Determination of the distance between dots at band scheme of sowing onion seeds
The article presents the results of field tests of an experimental seeder when sowing seeds of onion varieties “Bereketli” with a ribbon-dotted pattern. At the same time, the developed technological scheme and the principle of operation of the experimental machine are presented. The experimental machine is based on the SZS-2,1 seeder with a reel-to-reel sowing device. The experimental seeder is additionally equipped with Romanian-made “HRC” seed drills.Processing the results of experiments of mathematical statistics show that with an increase in the speed of the tractor movement, the coefficient of variation, the arithmetic mean and root-mean-square value increases.
