The effect of microfertilizer «Agro-Master» on the yield and quality of early and medium early of potato tubers varieties was studied, carried out at the experimental field of North Caucasus Research Institute of Mountain and Foothill Agriculture - branch of the VSC of RAS in the forest-steppe zone of Republic of North Ossetia-Alania on grass rotation in the period from 2017 to 2019 yy. The experimental data indicate that the use of microfertilizer «Agro-Master» in a specific soil and climate zone is a promising technique that can improve the productivity and quality of potato tubers in the field. The data of our studies on leached chernozems showed no clear differences in the timing of the onset of the development phases of potatoes. The intensity and speed of emergence of seedlings to a greater extent depends on weather conditions and varietal characteristics. It was found that when spraying potatoes with microfertilizer «Agro-Master» in different doses, the process of dying of tops is slowed down in comparison with the control options. So, in the Zukofsky early variety, the top-off phase begins 7-8 days earlier than the Red Scarlett variety and 10-11 days of the Predgorny variety of local selection. The maximum yield increase was observed when processing of the microfertilizer «Agro-Master» at a dose of 2 kg/he on the pre-mountain local breeding grade – 27,5 tons per hectare, while the increase in yield to control was 5,0 tons per hectare, for varieties of Zukofsky early and Red Scarlett – 5,0 and 4,7 tons per hectare respectively. The highest dry matter content was on the experimental version (dose 2 kg / ha) for the Predgorny variety – 26,6 %, the Zukofsky early and Red Scarlett varieties – 25,9 and 23,8 %, that accordingly is more than control on 3; 2 and 3 %. The starch content in the studied potato tubers in the experimental varieties was diverse. The maximum starch content in potato tubers was obtained using the variant treated with Agro-Master at a dose of 2 kg/he for Predgorny variety (16,0 %), which is explained by the favorable influence of microfertilizer «Agro-Master» and the manifestation of varietal characteristics.

Increasing concerns have been verified with regard to the quality factor of potato tubers and their correct form of use and consumption. The purpose of this research was to determine the technological quality of potato tuber cultivars and identify the best forms of use and consumption. A completely randomized experimental design was adopted with 18 treatments represented by cultivars Agata, Apuã (IAC-5977), Aracy (IAC-2), IAC Aracy Ruiva, Asterix, Bintje, Dali, Clone IAC-6090, Itararé (IAC-5986), Laguna, Remarka, Liseta, Mondial, Novita, Oscar, Picasso, Santana, and Solide, with four replications. Specific gravity showed a positive correlation with starch content, texture, pulp pH, and soluble solids, and was negatively correlated with reducing sugars. The technological characteristics represented by specific gravity, dry matter content, texture, starch content, reducing sugars, pulp pH, titrable acidity, and soluble solids are influenced by genotype or cultivar. Cultivars Oscar, Itararé, IAC Aracy Ruiva, Clone IAC-6090, Aracy, Solide, Asterix, Santana, and Laguna were outstanding with best characteristics for frying, mashing and roasting. Mondial, Picasso, Novita, Dali, and Agata are appropriate for boiling, and more specifically for salads. In turn, potato cultivars Apuã, Remarka, Bintje, and Liseta are suitable for mashing and for roasting.

