| Popis: | The soybean, the main crop in the state of Tocantins, responds differentially to environment for the agronomic characteristics, so that regionalized trials seasons planting should be performed. In this sense, considering the importance of season planting and the scarcity of studies for the soybean crop in the State of Tocantins, eight competition trials were performed, being four in the 2014/15 harvest and four in the 2015/16 harvest in Porto Nacional and Santa Rosa - TO. The experimental design used in each trial was a randomized block with three replications and seven treatments (cultivars). The characteristics evaluated were: days until flowering and maturation, plant height, height of 1st pod, number of seeds per pod, number of pods / plant, weight of thousand kernels (g) and grain yield (kg ha-1). In Porto Nacional, there was the highest yield in both seasons. The later sowing resulted in a drop in yield potential of cultivars. The cultivar 8579RSF IPRO showed better performance in both places and times. |
