SEMEADURA DA SOJA EM DIFERENTES SISTEMAS DE PREPARO DE SOLO

Abstract

Crops of great global importance, such as soybean (Glycine max), are derived from the sowing process. This step in the production cycle can be considered the most important, because as it is carried out, the deposition of the seed in the soil will directly impact the final productivity. Thus, it must be carried out assertively, in order to guarantee a better uniformity of seed distribution. This study aimed to evaluate the interference of operating speed and different furrow closing pressures on the longitudinal distribution of seeds, productivity, soil mobilization and sowing depth in the two planting systems used. The experimental units of the treatments had an area of 10 m². A randomized block design (DBC) was carried out in a 2x2x3 factorial system with four replications, with 2 types of soil preparation, 2 operating speeds and 3 pressures in the furrow closing system.
