The object of research in this article is the design of the filter with bulk dispersed media; this type of device has a wide application within the framework of water treatment for technological needs of food enterprises. On the basis of the data of the previously obtained complex of theoretical and experimental studies of the process of bulk filtration of mechanically activated aqueous solutions, the main purpose of the work is to find effective options for modernisation of the filter design with bulk dispersed media, allowing one to improve the filtration process, namely to increase productivity and improve the quality of filtrate. The research methods included both theoretical (methods of analysis, comparison, etc.) and experimental measures aimed at studying vibromechanical activation of the initial solution in the process of filtration, studying the physical and chemical properties of the activated solution, and determining the rational modes of mechanical action. The results obtained in the course of the research are determined by the basis of the modernisation of the device, the changes made in the design had a positive effect on its operation, and the cycle time changed by 20-22 %. The achievements of the device modernisation are represented by: built-in vibromechanoactivators; washing and regeneration without the use of reagents; measurement by sensors of indicators in the device tanks before and after the filtering process; improved wear resistance and durability of the casing coating inside and outside. On this basis, further plans are focused on the realisation of the design ideas into an experimental industrial unit and subsequent research in laboratory and industrial conditions.

There is still no consensus on the composition of nutrient media for various genotypes, and the improvement of their composition is still an urgent problem, the solution of which can significantly speed up and facilitate the breeding process, both in traditional and heterotic breeding. In this regard, the main goal of the study was to compile new variants of nutrient media and establish the relationship between changes in the components of the medium and the efficiency of callus formation. Previously, we showed the advantage of the RZ nutrient medium (Raina, Zapata. 1997) over the N nutrient medium (Nitsch, Nitsch 1969) for domestic varieties and hybrids, but to further increase the efficiency of callusogenesis, 5 variants based on the RZ nutrient medium were developed. The nutrient medium R1 was characterized by a reduced content of CaCl2·2H2O by almost three times, however, the results obtained on it were significantly better than on the initial nutrient medium RZ.

This article is intended to substantiate the role of innovations in the development of agriculture in Russia. The authors of the article focused on identifying the importance of innovative techniques and technologies in the modern development of the agricultural industry. The current directions of innovative developments in the agricultural sector in Russia have been identified and investigated. The conditions for achieving effective implementation of digital land use projects are presented; “Smart field”; “Smart garden; Smart farm. The experience and level of development of innovative techniques and technologies in foreign countries are considered. An up-to-date list of both Russian and foreign manufacturers of innovative developments, the buyers of which are domestic agricultural organizations, is presented. The factors that hinder the active implementation of innovations in the activities of agricultural entities in Russia have been identified. A diagram of the relationship between the components of the process of creating and applying innovative technologies has been developed. Also the author’s schematic position of the role and place of innovations in the process of creating and applying innovative technologies is presented. As a result of the research, there were given recommendations for eliminating the identified problems in the field of introducing innovative techniques and technologies in agricultural production.

The paper describes a method for creating new and increasing the yield of existing varieties based on analysis variability elements of rice varieties yield structure under influence of environmental conditions. Seeding rates are used as a source of variability. Following trait are analyzed: seeds field germination, survival plants before harvesting, total tillering of plants, realization of total tillering, graininess of panicle, fertility of spikelets, weight of 1000 grains. Based on analysis, through onnections conjugated elements, the optimal values of elements structure of yield are determined, at which it takes the maximum value. Based on a set of optimal values, theoretical model of studied rice variety is being developed. Then, according to panicles selected in variety, single-row plots are sown for further propagation, rows with parameters of the yield structure elements set same with model of variety are selected, which makes it possible to increase the yield of Mavr rice variety by 39.18 centners / ha or 45.61%.
