The number of mini-tubers of potatoes depending on the density of planting micro-plants

Abstract

Abstract The obtained results indicate the influence of the feeding area of potato micro-plants on the number of mini-tubers of promising varieties. In the experiments, micro-plants were placed in pots as follows: one plant in a pot with a nutritional area of 380 cm2, two plants in a pot - 190 cm2, three plants - 127 cm2, plants - 95 cm2. It was noted that with a decrease in the area of plant nutrition, the height of plants increased, as well as the number of tubers obtained from one plant. The study of the fractional composition of tubers showed that in order to obtain the maximum number of mini-tubers of potatoes, the most valuable fraction for further planting is not recommended to place one plant in a pot. Varieties reacted differently to the density of micro-plantings. For example, Gulliver and meteor varieties have an optimal feeding area for one plant to form tubers of the optimal fraction of 190 cm2, Zumba and Samba – 127 cm2, Reggae and Courtney – 95 cm2. In the salsa variety, there were no differences in this trait between variants with a feeding area of 95 to 190 cm2.
