The article is devoted to improving the quality of sowing seeds of grain crops and contains the results of laboratory studies of the coil sowing apparatus with the grooves of the sectional coil made in the form of a torus. The paper presents the optimal design and operating parameters of the coil sowing machine with the grooves of the sectional coil made in the form of a torus to ensure the best uniformity of the distribution of seeds along the length of the row. A multifactorial experiment was carried out to substantiate the optimal values of the design and operating parameters of the coil sowing apparatus. The dependences of the uneven distribution of seeds along the length of the row on the speed of the coil, the radius of the forming circle of the torus and the thickness of the separation disk of the spool-sowing apparatus are established.

Main Component

In this paper we consider the structural and technological process of the combine used in the process of separate harvesting of grain crops, as well as a number of its parameters. Among the main units of the combine, we allocate a conveyor and devices for removing beveled stems from under the wheels of the vehicle. The principle of operation of the conveyor at different phases of the Reaper and especially the removal of cut stems from under the wheels of the vehicle during operation of the Reaper. The results of theoretical studies on the establishment of the optimal design of the parameters of the belt conveyor are presented, the ranges of their optimal values are considered and determined. Studies on the establishment of optimal parameters of the screw divider in the Reaper, which is the main component of the device for removal of beveled stems, are presented. Taking into account the optimal design and mode of operation of the screw divider, the correct work is provided to remove the cut stems from under the wheels of the harvester.

Purpose: to determine the efficiency of mineral fertilizers and the agricultural crops response degree for the main groups (cereals, fodder, legumes and industrial crops, potatoes and vegetables) during irrigation in the aspect of resource saving. Materials and methods: the research was carried out in the Central irrigated zone of Rostov region (FSUE “Semikarakorskoe”). The object of research is different groups of agricultural crops, their reaction to the nutrient status at different levels of moisture supply. The soils of the experimental site are represented by ordinary chernozems. Field observations, research and data processing were carried out according to generally accepted methods: B. A. Dospekhov, A. N. Kostyakov, M. M. Goryanskiy. Results: as a result of the research, it was revealed that regardless the fertilizer status, the calculated water regime contributes to the agricultural crops yield increase by an average of 1.6–3.2 times in comparison with dry conditions. The calculated soil water regime contributed to a significant increase in the efficiency of fertilizers relative to rainfed growing conditions. Under different mineral fertilizers backgrounds, the maximum effect from their use increased: in the group of grain crops (spring barley) by 3.09 times, fodder (alfalfa of previous years) by 2.93 times, legumes (peas) by 2.86 times and potatoes by 4.25 times. Conclusions: the greatest effect from the fertilizers application under irrigation conditions was shown by potatoes, vegetables and grain crops. The highest return on fertilizers by an increase in yield was noted in the cultivation of alfalfa (12.67–13.83 kg) and Sudanese grass (22.00–23.44 kg), as well as potatoes (26.37–24.22 kg) and vegetable crops (22.6–33.4 kg). A severe water regime with a slight decrease in the yield of agricultural crops contributes to the irrigation water saving up to 1050–1580 m3/ha, which is very urgent under conditions of water scarcity.

The peculiarities of ecology of certain types of pests breeding in field crops are highlighted. The indicators of the influence of a complex of factors on development and mass reproduction of insects under modern agricultural systems are generalized. The species composition of insect phytophages in new crops is specified. More than 20 species of pests were identified that severely damaged this crop according to the results of the monitoring of the wheat entomocomplex. The analysis of influence of temperature, air and soil on the trophic links of phytophages and development and survival of their stages was conducted. A close connection between the level of productivity and the stages of organogenesis of plants with separate stages of development of the main species of phytophages was established. The analysis of efficiency of application of modern monitoring of a complex of pests at new systems of protection of winter wheat has been carried out. Cereal flies, aphids and other pests are found are found on wheat. The basic ecological and biological peculiarities of the formation of the entomocomplex of winter wheat are determined. The peculiarity of monitoring and control of harmful insect species on winter wheat crops in the forest-steppe of Ukraine is highlighted. The analysis of the modeling efficiency of the number of harmful and useful insect for resource-saving systems of winter wheat protection is carried out. The peculiarities of biology and ecology of pests of stem and of the root system of winter wheat in the region of research are specified. The peculiarities of the formation of entomocomplexes in agrocenoses vary according to certain parameters, in particular the number of soil and interstitial phytophages, taking into account the radius of their daily displacement. It is relevant to determine the total demand of pests in feeding at the actual population of individuals at different stages of ontogenesis of grain crops for effective crop management. The application of resource saving models of the calculation of phytophage dynamics on cereal crops by hydrothermal coefficient at different periods of development of plants and phytophages in the production, which allows to determine the quantitative changes of a separate entomocomplex in grain crops in time and space. The development and introduction of integrated methods for the control of winter wheat pests according to modern agricultural systems in the forest-steppe of Ukraine, which determines the expected loss of grain in the crop fields becomes important.

The article on the basis of scientific methods, theories and approaches provide findings of the research of acute trends and promising lines in development of enterprises in grain-productive sub-complex in view of adapting and applying resource-saving technologies. For example, the authors study principles of using resource-saving technologies in grain production, promising technological solutions of strategic economic and technical direction, reasons blocking the introduction of resources-saving technologies in the process of grain-crops production, as well as a set of resource-oriented measures as an integral part of the organizational and economic mechanism adjusted to modern methods of grain production. Advantages of resource-saving technologies were analyzed in comparison with traditional ways of grain-crops production (both economic and agro-ecological). The authors ground the necessity to use the model of segregated technological flows control in modern technology of grain processing. They provide a thorough analysis of raw protein components market for production of well-balanced fodder in view of adjustment and use of managerial resources-saving approaches and on this basis they draw constructive conclusion and proposals.
