Pelekh L. The optimization on technological techniques of oat in mixture crops with crucifers and leguminous plants in the conditions of right-bank Forest-steppe of Ukraine.

The object of research is processes of the growth, development and forming of the forage productivity of oat with crucifers and leguminous mixtures after different technological receptions, copulas between biotical and by abiotical factors, by the norms of mineral fertilizers, norms of sowing of seed in mixture. The aim of work is to study the processes of growth and development of oat, radish oil, mustard white, lupine white and bean forage, depending on correlation of norm sowing by components in mixture, to learn influence of norms, mineral fertilizers on forming on the productivity of components in the compatible sowing, find out cross-correlation copulas between the quantitative and high-quality signs of harvest and agrobiological indexes, set optimum correlation of norms of sowing of components in the compatible sowing and their influence on the level of the productivity of green mass, to study changeability of chemical composition dry matter of components annual culture depending on factors, to give the economic evaluation efficiency of technology growing of the compatible sowing, compare the models of technology growing after a competitiveness. The methods of research are the following: field, visual, measuring and weighing, electro-photometric and chemical, mathematically statistical. Results of researches the features of growth development of plants of oat are in-process expounded with crucifers and leguminous cultures depending on correlation norms of sowing and norms of mineral fertilizers. Found out plenitude of cross-correlation intercommunications between the quantitative and high-quality signs of harvest and agrobiological indexes. Production control and introduction of improved technologies were carried out in agro-formations of Vinnitca region on the area of 94 ha. The branch of research is agriculture.
