The substantiation of technology and development of technical means for seeding of row crops

Abstract

Under conditions of Moldova, the SUPN-8 are the main seeders for sowing row crops. According to the experience and long-term tests of this type of seeders imported in the Republic of Moldova, the seeders do not fully meet the ATR requirements. The percentage of maize plants located at the established planting distance decreases from 45 to 34% when the speed of the seed drill increases. The second characteristic of the most seeders is the process of continuous formation of a furrow with a discrete seed laying, which requires large amounts of energy for make a sowing furrow. Improving the seeding technology and creating the seeding technique able to make the discrete sowing of the row crops at high speeds and with a high degree of planting uniformity at a given planting distance, represents an urgent task. In this context, the no till planting technology of row crops using direct planting of seeds in the holes by the rotary-type seeders is of particular interest.
