“…These differences had significant effect on the grain yield and B. brizantha straw allowed the lowest yield (3,631 kg ha -1 ) differing from the cover crops millet (4,588 kg ha -1 ) and common bean (4,979 kg ha -1 ). This could be associated with the amount of straw on the soil surface, because a large amount of straw can affect plant growth and affect yield and yield components (Monquero et al, 2010;Nascente and Crusciol, 2012;Nascente et al, 2013b). Constantin et al (2009) found that soybeans emerging on soil with a big amount of cover crop biomass had their productivity reduced.…”

“…However, to achieve better results in the NTS, proper management of the cover crop and use of herbicide are essential (Nascente et al, 2013b). The management of cover crops before planting crops is done with total systemic herbicide action, with glyphosate being the most widely used (Nascente and Crusciol, 2012;.…”

“…The right management of cover crops with chemicals can provide higher availability of nutrients due to their degradation, greater persistence of straw on the soil surface and lower release of possible allelopathic substances to the soil (Yamada and Castro, 2007;Nascente et al, 2013b). It is also very important to determine which cover crops are the best to promote higher corn and soybean productivity.…”

-To achieve better results in the no-tillage system (NTS), it is important to properly manage the cover crop prior to planting by using herbicides, usually glyphosate. The effect of glyphosate on plant coverage is slow, and plants take a few days to die completely. Thus, when applying the herbicide on the same day of planting soybean or corn, cover crops are still alive and standing, causing initial shading on seedlings of the crop and delaying its establishment. Therefore, this study aimed to evaluate the effect of distinct cover crops and their timing of desiccation prior to planting soybean or corn, on crop yield and yield components. Two experiments were installed, one for soybean and another for corn. Each experiment consisted in combining three cover crops (Brachiaria brizantha, common bean or millet) chemically desiccated at two timings before planting the crop (15 or 0 days before planting) under no-tillage system (NTS). Experiments were installed in a completely randomized block design with five replications. Brachiaria brizantha produced the highest amount of biomass; common bean and millet as cover crops allowed higher soybean grain yields; herbicide application under common bean, millet and Brachiaria brizantha 15 days before planting soybean allowed higher crop grain yields; desiccation timing of common bean did not affect corn grain yield; Brachiaria brizantha should be desiccated 15 days before planting corn to allow maximum grain yield; when millet was used as a cover crop, glyphosate application at planting of corn allowed the highest grain yield. Keywords: Brachiaria brizantha, Pennisetum glaucum, Phaseolus vulgaris, Zea mays, Glycine max, herbicidetiming. RESUMO -Para alcançar melhores resultados no sistema plantio direto (SPD), é importante o adequado manejo das plantas de cobertura com herbicida, normalmente o glifosato. O efeito do glifosato nas plantas de cobertura é lento e essas coberturas demoram alguns dias

“…Once the amounts of biomass produced by cash crops are not enough for an adequate ground cover, it is necessary to introduce cover crops to produce the required volume of biomass in the off-season Nascente et al, 2013c). Then, soil will remain covered as long as possible until the following summer crop (Nascente et al, 2012b).…”

“…It may happen because the systemic characteristic of glyphosate, the principal herbicide used in chemical management of cover crops, which take some days to dry completely the crops (Franz, 1985). Therefore, at the cash crop sowing day cover crops are not completely dry and with high amount of biomass it can cause difficulties to cut their leaves by the discs of the planter (Grisso et al, 2002;Nascente et al, 2013c). In addition, other factors such as an initial shading in the crops, possible translocation of herbicide from target plants (cover crops) to non-target plants (cash crops), increasing demand for nitrogen by decomposing microorganisms, allelopathic effects and other aspects still must be studied, understood and avoided (Weston, 1990;Miyazawa et al, 2002;Barbosa et al, 2008;Nascente et al, 2012a).…”

A B S T R A C TAn important point in no-tillage system is the time between cover crop glyphosate desiccation and rice sowing. This study aimed to verify the effect of Brachiaria ruziziensis management time before rice sowing on rice yield and its components. The experiment was conducted under greenhouse conditions and consisted of four types of B. ruziziensis management: with Brachiaria and with herbicide (WBWH), without Brachiaria shoots and with herbicide (NBWH), without Brachiaria shoots and without herbicide (NBNH), and with Brachiaria and without herbicide (WBNH), at four times: 30, 20, 10, and 0 days, preceding the rice sowing. The amount of B. ruziziensis dry matter increased as the management was done closer to the rice sowing date. The WBWH and WBNH managements (this one causes the lowest rice grain yield) must be done 30 days before rice sowing; while NBWH management must be done ten or more days before rice sowing. On the other hand, NBNH management (this one favors the best rice grain yield) can be done until rice sowing day. Despite some reduction in rice yield caused by the B. ruziziensis management, when it was done at the proper time the rice grain yield was similar to the control (without Brachiaria sowing and without herbicide application).Produtividade do arroz de terras altas em função do manejo da cobertura de Brachiaria R E S U M ONo sistema de plantio direto é importante o tempo entre a dessecação da cobertura com glifosato e a semeadura do arroz. Este estudo objetivou verificar o efeito da época de manejo da Brachiaria ruziziensis antes da semeadura do arroz na produtividade do arroz e seus componentes de produção. O experimento foi conduzido em casa de vegetação, com quatro tipos de manejo da B. ruziziensis: com Brachiaria e com herbicida (CBCH), sem a parte aérea da Brachiaria e com herbicida (SBCH), com Brachiaria e sem herbicida (CBSH) e sem a parte aérea da Brachiaria e sem herbicida (SBSH), em quatro épocas: 30, 20, 10 e 0 dias anteriores à semeadura do arroz. A matéria seca de B. ruziziensis aumentou à medida que o manejo foi realizado próximo à semeadura do arroz. Os manejos CBCH e CBSH (este proporcionou a menor produtividade de arroz) devem ser feitos 30 dias antes da semeadura do arroz; já o manejo SBCH deve ser feito dez ou mais dias antes da semeadura. O manejo SBSH, que proporcionou a maior produtividade de arroz, pode ser feito até o dia da semeadura do arroz. Apesar de alguma redução na produtividade causada pelo manejo da B. ruziziensis, quando ele foi feito no momento adequado a produtividade do arroz foi semelhante ao controle (sem semeadura da Brachiaria e sem herbicida).
