Movement of seeds in the underweep space of drill coulter in the condition of pneumatic feed

Abstract

The analysis of various methods of sowing of grain crops showed that the introduction of indirect sowing in agricultural production contributes to the increase in their productivity. The authors propose justified structural and technological scheme of the sowing system in order to ensure a uniform distribution of seeds over the feeding area to a given depth with their subsequent seeding. The main element of the sowing system is the pneumatic seed feed. Due to the movement in the airflow, the seeds of grain crops at the moment of the concussion against the surface of the distributor have sufficient speed to reach any point on the surface under a V-shaped weep; this contributes to the uniform distribution of seeds across the entire width of the sowing strip.

Double Disc Colter for a Zero-Till Seeder Simultaneously Applying Granular Fertilizers and Wheat Seeds

“…However, the optimal seeding rate should be determined to avoid competition between seeds. Applying the wheat seeds to the horizontal band with the granular fertilizer in a narrow band is implemented in traditional tillage systems but not zero-till systems [36]. Considering the abovementioned issues, the research aimed to design a new double disc colter applying the wheat seeds to the horizontal band with the granular fertilizer in a narrow band below the seed in a zero-till system.…”
