4 and V8), and the single maize is the control treatment. The evaluated parameters were: Diameter of the stem base, ear insertion height, diameter of the base, middle and apex of the ear, ear length, number of grains per row and number of rows per ear, 1000 grain weight and productivity, and in the green manure the dry matter production. The results showed that the use of intercropping system did not affect maize yield, as well as the time of implementation of green manure. The more delayed the sowing of brachiaria, the lower its dry matter production; on the other hand oats showed opposite results, because the later its seeding is performed, the better are the results, presenting their normal development cycle. So the most feasible kind of green manure to be used according to the dry matter production is B. ruziziensis in the first sowing season (VE), being a profitable and favorable system for soil cover, without affecting maize productivity.

“…O diâmetro do colmo apresenta correlação com o rendimento, por se tratar de um órgão de reserva da planta (CRUZ et al, 2008), que serão utilizados posteriormente na formação dos grãos. Segundo Tsumanuma (2004), o diâmetro do colmo é uma estrutura destinada ao armazenamento de sólidos solúveis para situações emergenciais, e quanto maior for seu diâmetro, maior será sua capacidade de armazenamento de fotoassimilados, contribuindo consideravelmente para a formação de grãos. No trabalho, os híbridos não manifestaram indicativos que permitissem observar os melhores neste componente de produção.…”

Resumo: O estudo teve como objetivo avaliar o desempenho de híbridos simples de milho em consórcio com a forrageira (Brachiaria brizantha). O experimento foi conduzido no município de Cassilândia-MS utilizando delineamento experimental de blocos casualizados, com cinco repetições. Os tratamentos foram compostos por seis híbridos simples de milho: DKB390, BMX944, DKB399, P30F35H, P3862H e BM810. O milho foi plantado com semeadora mecanizada, no espaçamento de 0,90 m entrelinhas. A forrageira foi semeada a lanço aos 48 dias após semeadura do milho. Foram avaliados os parâmetros de componentes de produção dos híbridos de milho e da forrageira aos 117 dias após a semeadura do milho. Pelos resultados observados, o híbrido DKB399 apresentou melhor rendimento no cultivo em consórcio, sendo o mais indicado para o município de Cassilândia-MS.

The forager was seeded to haul to 48 days after sowing the corn. We evaluated the parameters of production components of hybrids of maize and beans to 117 days after sowing the corn. By the results observed, the hybrid DKB399 presented best performance in cultivation in a consortium, being the most indicated for the municipality of Cassilândia-MS.
