Conteúdo: | The purpose of this research was to assess the crop rotation affectson agronomic traits of soybean in optimal (OCS)and dry cropping seasons(DCS). This research was carried out in 2010/2011(OCS)and 2011/2012 (DCS)in a Rhodic Hapludoxsoil. The experimental design was set up in a randomized complete block and the treatments were arranged in a factorial 9 x 2, consisting of 9 crop rotations systems and two cropping seasons, with four replications. The soybean (Glycine maxcv. BMX -Potência RR) was sowed on October 20 th 2010 and October 10th 2011(spring- summer season) 20 days after the fall - winter cover crops desiccation . It was assessed in the R8 reproductive stage (Full maturation) the plant height, the height of the first pod insertion , number of pod per plants, number of branches per plant, number of seed per pod, 1000 - grain weight and grain yield. I t was observed that in drought stress (DCS), the number of branches decrease d, this reduction was 36% in relation to OCS. For the traits as plant height, first podheight, 1000 - grain weight and yield, it was showed small values in DCS in contrast to OCS. It is feasible to introduce these cover crops in fall -winter season to make part of a crop rotation system. The number of pod per plant showed higher values under the crop rotation of corn/rapeseed/soybean, which showed highly associated with the soybean grain yield. This research brought options for cover crops system to be viable in no - till system with soybean in spring-summer season.
