The change of broomcorn millet (Panicum miliaceum L. ) productivity structure under the conditions of differet tllage intensity

The influence of five methods of the main tillage of different intensity on elements of structure of a crop was studied on the bases of millet broomcorn Quartet. Also the indicators characterizing the stability to lodging resistance of millet by options of experience were analyzed. During the research it was determined that the millet productivity increases when the tillage intensity increases as well. The reduction of tillage intensity at millet cultivation leads to sharp reduction of productivity. The reduction of productivity is connected with the decrease in density and survival of plants to harvesting that, in its turn, is directly connected with the quality of planting outfit operation. The impossibility to realize the efficiency potential on zero tillage was connected with the formation of the smallest plant weight, number of grains in a plant that, in its turn, led to formation of small and shrink millet seeds. The formation of a big yield of millet grain in options with plowing became possible thanks to the formation of bigger number of seeds from a plant and higher seed productivity. The maximum losses during millet harvesting in plowing option with a reverse plow were caused by low lodging resistance of plants of this option connected with their high-tallness, bigger length of the top internode and head length.
