Use of the automobile chassis on technological operation on plant protection

Annotation Purpose. Reducing the cost of crop production by creating technical means that ensure the use of imported plant protection products or fertilizers under the flow-through technological scheme. Methods. The theoretical and analytical methods of analysis of the technological process of introducing means of protection using the basic laws of economic theory using a personal computer. Results. The paper proposes ways to reduce the cost of crop production by reducing the direct operating costs of technological operations for plant protection through the use of these technological operations of agricultural machinery units (AMU) based on off-road chassis GAZ-66 and sprayer OA-3000. The technical and technological characteristics of AMU GAZ-66 + OA-3000, economic efficiency of GAZ-66 + OA-3000 in comparison with the MTZ-920 + OShSh-3000 machine-tractor unit is given. Conclusions. Use AMU based on car chassis GAZ-66 and the OA-3000 automobile sprayer on performance of technological operations on the use made of plant protection products give the chance to increase productivity by 53% and to reduce direct operating costs in 2.1 times in comparison with machine-tractor units on the basis MTZ-920. Keywords: machine agricultural unit, car chassis, sprayer, cost of production, plant protection products.
