Abstract

One of the factors of low productivity is the difficulty of establishing the ideal population of plants at sowing time, due to the several factors that prevent the normal germination of part of the seeds. Among the primordial factors for germination are humidity, temperature, and airing of the soil. It is important to mention that these factors are directly influenced by the state of soil compaction around the seed. The present work aimed to study the effects of the combination between depths of sowing and loads applied by press wheel of the seeder on the emergence and development of bean culture, in no-tillage systems. The factorial scheme was applied, at the delineation in random blocks composed of twelve treatments (three depths of sowing and four levels of loads applied by the press wheel) and four replications. The results showed that the sowing performed at 5.0 cm of depth presented the best index of speed emergence when compared to the depths of 3.0 and 7.0 cm.
