Pelekh I. Forage productivity of spring triticale with crucifers and leguminous plants depending on technological techniques in the conditions of right-bank Forest-steppe of Ukraine.

The object of research - the growth and development and forming of the forage productivity of compatible sowings at different applications of technological receptions, connection between biotic and abiotic factors which influence on the productivity. The purpose - to find out dependences of forming of the forage productivity of two-component agrophytocenosis on the basis of spring triticale of the same variety with crucifers and leguminous plants. The methods of research - field, laboratory, chemical, settlement, statistical, rather-settlement. Peculiarities of the growth and development of compatible sowings of spring triticale of the same variety with crucifers and leguminous plants depending on the correlation of sowing rates and doses of mineral fertilizers are presented in the thesis. Completeness of competitive interrelations between plants grown together is revealed. Advantages of spring triticale over annual grain leguminous crops are determined by competitive characteristics. It is proved thatthe change of correlation of sowing rates of the components in agrophytocenosis have influenced on the level of fodder crop productivity. Application of mineral fertilizers in the dose of N90P90K90 and their post-effect substantially influenced on the total output of nutrients per unit of area. Obtained and generalized material enables to recommend to introduce into production the models of growing technologies in spring sowings of mixtures of spring triticale with white mustard (Sinapsis alba), which provide the output of 3,78-4,79 t/ha or with blue lupine (Lupinus angustifolius L.) with dry matter content of 4,09-4,64 t/ha, and in the harvested crops of corn of the same variety that gives the opportunity to get additionally 7,1 t/ha of dry matter or 41 t/ha of green mass. Sphere of using - agricultural production.
