KARINE DE LIMA SILVA, Yara et al. Soil tillage systems and their effects on soybean crop development. Investig. Agrar. [online]. 2021, vol.23, n.2, pp.94-100. ISSN 2305-0683.  https://doi.org/10.18004/investig.agrar.2021.diciembre.2302672.

Soil tillage systems can influence crop development. In order to evaluate the effects of tillage equipment on soil physics and soybean development, five soil tillage systems were evaluated (mouldboard plow, disc plow, intermediate harrow, scarifier and rotary hoe) and their effect on aggregates of a dystrophic Red Yellow Latosol. A completely randomized design with four replications was used. The tillage systems influenced the average height of the plants in the soybean crop. Soil preparation with disc plows and moldboards cause larger plant sizes compared to the scarifier. Periodic soil tillage systems do not influence the development and productivity of the soybean crop.

Keywords : agronomic attributes; conventional tillage; primary periodic soil preparation.
