INFLUENCE OF WHEEL MOTORS OF THE SEEDING UNIT ON GRAIN YIELD OF CORN
The purpose of research: еstimation of influence of soil compaction by running wheels of the tractor with a row seeder on productivity and economic efficiency of cultivation of corn on grain. Research methods: hypothesis, experiment, field observation, laboratory, visual and comparative calculation method. Research results: Field studies were conducted in soil and climatic conditions of Western Ukraine. The experimental field was characterized by sod-podzolic light loam soils. Climatic conditions of research – the average daily air temperature during the growing season of corn - +16.9 ° C, rainfall – 263 mm.

In the process of performing the technological operation of such a sowing unit, two sowing machines work on the tracks of the tractor wheels.

The grain yield of corn sown on the tracks of the tractor was lower by 2.27-2.51 t/ha (16.5-27.9 %) compared to this figure on uncompacted rows. Seed yield of the studied hybrids (average value for all eight rows of rows) is 8.33-13.21 t/ha. Due to the fact that in ¼ rows (in two rows on the tracks of the tractor) recorded lower yields, the average yield of corn grain decreased by 0.57-0.66 t/ha (4.1-6.9 %) compared to this figure on uncompacted rows.