In 2014-2017  In the northern forest-steppe zone of the Chelyabinsk region The influence of planting dates and the depth of seed placement of potatoes on the size and quality of tubers was studied. During the study period, physical soil maturity in the first decade of May was observed twice in 2014 and 2017. The early planting of potatoes (May 5) was accompanied by an increase in the harmfulness of rhizoctoniosis (in the Rosara variety - by 22.8%, Kuzovok - by 63.7%) and the Colorado potato beetle (by 26 and 43%, respectively) compared with the May 12-15 planting. . The seedlings of the early variety of Rosara potato on May 30 in 2014 were damaged by frost (–1.0 ° C). From meteorological and phytosanitary positions, the optimum term for planting potatoes in this is the beginning of the second decade of May. Planting potatoes on May 12-15 with embedding of seed material to a depth of 5-6 cm ensured the formation of the planned yield of 40 t / ha with a planting scheme of 70x19 cm (Rosara - 41.4 t / ha, Kuzovok - 44.6 t / ha), and in the variety Kuzovok - additionally with the scheme 75x27 cm (38.3 t / ha). The planting of potatoes on May 25-29 provided a predetermined level of productivity (40 t / ha) of the Kuzovok variety in all variants of the experiment, and the Rosara variety in the variant of thickened planting. However, the starch content in Rosara tubers decreased by 1.60%, Kuzovok - by 1.26%, starch collection from 1 ha decreased by 0.60 and 0.37 t / ha, respectively, and the accumulation of nitrates in tubers increased by 25.8 and 52.5% compared with the optimal landing period. The advantage here was a deep embedment of seed tubers: an increase in the yield of the Rosara variety averaged 0.88 t / ha, Kuzovok - 1.23 t / ha. During the late planting period (June 5–12), there was a significant decrease in productivity (Rosara - by 3.49 t / ha, Kuzovok - by 5.18 t / ha) and the quality of potato tubers compared to planting from May 12-15. The starchy content of tubers decreased by 1.87 and 2.11%, the collection of starch from 1 ha to 1.10 and 1.45 t / ha, respectively, and the accumulation of nitrates increased 2.05 and 2.19 times. The planned yield of 40 t / ha was achieved only in the variety Kuzovok in thickened planting variants. At the same time, deep seeding of seed material increased the yield of the Rosara variety on average by 1.39 t / ha, and the Kuzovok variety - by 1.90 t / ha. Early landing (May 5) in 2014 and 2017. did not lead to an increase in potato productivity compared to planting in the second decade of May. At the same time, the yield decrease of the Rosara variety was 5.82 t / ha, Kuzovok - 2.75 t / ha. The planned yield of 40 t / ha was noted only in the variant of the thickened planting of the variety Kuzovok.

An application of calculated doses of fertilizer for potatoes in the gray forest soil of medium-size distribution, on average for 4 years, provided a receipt of planned crop of 25-35 tons per hectare and 94% of planned harvest in the background of 40 tons of tubers per hectare. Thus at higher fertilizer backgrounds, calculated to harvest 35-40 tons tubers per hectare, the starch content decreased and its harvest increased 2.22-2.33 times. The maximum permissible concentration of nitrate in potato tubers does not exceed.

The most significant in the technology of growing potatoes are the timing of removal of the tops, as this factor directly affects the physiological state of the tubers and their quality. Therefore, the aim of the study was to determine the effect of the timing of removal of tops on yield, quantitative yield and quality of elite seed of early maturing potato varieties Snegir, Delphin, Udacha and Zhukovskij rannij. Experience, observations and accounting were carried out according to generally accepted methods. The study was conducted in a field experiment of the Smolensk Institute of agriculture (ex. Smolensk GOSHOS). As a result of phenological observations, it was found that the mass flowering did not occur simultaneously in all studied potato varieties. Before all the phase of mass flowering occurred in the Zhukovskij rannij variety. The percentage of plant viral diseases in all studied varieties in the variant with the term of removal of the tops 21 days after mass flowering was higher, compared with the options for removing the tops in earlier flowering periods. The maximum yield of seed fraction of potato tubers in varieties Delphin and Snegir (12.6 and 26.1 t/ha, respectively) was noted in the version with the second term of removal of the tops, in varieties Zhukovskij rannij and Udacha (23.2 and 23.4 t/ha, respectively) – in the version with the term of removal of the tops 21 days after mass flowering. The yield of tubers seed fraction and their mass were the highest varieties of Dеlphin and Zhukovskij rannij. According to the results of the tuberous analysis, an increase in the total number of tubers affected by fungal diseases was observed in variants with later dates of removal of the tops. The most affected disease of all the studied varieties was the grade of bullfinch (1.5-4%), the most resistant to disease – cv. Udacha.
