The studies were conducted on long-term (1–34th years of use) mid-ripening three-cut agrocenoses. It was found that during irrigation and application of N260P75K220, an increase in the yield of 1 ha compared to non-irrigated grasses when feeding N180P35K160 amounted to 21–23% on the agrocenoses with awnless brome grass and 30–31% with reed canary grass. Consumption of nitrogen by herbs increased by 20–24 (herbage with awnless brome grass) and 27–29% (with reed canary grass), and phosphorus (P2O5) — by 20–25 and 34–35%. The increase in the removal of potassium and calcium during irrigation did not depend on the composition of agrocenoses and amounted to 17–22 (for K2O) and 47–51% (for CaO). With each centner of dry matter is carried out: 2.1–2.2 kg of nitrogen; 2.2–2.4 K2O; 0.6–0.7 P2O5 and 0.6–0.8 kg CaO. Some of these substances are extracted from the grass soil. To maintain the productivity of grass stands at a high level with long-term intensive use of the meadow, the reserves of nutrients available to herbs in the soil are not enough. Multi-cut use of agrocenoses is possible only with the systematic feeding of each subsequent mowing with optimal doses of fertilizers. In the mowing conveyor system, mid-season grass stands allow to extend the harvesting period of high-quality green mass for haylage and silage by 7–10 days in each mowing. The obtained grass raw materials on three-mowing agrocenoses (during irrigation and without irrigation) in terms of the content of crude protein and crude cellulose meet the requirements of GOST in the first mowing on grass stands with awnless brome – the second class, with reed canary grass – of the third class. In the second mowing of all agrocenoses, the raw material mass corresponded to the second class, in the third mowing – to the first class. According to the content of macronutrients (phosphorus, potassium and calcium) in the dry matter of grass raw materials obtained on agrocenoses with awnless brome and reed canary grass during irrigation and natural moisture, the green mass corresponds to zootechnical norms of animal feeding. The use of high-quality bulky feeds prepared from the green mass of the middle link of the raw material conveyor will reduce the consumption of concentrates and mineral additives in the winter diet of animals.

Currently, the most urgent task in improving the industry of feed production is the creation of green and raw materials conveyors, which will allow an uninterrupted supply of vegetable raw materials from early spring to late autumn for feeding farm animals and preparing high-quality feed. The research has shown that the most optimal time for mowing alfalfaclover-cereals mixtures with high fodder values is the budding phase - the start of flowering of legume grasses in the conveyor system with 10.6-15.2% of raw protein content in the crop. It was noted that the cultivation of meadow clover varieties of various ripening time mixed with a wide range of alfalfa and cereal grasses lead to the decrease in the effect of unfavorable weather conditions and to 15-20% increase in grass mixtures productivity. The article presents recommendations for the extension of the productive longevity of grass stands up to five years using mixtures with different ripening varieties of meadow clover and alfalfa with grass components of a new generation with productivity up to 32.8 t / ha of green mass.  According to the field test of 2013-2017, the article provides data on the green mass productivity of alfalfa-clover-cereals grass stands with the addition of early ripening varieties of grasses, which for two mowings averaged 29.4 t / ha in 2013-2014 and 30.1 t / ha in 2015-2017.  The methods of creating and using grass mixtures have been indicated, the best time for mowing has been defined by conveyor use of them in the Upper Volga region. The scheme of the green and raw materials conveyor with the use of differently ripening grass mixtures, consisting of new species and varieties of forage grasses of different periods of ripening, is given. It has been established that the use of legume-grass mixtures allows to obtain high-quality raw material for the production of bulk feed within 110-120 days, which acts as the way to increase the efficiency of fodder production. An expanded range of fodder grasses creates the conditions for improving the sustainability of fodder production in less dependence on extreme weather conditions.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

This study was begun in 1990 when there was a marked shortage of short fibre raw material for the pulp industry. During the last ten years the situation has changed little, and the shortage is still apparent. It was estimated that 0.5 to 1 million hectares of arable land would be set aside from cultivation in Finland during this period. An alternative to using hardwoods in printing papers is non-wood fibres from herbaceous field crops. The study aimed at determining the feasibility of using non-wood plants as raw material for the pulp and paper industry, and developing crop management methods for the selected species. The properties considered important for a fibre crop were high yielding ability, high pulping quality and good adaptation to the prevailing climatic conditions and possibilities for low cost production. A strategy and a process to identify, select and introduce a crop for domestic short fibre production is described in this thesis. The experimental part of the study consisted of screening plant species by analysing fibre and mineral content, evaluating crop management methods and varieties, resulting in description of an appropriate cropping system for large-scale fibre plant production. Of the 17 herbaceous plant species studied, monocotyledons were most suitable for pulping. They were productive and well adapted to Finnish climatic conditions. Of the monocots, reed canary grass (Phalaris arundinacea L.) and tall fescue (Festuca arundinacea Schreb.) were the most promising. These were chosen for further studies and were included in field experiments to determine the most suitable harvesting system and fertilizer application procedures for biomass production. Reed canary grass was favoured by delayed harvesting in spring when the moisture content of the crop stand was 10-15% of DM before production of new tillers. When sown in early spring, reed canary grass typically yielded 7-8 t ha-1 within three years on clay soil. The yield exceeded 10 t ha-1 on organic soil after the second harvest year. Spring harvesting was not suitable for tall fescue and resulted in only 37-54% of dry matter yields and in far fewer stems and panicles than harvested during the growing season. The economic optimum for fertilizer application rate for reed canary grass ranged from 50 to 100 kg N ha-1 when grown on clay soil and harvested in spring. On organic soil the fertilizer rates needed were lower. If tall fescue is used for raw material for paper, fertilizer application rates higher than 100 kg N ha-1 were not of any additional benefit. It was possible to decrease the mineral content of raw material by harvesting in spring, using moderate fertilizer application rates, removing leaf blades from the raw material and growing the crop on organic soil. The fibre content of the raw material increased the later the crop was harvested, being highest in spring. Removing leaf blades and using minimum fertilizer application rates in-creased the fibre content of biomass.;

