This study discusses a plant breeding and seed system recovery. According to the 2013 information, over 3000 seeders with colters of strip cropping were upgraded, which worked in 64 regions of the country. Simultaneously with the work on the modernization of the seeders for strip cropping, Russian Institute of Mechanization together with LLC “Tekhtsentr Laishevo” and “KhaRaSha” developed a design specification on the universal seeder SUZT 4of strip cropping with 4 meter width and a design specification on unified with it breeding and farming seeder SFS -2 with 2 meter wide. The pilot seeder SUZT-4 was designrd in LLC “KhaRaSha” and in 2012 it was successfully held acceptance tests with the recommendation on production at the Kirov Machine Testing Station. This seeder is designed for strip sowing of cereals, legumes, small-seeded crops and grass with simultaneous application of mineral fertilizers, as well as for early spring narrowband sowing of sparse winter crops and perennial grasses and subsurface mineral fertilizers plant nutrition. In 2013 there have manufactured a pilotmachine of breeding and farming seeder SFS-2 and it was transferred to Machine Testing Station for carrying out acceptance tests. The speeding up the implementing these seeders allow to carry out technological operation of planting crops in a highly effective stripping way with a significant increase of productivity and with high quality seeds. On spring wheat crops, where the seeds were prepared by car SMVO and sowing performed by seeders with ODA colters of strip cropping, the field germination ranged was from 92.5 to 95.6%, which is 4.5-8.1% higher, than seeds, obtained without isolation of their specific weight and drill sowing by double disc coulters. As a result, the higher harvest is formed by 8-10 centner per hectare and more. Additional 1.0 million tons of crops were reaped from improved seeds quality. Thus, the use of universal seeders with single disc - hoe colters and seed-crop cleaning machines SMVO is the most affordable way to increase the crops yield and seed quality for all farms. Key words: selection and seed-farming, Seed-growers association, seed-crop cleaning machine, processing of grain and seed, a seeder with disc-hoe colters, strip cropping .

Abstract. The article presents the results of R&D and new units for the restoration of degraded mountain areas. The purpose of the study is the accelerated restoration of the natural phytocenosis and the implementation of measures to improve meadows using these aggregates. The object of the study is the technologies and units developed by the authors for the following operations: cutting bumps, raking stones, sowing grass mixtures with the simultaneous application of mineral fertilizers. The research objectives included: determining the initial floristic composition of a degraded mountain meadow; assessment of the impact of events and agricultural practices on the change in the floristic composition of the grass stand, its productivity and energy intensity; identification of the effectiveness of the application of the developed units when sowing herbs in turf and targeted application of mineral fertilizers. The novelty of the technical solution lies in the fact that new resource-saving methods have been developed to improve mountain fodder land using small-sized universal units. . The tests were carried out at a mountain hospital located on the southeastern exposition of the Dargavskiy depression of the North Ossetia-Alania, at an altitude of 1650 m above sea level with a slope of 10°, in six plots, with a recorded area of 360 m2. Three options in triplicate. The first option is natural seeding, and the second is grass seeding by the aggregate, the third option is grass seeding and low doses of N60P45K20 fertilizers. The plots are located across the slope randomized. It was found that at a concentration of 17.2 MJ of energy in 1 kg of dry matter of feed, the total collection in the control plot was 29.7 GJ, and in the seeded experimental field – 85.3 GJ; the crop of the aboveground fodder mass, when sowing grasses, in the first year of observations amounted to 21.8 c/ha of dry weight, which is 3 times higher than in the control. During the growing season of the third year of observations, the yield in the sown area was 39.2 c/ha of dry weight against 19.3 c/ha in the control.

