Gladka A. Peculiarities of growth and influence of agricultural measures on the productivity of winter cereals crops in the northern steppes of Ukraine

The object of study - the processes of formation of yield and quality of grain in various winter cereals crops and farming practices to optimize the conditions for their growth. The goal - to study peculiarities of the productive potential of various winter cereals crops depending on the time of sowing and predecessors. Methods - scientific methods of analysis and synthesis, experiment, hypothesis, design, field, laboratory, comparative, computational and statistical techniques. Results - provide agricultural methods recommended in the northern Barrens receiving, respectively 3,4-6,6 t per ha, 2,9-4,6, 3,1-5,1 and 3,5-5,1 t/ha grain. Reduction in yield for the deviation from the optimum sowing time is from 0.65 to 2.0 t / ha. Research results are tested in a production environment Sinelnikovski Selection Experiment Station and introduced in farms Sinelnikovski region Dnipropetrovsk region in the area 5.7 hectares. The economic effect of the introduction of scientific research was 192-430 UAH/ha. The novelty - in the northern steppes of Ukraine against various predecessors and sowing first study of growth, development and the formation of grain productivity in the region, the most common winter crops, which differ in adaptive and genetic potential. A comparative analysis of the effectiveness of their cultivation in different regions and Agriculture technology of the region. The optimum sowing time of wheat, barley, rye and triticale winter for placing the black and after a couple of sunflower An economic evaluation of the effectiveness of their cultivation. Industry - Agriculture.
