For the successful development of animal husbandry in Ukraine, it is necessary to increase the area of pastures for which it is necessary to lend some of the arable land and re-plant some of the existing pastures, creating cultural pastures with a productivity of 60-80 c. fodder units per hectare. For rejuvenation of existing grasslands, the technology of direct sowing with minimal tillage is increasingly used. These technologies include operations to suppress existing grasses and sow the seeds of valuable fodder grasses into grooves specially prepared in the turf. Domestic and foreign experience shows that sowing herbs in pre-treated strips is more effective than traditional methods. The traditional technology of re-insulation of such bows is associated with considerable energy and labor costs and is also erosion-hazardous in areas with a slope angle exceeding 3%. Therefore, for such areas it is necessary to use re-salting technology without completely destroying the turf and to use special seeders of different designs, which perform in one pass the strip tillage, sowing of grass seeds and sealing. Therefore, this method of redevelopment is highly productive and therefore promising in Ukraine. The idea of sowing grass seeds in a cultivated strip of soil in the turf is the basis of the technology of direct accelerated grassland re-grassing. The cultivated strip of soil must meet the agrotechnical requirements for the quality of cultivation in growing grasses. The implementation of the proposed technology of direct strip sowing of grasses in the existing herbage is possible only in the presence of perfect working bodies. Foreign and domestic seeders intended for direct sowing of herbs in the turf do not fully meet the agrotechnical requirements for the quality of processing of the turf strip, so the technology of direct sowing with a developed, active working body in the form of a cutter is proposed.

In Russia for the last 20 years the park of farm vehicles was repeatedly reduced and security of crop production with the soil-cultivating equipment and tractors has significantly worsened. Despite reduction of arable land more than on 40 million hectares, the number of cars on 1000 hectares during the present period are many times lower, than at the countries with the developed agriculture, including in Belarus. The main reasons for reduction of the area of the cultivated arable land, need of their elimination, including due to multiple increase and high-quality improvement of the machine park are specified. The analysis of current trends of development of tillage machines is carried out and the factors influencing this process are shown. The major requirements are increase in productivity due to increase in width of hijacking of cars and power of tractors, ensuring adaptability of cars to agrotechnical requirements due to use of replaceable working bodies and adapters, means of the automated control of quality of work and, in the long term, aggregation with the pilotless power means equipped with GLONASS systems. Types and the predicted need for priority tillage machines taking into account broader performance of pochvovlagosberegayushchy technologies, increases in arable land due to development of 20 million hectares of deposits and updating of the tractor park with his saturation by powerful enegosredstvo are given.

Abstract The development of agricultural technologies, the mechanization of the cultivation of ordinary crops for a long time has gone differently in different ways. The working bodies of agricultural machines process various materials, the number of which is increasing. In addition, the way the same material is processed often changes when trying to improve agricultural technologies. All this forces us to create new mechanisms of agriculture that were previously known. The use of replaceable gear bodies on flat cutting cultivators helps to reduce the energy intensity the process and improve the quality of non-falling soil. To protect against it, various agricultural techniques are recommended: plowing along the entire slope, deepening the arable layer, the formation of irregularities on the surface of arable land in the form of holes, intermittent furrows. The article describes the mechanized protection of the soil of the technological process and technical means for growing crops on erosive lands on the slope. Methodology for improving agricultural machinery for working on the slope of erosive dangerous lands. Ways to increase the stability of the movement of agricultural machines on slopes to improve the quality of technological operations are justified. The operating mode of the active disk needle is described.

For Ukraine's successful entry into Western markets, it is necessary to ensure the competitiveness of its own products, which is achieved through comprehensive mechanization of technological processes, reducing labor costs, increasing yields and quality of products. The most common method of mechanized potato harvesting is undermining the tuber layer with its subsequent destruction and separation of tubers from the heap, which contains plant impurities, soil lumps and stones. The most difficult is the separation from the tubers of strong soil lumps and stones. Attempts have been made to overcome this problem by placing potatoes on well-sifted sandy soils, using special agronomic techniques that reduce, to some extent, the number of lumps. However, such measures are local in nature, not reliable enough and significantly complicate the technology. About 25% of the area occupied by potatoes is heavily littered with stones, the size of which is close to the size of tubers, and about 40% of planted potatoes are placed on soils prone to significant lump formation. Accordingly, the aim of the study was to conduct a comparative analysis of technologies and machines for harvesting potatoes, to develop a model for cutting a potato heap with a ploughshare blade. The research was carried out by technological and structural analysis of technologies and machines for harvesting potatoes. In the process of research methods of comparison and mathematical modeling of technological processes were used. The information base of the research was the work of Ukrainian and foreign scientists on technologies and machines for potato harvesting. On the basis of the comparative analysis of technologies and machines for potato harvesting the main processes influencing agrotechnical indicators of harvesting equipment are revealed, the model of cutting of a potato heap by a ploughshare blade and other constructive and kinematic parameters of working bodies of a ploughshare blade is developed.

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.

Issues related to the reproduction of animals have been and remain one of the most complex and relevant problems of biology and are constantly finding a direct and effective way out into livestock farming practice. The rational use of breeding sheep as producers is limited by the lack of standard, objective methods and methods for the timely assessment of their reproductive ability. The article presents the results of evaluating the sperm production of rams-producers. For the first time, the freshly obtained sperm of rams of Moldavian type producers of the Karakul breed was evaluated using the macroscopic method - ejaculate volume, color and smell, as well as the microscopic method - motility, sperm concentration in the ejaculate, total sperm count in the ejaculate sperm movements (VAP; VSL and VCL) as well as the percentage of abnormal forms of sperm. The experiments were carried out on sheep producers grown on a pedigree farm of the experimental farm of the Moldavian Scientific and Practical Institute of Biotechnology in Animal Husbandry and Veterinary Medicine. As a result of the studies, it was found that the ejaculate volume on average was 0.99 ± 0.04 ml, motility was 0.95 ± 0.02 and sperm concentration 1.51 ± 0.14 billion/ml. The percentage of pathological forms in sperm averaged 13.72 ± 0.61, an indicator that characterizes the high quality of sperm. The average quality indicator of ejaculates obtained from ram-producers of the Moldavian type of the Karakul breed corresponds to physiological standards for the Karakul breed. The average percentage of pathological forms of sperm found in ejaculates indicates that the rams were in good conditions of feeding and keeping. According to research, we can say that the Moldovan type of Karakul rams can be successfully used to obtain high quality ejaculates suitable for freezing sperm at 196°C.
