5. With the increase of dose of mineral feed, all indexes of structure of above-
ground mass of plants of potato increased on all studied sorts.
6. Increase of indexes of quality (contents of starch, dry substance, and reduc-
ing sugars) at the increase of dose of fertilizers became true due to the certain
increase of level of mineral feed,
7. On reaching a certain level, there was a decline of indexes of quality. The table
of contents of nitrates in all variants did not exceed possible norms (250 mg%/
kg) maximum.
8. Nevertheless, this index rose with the increase of level of mineral feed. With
