Agromeliorative treatment of drained soils
The paper shows efficiency of volumetric slotting, methods of basic treatment and their combined effect on the performance of field crops and agrophysical properties of drained soils. The experiments were carried out at the Gubino experimental agro-polygon of the All-Russian Research Institute of Reclaimed Lands (VNIIMZ), located at the reclamation facility in the Tver region. The soils under experiment are cultivated soddy-podzolic, light loamy gleyic, formed on a thin binomial, drained by closed pottery drainage method. Volumetric slotting was carried out to a depth of 4550 cm with filling the subarable part (3050 cm) with crushed straw, plant residues mixed with a humus layer. The slotting was carried out with a specially designed tool. Slot width 16 cm, slotting pitch 140 cm. Efficiency of ridge plowing, volumetric slotting of the soil and their joint action has been determined. The yield of oats during ridge plowing increased by an average of 0.36 t/ha (12.0 %) over 5 years, in case of slotting by 0.60 (20.0 %), in case of combined action by 0.82 t/ha, or 27.0 %. The share of slotting in the total increase in yield on average over 5 years was 73.2 %, ridge plowing 26.8 %. The positive effect of slotting on the yield of field crops during the experiment was observed for 6 years. The total increase in yield from volumetric soil slotting on oats for 5 years was 3.0 tons of grain per 1 ha, with combined action with ridge plowing 4.1 tons of grain per 1 ha, or 36.7 % higher. The increase in the yield of oats, both with soil slotting and with ridge plowing, occurred due to an increase in the number of productive stems and the mass of grain in the panicle. With slotting, these indicators increased by 8.4 and 11.3 %, with ridge plowing by 6.1 and 12.0 %. The results of the research can be used in the development of agro-reclamation tillage systems and in adaptive agricultural technologies for the cultivation of spring grain crops.

Antioxidant activity of new varieties spicy-aromatic and essential-oil plants
Spicy-aromatic and essential-oil plants are among the most important food, technical and medicinal plants; their green mass, seeds and essential oils are used in various sectors of the economy. The purpose of the research was to study the indicators of antioxidant activity of the green mass of new varieties of spicy-aromatic and essential-oil plants. The research subjects were new regionalized varieties of oregano, hyssop officinalis, common basil, fine-flowered basil, fragrant onion, multi-tiered onion, fragrant rue, blue fenugreek, large-rhizome geranium and borage. The yield of green mass during flowering phase was studied in field experiments according to generally accepted methods. In laboratory experiments, the content of vitamin C and carotene was studied according to standard methods, content of polyphenolic compounds according to method of calibration schedule based on a standard substance rutin. As a result of field and laboratory studies, it has been determined that the yield of the green mass of the studied crops was 125280 c/ha, vitamin C 27.069.0 mg/100 g, ca- rotene 7.540.7 mg/kg, polyphenol compounds 9.6374.2 mg rutin/g. The studied spicy-aromatic and essential-oil plants in terms of antioxidant activity (content of polyphenol compounds) can be grouped into the following series: oregano > large-rhizome geranium > hyssop officinalis > basil > borage > fragrant rue > blue fenugreek > perennial onions. Among the varieties of oregano and hyssop, higher rates of antioxidant activity are noted in varieties with a more intense corolla color (rich pink in oregano, blue in hyssop). The results obtained on the yield of marketable products and antioxidant activity make it possible to more fully evaluate spicy-aromatic and essential-oil plants with the prospect of their use in various sectors of the economy, primarily in the development of functional products.

Insects as an alternative protein source in poultry nutrition: review
In todays world, poultry farming is the most dynamically developing branch of agro-industrial complex, providing the population of the planet with products of animal origin. However, poultry meat producers in developing countries face the challenges of high cost and low-quality poultry feed. Limited use of available protein sources forces professionals to consider using alternative protein sources such as forage insects. Due to high content of fat (3040 %) and protein components (4060 %) and wide distribution, insects are a cost-effective and potentially sustainable feed resource for poultry feeding. The conducted studies confirm that insect meal (larvae of black soldier fly, housefly, large mealworm, silkworm, grasshopper and locust) can be considered as a potential replacement for fishmeal and soybean meal in poultry feed mixtures. A review of scientific literature is presented, which highlights the use of insects as a source of protein and biologically active substances (polyunsaturated fatty acids and antimicrobial peptides) for poultry feeding and possibility of large-scale insect cliching for feed production. Information is provided on the chemical composition, nutritional and biological value of insect-based feed meal in comparison with soybean and fishmeal. There is practically no information in the literature about the negative consequences for chicken growth when using insect meal in feeding. Most scientific publications indicate that physiological indicators and productivity, when insect meal was used in poultry feeding, were practically not inferior to those in birds fed with soy or fishmeal. Thus, the use of insects as a feed component in poultry farming is a promising aspect for sustainable development of animal husbandry, which allows solving the problems of waste processing and rational use of feed resources.

Results of production tests and economic evaluation of a rotary beater-combing device on a flax harvester
The results of production tests of a rotary beater-combing device developed at the EE BSAA for separating seeds from flax stalks in the implementation of combine harvesting technology are presented in the paper. As a result of the research, regularities were determined for changes in the purity of threshing, the degree of damage to seeds and stems depending on the thickness of the strip of flax stems threshed by the developed device installed in the Dvina-4M flax harvester. Regularities of changes in the purity of threshing and the degree of damage to flax stalks from the gap between the rotor and deck in the phase of yellow and brown ripeness of flax at different rotor speeds have been determined. The results of comparative tests of a flax harvester equipped with a rotary beater-combing device in comparison with a flax harvester equipped with a single-drum combing device are presented. Use of a rotary beater-combing device on a flax harvester allows to increase the performance of the combine by 8.7 %, reduce the total loss of seeds by 32.35 % and 4.27.32 % as a result of undercombing, reduce damage to flax stalks affecting the output of long flax fiber by 38.01 %. Also, a decrease in the volume of the resulting flax heap was noted when using a rotary beater-combing device, depending on the quality of the stem and the phase of flax ripeness, by 28.556.3 % in comparison with the comb apparatus. The annual economic effect of the rotary beater- combing device will make 7831 rubles, the economic effect per 1 ha 156.6 rubles in prices of the I quarter of 2023.

Scientific substantiation of use of food plant raw materials for production of specialized flour food products in cases of pathologies of metabolism protein component
There is a number of diseases caused by metabolism protein disorders. The treatment requires dietary therapy with specialized food products. Information on diseases associated with metabolism protein disorders protein in this paper, as well as restrictions in the formulation of diets, analyzing vegetable crops and their products, which can be used in the production of flour food products intended for people with metabolism protein disorders. Use of raw materials in development and production of such products is often not confirmed by the results of chemical composition and, as a consequence, is groundless and inexpedient. Vegetable raw materials characterized by low protein content or absence of gluten have significant differences in technological properties compared to wheat flour, which forms the basis of most flour food products, which requires adjustments in the formulation or technological process of production of various groups of flour food products. Samples of buckwheat flour, including whole-milled flour from green buckwheat, rice and corn flours, sorghum flour, native potato and corn starches from different producers were used in the study. During the research we used common and special methods of determining the chemical composition, organoleptic and physical-and-chemical quality indicators, technological properties of the products and their chemical properties.
