seedling thinning

breakthrough of seedlings, removal of extra plants from rows or nests (after bunching) to improve the growing conditions of the remaining ones. It is used on thickened crops of sugar beet, corn for grain, table and fodder root crops, sunflower and other tilled crops. It is carried out by a cultivator or thinner, which prune part of the plants in a row (mechanized thinning, or bunching), and manually (breakthrough) in the initial period of their growth and development. Plants in bouquets are sorted by hand or thinned out with harrows, followed by a check. Bouquet schemes are selected depending on the weediness of crops, the granulometric composition of the soil, and the row spacing. With the use of dotted sowing of single-seeded beets and other row crops, with intensive cultivation technology, the need for thinning seedlings is eliminated.
