Tomashov S. Formation of productivity and quality of winter rape seeds with mineral fertilizers, sowing and application of growth regulator in the steppes of the Crimea

The object of researches is rape winter in the system of agrotehnologii. Purpose of researches - in the ground-climatic terms of steppe Crimea to define the optimum term of sowing of rape of winter in combination with application to the regulator of growth of group of azol on a background the fertilizers, which provided the optimum terms of growth, development of plants and receipt of high harvests, in the unirrigated terms after clean steam. Methods of researches - the field; laboratory; mathematic-statistical; computation-comparative. Results of researches - For a theory: First for the unirrigated terms of steppe area of Crimea the researches directed for development of elements of high quality agrotechnics of growing of rape of winter by experimental determination optimum term of sowing and necessity of application of retardant are conducted, the best background of feed and his influence on the indexes of harvest and quality of seeds is definite. For practice: To agricultural production the improved technology of growing of rape of winter is offered, in particular combination of optimum term of sowing - on September, 5, and application of the Folikur preparation on a background bringing of fertilizers by the complete norm N80P30 from an autumn.