The results of studies of thermolysis waste in the environment of overheated water vapor are presented. It is shown that as a result of fractionation from liquid waste thermolysis products, gasoline and diesel fuel fractions can be obtained. It is proposed to use a composite mixture of liquid and solid waste thermolysis products as raw materials for high-grade technical carbon. Studies have shown that high-grade technical carbon can be obtained as raw materials using a composite mixture of rubber waste thermolysis products as raw materials. The technological line of obtaining technical carbon from the products of thermolysis of worn tires is described. Analysis of the ash produced by the process of burning the composite mixture shows that it contains compounds of iron, zinc and silicon. Therefore, this ash is of interest as a high-quality raw material for the production of zinc oxide, as one of the main ingredients of rubber mixtures.

The aim of this investigation was to develop a treatment for combined porcine blood corpuscle concentrate (BCC) and porcine collagenous connective tissue (rind) so as to make more use of these slaughter by-products as an ingredient in a high-quality product such as salami-type sausage. For this study, BCC was preserved, standardized (sBCC) (15% NaCl and 25% protein content), and then added (proportion of sBCC to rind, 15:85) to rind subjected to different treatments designated A, B, and C (A, 2 h at 90°C; B, 5 min at 90°C; and C, 2 h at 3°C). One half of each mixture was again heated (designated A1, B1, and C1; F70, ∼15), and the other half was only cooled (designated A2, B2, and C2). The now colored, highly proteinaceous rind mixtures (A1 to C2) were then cooled and granulated (designated GBR-A1 to GBR-C2). Three of the granulates (GBRA1, -B1, and -B2) proved to be promising new raw materials: their aerobic plate counts were <log 4.0 CFU/g, and their color was appealing (L* values, 23.9 to 25.9; a* values, 17.7 to 22.2; b* values, 11.5 to 12.7). These granulates were then substituted for part (5%) of the meat in the production of fermented raw salami-type sausages. Two of the sausages (SA1 and SB1) were microbiologically stable (containing mainly lactobacilli) and had positive sensory, chemical, and physical properties (e.g., protein, 21%; water activity, 0.90; pH, between 5.3 and 5.4 on day 36) meeting all standards for commercially produced raw sausages. Our investigation yielded a practicable way to treat and combine two slaughter by-products for use in a high-quality meat product.

Ethnographic examples of stone-tool makers in Australia and archaeological examples from three different areas in the western United States indicate that the availability of lithic raw materials is an important variable conditioning stone-tool production technology. Attributes of availability such as abundance and quality of lithic raw materials condition the production of formal- vs. informal-tool types. Poor-quality raw materials tend to be manufactured into informal-tool designs. High-quality lithic raw materials tend to be manufactured into formal-tool designs when such materials occur in low abundance. When high-quality materials occur in great abundance both formal- and informal-tool designs are manufactured. Other factors, such as residential mobility or sedentism, are found to be less-important determinates of lithic-production technology.

Ancient Iraq is very well known as an agricultural economic country, especially, the middle and the southern parts of Mesopotamia, which was called “the Land of Sumer and Akkad “, it's a very rich agricultural country. Sumer's economy was based on agriculture, fishing, and cattle and sheep breeding. Lived on the products of the fertile, irrigated soil, and this situation was clearly reflected in the cuneiform texts unearthed from many sites from the third and second millennium BC. And due to the young geological composition of Mesopotamia, the alluvial plain of ancient Sumer lacked so much important raw materials, these of materials were needed by the craftsmen of Sumer and Akkad for the industry, works of art and daily life. These raw material were, deferent kinds of stone, timber, and metal, therefore, the need for these materials led to exchange what the people had from the agricultural production and industrial goods and material produced by the workshops of temple or palace, such as: animal hides, leather manufactures, wool, oil, cereals, dates, textile, wild and domesticated animals,…etc., also what not existing in the country ([i])   Leemans, W.F., "The Importance of Trade", Iraq-39, (1977), p. 4.
