Skoromnyi S. Influence of biotic factors and technological receptions on forming of heterogeneous seed of soy in the conditions of north-eastern part of Forest-Steppe of Ukraine

Subject: formation of soybean seed of diverse qualities. Aim: to determine peculiarities for the formation of soybean seeds of full value and to develop methods for improving souring and yielding qualities of seeds. Methods: field, laboratory-field, measuring-weight, mathematical-statistical, calculated-comparative. Novelty: for the first time in the conditions of the north-eastern Forest-Steppe of Ukraine there are determined some peculiarities for the formation of soybean seed of diverse qualities depending on a cultivars, bio- and abiotic factors. Results: a method for soybean seed grading for elasticity and a method for its desinfection with aerial-ozone mixture and fire are worked out. Application stage: the results have been implemented into farm-agricultural production units in the Kharkov Oblast on the area of 125 ha with 114,1% profitableness. Application area: soybean seed production
