Grytsaj O. Term of sowing, norm of sowing and system of application of nitrogen fertilizer on growing of hard winter wheat in the Step Crimea.

Hard Winter Wheat. Working out of optimal parameters of sowing terms, sowing norms and regime of inputting of nitrogen fertilizers. Multi-factor field experiment. Optimal correlation's of sowing term and sowing norm, rational dozes of nitrogen fertilizers and terms of their inputting are determined in the Crimea for the first time. The results of the experiment are applied in the farms of the Agri-Industrial Complex's and they are recommended for the usage in academical process of the higher educational establishments Hard Winter Wheat.
