| Sumario: | In crop-livestock system in Southern Brazil is usual the common bean, soybean and corn cropping after annual
winter pasture. The objective of this work was to evaluate the effect of time intervals between ryegrass desiccation and the
common bean, soybean and corn sowing on crop performance, in no-tillage system. Three experiments were carried out in
Major Vieira, Santa Catarina, Southern Brazil, in 2009/10 crop season. The experimental design was a completely
randomized, with three replications. Were evaluated four time intervals between ryegrass desiccation and sowing crops: 0, 10,
22 and 31 days. Ryegrass desiccation near the common bean, soybean and corn sowing showed higher straw production and
straw cover at sowing, but decreased the soil cover by crops plants in the beginning of their cycle. However, the grain yields
and its components (number of plants per area, number of pods/ears per plant, number of grains per pod/ear and grains
mass) were not affected by time intervals between ryegrass desiccation and crops sowing. |