To reduce the accumulation of toxic substances in tubers in 2014–2016 the author studied biological methods of fertilizers application and plant protection in black earth forest-steppe region under the conditions of high-intensity potato cultivation technology along with drip irrigation. The introduction describes the importance of potato in the diet of population and lists the environmental issues that arise as a result of enhanced using of chemicals during crop cultivation. The doses of mineral fertilizers in experiments were introduced separately and in combination with a bioameliorant: 1) without fertilizers (control site); 2) N60P90K60; 3) N90P135K90; 4) N120P180K120; 5) biological ameliorant – white mustard, post-harvest green manure; 6) bioameliorant + N60P90K60; 7) bioameliorant + N90P135K90; 8) bioameliorant + N120P180K120. Chemical insecticide Aktara and biological preparations Fitoverm, Akarin were used to protect potatoes against Colorado potato beetles. Insecto-fungicide Celest was used to treat seed tubers against fungal diseases. During growing season the author used fungicides Profit Gold, Ridomil Gold against fungal diseases, against weeds – Zenkor and Remus. High yield of potato environmentally friendly considering nitrates was obtained by means of simultaneous application of N90P135K90 and white mustard green mass. Tuber yield was 40.4 tonnes per hectare compared to 22.7 tonnes per hectare on the control site, and nitrate content was 111.3 mg while maximum permissible concentration (MPC) is 250 mg/kg. According to MPC established in the Russian Federation, for childrenʼs and dietary nutrition fertilizer dose should not exceed N60P90K60 in combination with a bioameliorant and a biological plant protection system. Safety interval (period between plant treatment and harvesting) for chemical insecticides is 35–40 days; fungicides – 20 days; herbicides (depending on their type) – 55–70 days. The production of ecologically clean potato according to EU standards was achieved only by means of using post-harvest green manure as a fertilizer, applying biological insecticides and Celest preparation within the framework of protecting plants against pests and diseases.

Abstract. The authors presented the results of scientific research and experimental development, on the basis of which a prototype was designed and created for applying liquid fertilizers to the grass and the soil surface of mountain meadows and pastures in order to improve them, reduce erosion processes and increase productivity. The aim of the work: to develop and create a combined multifunctional unit for the application of liquid fertilizers on mountain meadows and pastures, providing an increase in the productivity of agricultural landscapes and profitability of agricultural production by 15–20 %. The object of the study are fertilizer application rates and interchangeable working parts: a container for liquid mineral fertilizers, a collector of sprayers, tips. The novelty of the technical solution lies in the fact that a combined multifunctional unit based on a chisel cultivator ССМ-2,4 was created for the first time. The research of the unit was carried out on the basis of the workshop of the mechanization group of the North Caucasus Research Institute of Mining and Piedmont Agriculture (NCRIMPAC) and at the high-altitude experimental site in the village of Dargavs Prigorodny district of North Ossetia-Alania. When creating a prototype of a unit for applying liquid fertilizers, the developments of the authors are used and combined, which are confirmed by the issuance of patents for useful model of the Russian Federation No. 144420 and No. 130781. As a result of the application of the developed prototype of the unit, the erosion processes are reduced, the productivity and profitability of the sloping lands increases, and the botanical composition of the herbs is improved. It was established that the design and functionality of the proposed unit also allow it to be used in the mountain zone in nursery farms and on tilled crops with simultaneous application of liquid fertilizers in the forest zone. The use of a prototype unit will reduce erosion and other types of degradation of the fertile soil in the mountains, solve the problem of surface improvement of hayfields and pastures and, as a result, increase the productivity of forage lands by 15–20 %.

Abstract. Low-density lipoprotein cholesterol (LDL-C) has been proven to be a causal factor of atherosclerosis and, along with other triggers like inflammation, the most frequent reason for peripheral arterial disease. Moreover, a linear correlation between LDL-C concentration and cardiovascular outcome in high-risk patients could be established during the past century. After the development of statins, numerous randomized trials have shown the superiority for LDL-C reduction and hence the decrease in cardiovascular outcomes including mortality. Over the past decades it became evident that more intense LDL-C lowering, by either the use of highly potent statin supplements or by additional cholesterol absorption inhibitor application, accounted for an even more profound cardiovascular risk reduction. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a serin protease with effect on the LDL receptor cycle leading to its degradation and therefore preventing continuing LDL-C clearance from the blood, is the target of a newly developed monoclonal antibody facilitating astounding LDL-C reduction far below to what has been set as target level by recent ESC/EAS guidelines in management of dyslipidaemias. Large randomized outcome trials including subjects with PAD so far have been able to prove significant and even more intense cardiovascular risk reduction via further LDL-C debasement on top of high-intensity statin medication. Another approach for LDL-C reduction is a silencing interfering RNA muting the translation of PCSK9 intracellularly. Moreover, PCSK9 concentrations are elevated in cells involved in plaque composition, so the potency of intracellular PCSK9 inhibition and therefore prevention or reversal of plaques may provide this mechanism of action on PCSK9 with additional beneficial effects on cells involved in plaque formation. Thus, simultaneous application of statins and PCSK9 inhibitors promise to reduce cardiovascular event burden by both LDL-C reduction and pleiotropic effects of both agents.
