Popov S. Agroecological substantiation of soft winter wheat growing technology in the area of low and unstable moisture

Object: The forming of agrophytocenosis productivity , adaptation and technology elements biologization of soft winter wheat growing in a left-bank forest-steppe zone of Ukraine. Aim: agro-ecological substantiation of soft winter wheat growing technology in the zone of insufficient and unreliable moistening the eastern steppe of Ukraine and the development of resource saving and environmentally safe technology. Methods: Field , laboratory , comparative calculation , statistical . Novelty: For the first time in Ukraine it was solved an important scientific problem of agro-ecological substantiation of soft winter wheat growing basic technology in the area with lack and unstable moisture. Also the level and dynamics of ecological stability , plasticity and varieties adaptability, that depending on growing conditions, was set. Results: As a result of the scientific problem solving the three models of soft winter wheat growing technology were grounded and rooted in production: adaptive, resource saving and intensive for the producers to their level of material and energy security, that is essential for the crop agriculture industry development in Ukraine. The realization possibility of the new winter wheat varieties yield and grain quality potential, that depends on the agro-ecological factors and the complex elements of the cultivation adapted technology, was set. The biologization items of winter wheat cultivation technology adapted to the weather conditions, that involves using the green manure fumes , biological growth regulators and micronutrients, that ensures the formation of the stable food grains yield, were designed. The optimum mathematical model of adapting the complex elements parameters of the modern winter wheat varieties cultivation technology was developed. The two state patent for utility model "method of increasing the winter crops yield of different planting dates for corn silage" and "Method of increasing the winter grain crops yield on nonfallow predecessors" were received. Application stage: advanced technology of soft winter wheat growing were laid in the guidelines basis of the APP Kharkiv region scientific support center and were introduced into farms of Kharkiv, Poltava and Luhansk regions with a total area of over 350 hectares. The experimental research results and manual " Workshop on common general agriculture land and reclamation land " are used in scientific and experimental process and on lectures and practical courses with students of Kharkov NAU nd.a .V.V. Dokuchaev , training courses listeners, managers and specialists of agriculture. Application area: Agricultural enterprises of all forms of Ukraine agriculture ownership.
