Abstract: Objetivou-se com este trabalho avaliar a formação de cobertura vegetal por Brachiaria brizantha e B. decumbens, bem como as interações entre as coberturas vegetais, as dosagens do herbicida glifosato e a aplicação da mistura fluazifop-p-butil + fomesafen, no manejo das plantas daninhas e na produção da soja MG/BR 46 - Conquista em sistema plantio direto. Utilizou-se delineamento experimental de blocos ao acaso, num esquema de parcelas subsubdivididas, com quatro repetições. Testaram-se duas espécies de braquiá… Show more

“…In a study by Nunes et al (2010), at the time of sowing the soybean the amount of straw from Brachiaria brizantha and Brachiaria decumbens was respectively 8, 700 and 11,200 kg ha -1 ; values which had no significant effect on the height of the soybean plants, corroborating with the present study. Flores et al (2007) also found no significant difference in soybean yield at grazing heights which were the same as in this work (10, 20, 30 and 40 cm) or in an area with no grazing (NG).…”

“…Pacheco et al (2011) however, working with cover plants in winter for two consecutive seasons, observed 120 days after dessication, a remaining 1,172 kg ha -1 preceding the first crop and 3,900 kg ha -1 preceding the second, corresponding to 18.8% and 51.6% of the initial dry matter of Brachiaria ruziziensis respectively. Nunes et al (2010) found at 135 days after sowing, and at the end of the soybean cycle, an amount of dry matter of 5,700 and 7,200 kg ha -1 for B. brizantha and B. decumbens respectively, leaving an evident and adequate cover during the soybean cycle.…”

“…Em relação à altura de inserção da primeira vagem, altura de plantas, estande final m -1 , número de vagens e massa de cem grãos da cultura da soja, os diferentes gastos de sementes das diferentes coberturas e o tratamento padrão, não propiciaram diferenças significativas, em nível de 5% de probabilidade pelo teste de Tukey, no entanto, os valores da massa de cem grãos foram superiores aos encontrados por Nunes et al (2010) Muraishi et al (2005) verificaram diferenças com relação a altura de plantas e massa de mil grãos da cultura da soja.…”

“…que a torna recomendável para quase todos os estados brasileiros, em razão da sua alta adaptabilidade. Essa cultivar é bastante cultivada e estudada na região de Jaboticabal (Beutler et al, 2007;Nunes et al, 2010). As parcelas foram constituídas por cinco linhas de 3 m de comprimento, com espaçamento de 0,45 m, o que resultou em área total de 6,75 m 2 .…”

“…Among the beneficial factors of this accumulation and retention of biomass in the soil are: increased moisture retention, greater control of soil temperature range (Torres et al, 2006), control weeds, and (Nunes et al, 2010) the release of nutrients to the decomposition of biomass for soybeans also providing for greater productivity (Boer et al, 2008). Lemos et al (2003) observed that the largest soybean production occurred in conditions of greater production of biomass.…”
