The purpose of the research is to investigate the quality of inter-row tillage with a rotary harrow depending on the speed regimes in conditions of high soil hardness.Research methods: theoretical - analysis of information resources and research results of rotary harrows; experimental field - testing of the machine in the economic conditions of LLC "Nosivka Agro", village Ploske Nosiv district of Chernihiv region with the fixation of agronomic indicators; instrumental measurements and expert evaluation; statistical - mathematical processing of the obtained indicators.Results.Experimental field studies of the influence of the speed modes of the rotary harrow BZR-9.0 on the efficiency of inter-row cultivation have been carried out.The nomenclature of quality criteria and their achieved level have been established by expert evaluation.It has been analytically established that the rotary harrow mulches the topsoil well, destroys the soil crust, loosens the soil and destroys filamentous weeds, thus creating ideal conditions for the initial development of the plant root system and providing a strong start to their growth. Conclusions. Rotary harrows, widely available on the Ukrainian market, are increasingly in demand as an effective tool for weed control and soil crust destruction in order to improve aeration and water saturation of crops in conditions of increased soil dryness. Theoretical analysis of information sources confirms that needle harrows can be successfully used for continuous and inter-row cultivation of crops in small and medium-sized farms. The physical parameters obtained as a result of experimental researches testify that with change of speed from 9 km / h to 15 km / h the harrow tooth rotary BZR-9,0 in interrow spacing with a protective zone of 11 cm provides qualitative cultivation of soil with a sufficient level of agrotechnical indicators - degree of destruction. soil crust in the range of 91-98 %, and the percentage of damaged plants is at the level of excellent and satisfactory values. There are no undamaged areas of crust with an area of more than 5 cm2, which significantly impede water and air permeability.
The purpose of the research – to conduct experimental testing aimed at evaluating of the automatic mobil milk receiving unit of domestic production. Research methods. During the testing of the automatic mobil milk receiving unit of domestic production the quality of the technological process was determined using the methods given in DSTU 7435: 2013 and DSTU 3662: 2018, operational-technological and economic evaluation was carried out according to DSTU 8424: 2015 and DSTU 4397: 2005, safety and ergonomics were determined according to DSTU EN ISO 12100: 2014. Research results. According to the results of experimental testing, it was found that the automatic mobil milk collection unit АППМ-1 at the appropriate level measures the amount of delivered milk with an error of 0,9 %, which meets the requirements of the TU (up to 3,0 %). The water temperature for washing equipment is 58 °C, which meets the requirements of TU (50-60 °C). The system of washing of surfaces of the automatic point which are in contact with milk provides high-quality washing of the equipment, existence of an intestinal stick (coli-titer) makes > 1,0 that meets requirements of TU (not less than 1,0). The period of acceptance, transportation and delivery of milk to the processing plant for one working cycle of procurement is 3,3 hours, which meets the requirements of the TU (not more than 4 hours). Productivity of the automatic point of reception of АППМ-1 milk during performance of technological process on reception, registration and transportation of milk in a radius of 30 km makes 363 l / h, for a radius of transportation in 50 km - 330 l / h, 100 km - 280 l / h, that meets the requirements of TU (275-360 l / h). Specific fuel consumption (liquefied gas) is 7,4 liters per ton of milk collected. Conclusions. The first experimental testing of the domestic automatic milk collection point APPM-1 showed that the equipment satisfactorily performs the specified technological process of acceptance, registration, short-term storage of milk obtained in private farms and transporting it to processing enterprises, according to the quality of the process meets the requirements of technical conditions. The automatic milk collection point АППМ-1 is characterized by a high technical level and can be used in Ukraine.
