Structural layouts of coulters and their groups in potato planters are justified in the article based on the morphological features of the potato plant, its requirements for growing conditions and ensuring the quality of the planting process. The purpose of coulter groups is to form a bed for placing tubers with a loose layer of soil in 5-8 cm and sealing them with loosened soil to a certain depth. To substantiate the type of potato planter coulters that meet the requirements for potato growing conditions to the maximum extent possible, optimize the parameters of coulter groups that automatically ensure the stability of the coulter travel depth when imitating irregularities of the field microrelief. A comparative analysis of the impact on the soil of the most common anchor coulters with a blunt angle of soil entry and a sharp angle with an individual floating suspension is given, and indicators of the quality of their operation are described. It was found that coulters with an individual floating suspension and an acute angle of soil entry meet the requirements for potato growing conditions to the maximum extent possible. In order to ensure travel stabilization of such a coulter at a given depth when imitating field irregularities, a version of the coulter group has been developed that provides automatic correction of the coulter's angle of attack when changing its travel depth. Experimental studies have optimized the parameters of the coulter suspension that ensure automatic imitation of field microrelief irregularities up to 20 cm deep within the initial requirements for potato planting machines. Coulters with an individual floating suspension and a sharp angle of soil entry most fully meet the requirements for potato growing conditions to the maximum extent possible. A coulter group with a suspension aspect ratio of 150:200:400:400 cm and an acute angle of coulter entry into the soil provides automatic maintenance of the set coulter travel depth within the initial requirements (±2 cm) for irregularities in the field microrelief of up to 200 mm. In this case, the bottom and walls of the furrow are not compacted.

The paper presents data on the biotechnology of growing accumulative cultures of algae Scenedesmus quadricauda when adding organo-mineral complex drag to the culture growth medium. It is shown that the trace elements that make up the drug (trade name “Helavit”), at the studied concentrations, act in various ways stimulating and inhibiting the growth of algological culture. Having a different effect in the concentration range from 0.1 to 1 mg / L. The maximum positive effect is achieved with a drug concentration of 0.3 mg / l (8986 ± 120 103*cells/ ml), which can be recommended for mass cultivation of algae. A possible cause of inhibition of culture growth, at a concentration of 0.1 mg / l (6960 ± 115 103*cells/ ml), are the inhibitory effects of copper and iodine ions.

The purpose of this study is to substantiate the concept of a device for the evaluation of the suitability of varieties and hybrids of potato tubers for mechanical harvesting from the earliest stages of the selection process and to perform quantitative and structural assessment of damage to potato varieties and hybrids inflicted by the device, simulating the process of the harvester’s separating element operation depending on the machine type and harvesting conditions. The structural and operating diagram of the device for the evaluation of suitability of varieties and hybrids for mechanized harvesting has been developed, and the procedure and results of the study to determine the force action of the separating surface of the developed device on the potato tubers are presented. The device developed in accordance with the proposed conceptual scheme, further calibrated to account for modern potato harvesters would make it possible to conduct targeted selection of varieties suitable for mechanized cultivation, as well as to assess the degree of resistance of potato varieties to mechanized harvesting at early stages of selective and seed production works.

The article deals with topical issues of high-tech production development of minced meat semi-finished products with added benefits as an imperative of new industrialization. The use and processing of agricultural grain raw materials in the Sverdlovsk region will allow local enterprises of the agro-industrial complex to develop steadily and strengthen ties with potential consumers of processed grain raw materials. Creating innovative food products for mass consumption is one of the main tasks of the state policy in the field of healthy nutrition of the population. Research on the development of minced meat semi-finished products with the addition of food grain matrix is presented. An increase in the nutritional, biological and physiological value for the human body, the prospects of using grain matrix in the technology of production of minced meat products from poultry (turkey) have been established. The development of innovative food products is one of the priority areas for the development of the consumer market.
