On the experimental basis of the Chuvash Research Agricultural Institute-a branch of the Federal State Budgetary Institution “Federal Agricultural Research Center of the North-East named after N. V. Rudnitsky “, the influence of microbiological growth regulators on biometric indicators, yield and its structural elements of seed plantings of potatoes of the Chaika variety was studied. The use of leaf nutrition preparations of the agrotechnology combine “Azur-Niva LLC” contributed to: an increase in the vegetative mass of potato plants by 42 %; an increase in the yield of marketable potatoes from one bush, the number of potato tubers increased by 6.8 pcs., and the mass of tubers by 95 %; an increase in potato yield was 32.8 %.

The authors showed that the transition to the technology of virus-free minitubers mass production changed the machines requirements for planting original seed potatoes.(Research purpose) To develop a technological scheme and substantiate the design parameters of the planting apparatus of an automatic planter of potato minitubers.(Materials and methods) The development was based on an elevator-type planting apparatus. The authors decided to create a spoon design with the ability to grip and move into the guide casing one minituber in each spoon, eliminating the minitubers jumping from one spoon to another or pinching them when moving along the guiding casing to the furrow bottom. The diameters of the lower guide and upper drive rollers were theoretically substantiated in order to exclude the influence of the planting tubers sizes difference on the uniformity of their submitting into the furrow.(Results and discussion) The authors determined the minimum permissible elevator belt speed, which depended on the distance between the spoons on the elevator belt and the planting unit speed. The size of the upper driving reel diameter was justified from the condition that the spoon unfolded 180 degrees in at least 1.5 seconds, which ensured a tuber smooth transition to the back side of the spoon.(Conclusions) The authors developed a technological scheme of an automatic planting elevator type device for planting potato minitubers with a working speed of 6-9 kilometers per hour. It was found that the upper driving reel diameter was not less than 44 centimeters, and the lower guide roller diameter was not more than 12 centimeters. They showed that the double-sided design of scooping spoons with the possibility of installing replaceable bowls in them would ensure a high-quality planting of not only minitubers, but also subsequent reproductions of seed and ware potatoes with a tuber mass of 5-80 grams.

Search and introduction of new potato varieties that can be recommended for cultivation in soil and climatic conditions of the Komi Republic are especially important against the background of the average yield in the region of 12.1 t/ha, that is 6.7 t/ha lower than the average in Russia. In 2019-2020 on the basis of the A. V. Zhuravsky Institute of Agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences, there were tested potato varieties of the early maturing group – Armada, Meteor, Gulliver, Taifun and Krepysh (standard) and the mid-season group – Varyag, Vympel, Krasa Meshchery, Kumach, Fritella, Vychegodskii and Zyryanets (standard). From the early maturing group, the varieties Armada and Gulliver have been selected as giving a consistently high yield, which exceeded the standard by 6.8-7.1 t/ha on average for two years. Among mid-season varieties no one reliably exceeded the standard variety Zyryanets in terms of yield productivity. The highest yield and marketability was noted for the Fritella variety – 30.5 t/ha and 97 %. All the varieties under study, except for Vychegodskii, showed an average resistance of the tops to late blight damage. Moderate early blight damage of the tops (up to 20 % of the leaf surface) was noted in three varieties – Meteor, Taifun and Vychegodski. The following varieties showed high resistance to common scab - Vympel (no damage), Zyryanets (few lesions) and Gulliver (up to 10 % of tuber surface damage). In all studied varieties the potato tubers were not affected by late blight during both years of research. For cultivation, the agricultural producers of the Komi Republic should use the varieties Armada (29.7 t/ha), Gulliver (28.1 t/ha), Vympel (29.2 t/ha), Fritella (30.5 t/ha), which have good resistance to phytopathogens and high quality of tubers.
