Performance of pneumatic and mechanical seeder-fertilizer at different speeds in soybean

, 2020
Sowing is an operation that interferes with the development of soybean plants and, consequently, yield crop, which both seed distribution mechanisms and sowing speed can impair the success of the crop. In this context, the objective of this study was to evaluate the interference of mechanical and pneumatic distribution of seeds at different speeds both
