The purpose of the study is to identify the effectiveness of various types of fertilizers and biologics Bisolbifit on the yield and quality indicators of spring barley grain. Experiments were conducted in 2015-2017 in Ulyanovsk region. The soil of the experimental site is represented by leached Chernozem, heavy loam. The scheme of experience included two factors. Factor A-control; pre-sowing seed treatment with Bisolbifit; NPK in pure form at a dose of 15 kg of active substance per hectare; modified NPK (NPKm) at a dose of 15 kg of active substance per hectare; modified NPK (1/2 NPKm) at a dose of 7.5 kg of active substance per hectare. Factor B (background): zero-without fertilizers; pure ammonium nitrate (NH4NO3) at a dose of 40 kg of active substance per hectare; modified ammonium nitrate (1/2 NH4NO3m) at a dose of 20 kg of active substance per hectare. Inoculation of seeds with a biological preparation was performed by semi-dry etching 1...2 days before sowing at a dose of 400...600 g per hectare of seeds. For the preparation of modified NPK and ammonium nitrate, the biological preparation Bisolbifit was used in a dose of 4 kg per 1 ton of fertilizers. The drug was applied to mineral fertilizer granules on the day of sowing. All types of fertilizers and biologics studied led to an increase in yield. The use of mineral fertilizers in pure form (untreated with biologics) increased the yield by 0.26...0.41 t/ha, modified – by 0.38...0.54 t/ha, biologics – by 0.06...0.19 t/ha, compared with the control (2.67 t/ha). The use of fertilizers and biologics increased the weight of 1000 grains – the best options were with modified NPK at a dose of 15 kg d. V./ha-49.4...53.0 g. the quality indicators of the studied agricultural practices did not have a significant impact. The highest payback of fertilizers by increasing the yield was recorded in the variant with pre-sowing treatment of seeds with Bisolbifit biologics and amounted to 7.7...11.4 kg/kg

The article pays attention to the problem of creating balanced products based on poultry meat and plant raw materials, which can make the nutrition of modern man more rational, restore and maintain metabolic processes, and increase body’s resistance to the effects of adverse life factors. Results of a research on development of formula model of original canned meat and vegetables food for healthy nutrition are given. Quality indicators of product samples are determined: food and energy value, its mineral and vitamin composition. It has been shown that joint and separate inclusion of beans, pumpkin, and Brussels cabbage as a plant ingredient in production technology of meat and vegetable chunks based on chicken meat allows to satisfy daily human need for protein by 14.7-15.4%, individual mineral substances from 2 to 14.1%; various vitamins from 2 to 106.2%.

Porous semiconductors represent a relatively new class of materials formed by the selective etching of a single or polycrystalline substrate. Although porous silicon has received considerable attention due to its novel optical properties1, porous layers can be formed in other semiconductors such as GaAs and GaP. These materials are characterised by very high surface area and by electrical, optical and chemical properties that may differ considerably from bulk. The properties depend on the pore morphology, which can be controlled by adjusting the processing conditions and the dopant concentration. A number of novel structures can be fabricated using selective etching. For example, self-supporting membranes can be made by growing pores through a wafer, films with modulated pore structure can be fabricated by varying the applied potential during growth, composite structures can be prepared by depositing a second phase into the pores and silicon-on-insulator structures can be formed by oxidising a buried porous layer. In all these applications the ability to grow nanostructures controllably is critical.
