Abstract

The purpose. To justify expediency of overlapping production operations of sowing cereal crops and importing basic and starting doses of mineral fertilizers at application of the combined machine-tractor assembly unit. Methods. At study they use methods of field experiments with application of standard equipment. The design of experiments is realized with the use of correlation methods and methods of numerical calculations on PC. Results. Comparative study of quality of sowing barley while using basic and upgraded fertilizing-sowing assembly units have shown the following. Variation factor of depth of sowing seeds by basic assembly unit made 8,2% (by combined one – 4,7%); equitability of seeds longwise the row for basic assembly unit was 63,8% (for improved one – 84,9%); field germination rate of seeds at sowing by basic assembly unit made 80,4% (improved one – 87,4%). Thus, application of the combined fertilizing-sowing assembly unit increased equitability of seeds longwise the row. Alongside with it increases field germination rate of seeds, and decreases variation factor of depth of sowing seeds in furrow. Conclusions. By results of field pilot researches increase of productivity of spring wheat and barley is fixed at application of the combined fertilizing-sowing assembly unit with simultaneous importation into soil of the basic dose of mineral fertilizers and sowing cereal crops with importation of starting dose of mineral fertilizers as compared to known schemes of such operations. The gained results confirm expediency of overlapping the specified production operations at one passage of the combined machine-tractor assembly unit.
