In the conditions of climatic changes, an important condition for sustainable field fodder production is the use of species with increased resistance to stressful hydrothermal factors. Such crops include the white sweetclover burdock (Melilotus albus), the crops of which form a high and stable yield under any weather conditions. In fodder production, the crop can be used for harvesting hay, silage, and also fed as green and pasture fodder. Despite the high fodder and agrotechnical value of white sweetclover gorse, currently available scientific information on the technological features of growing it for fodder in mixed crops with cereal crops is insufficient. The purpose of the research was to establish the peculiarities of the formation of the productivity of the vegetative mass of Melilotus albus in single-species and binary crops with cereal components, depending on the technological methods of cultivation. The research was conducted during 2015-2017 at the experimental fields of the Department of Fodder Production, Land Reclamation and Meteorology in the conditions of the SS NULES of Ukraine "Agronomic Research Station" on typical low-humus black soil. It was established that the maximum yield of green fodder was provided by the technological model, which provided for the cultivation of binary crops of Melilotus albus with Sudanese grass at the rate of sowing of leguminous crops of 16 kg/ha and the application of N60P90K90 – 51.5 t/ha, which exceeded the control (single-species sowing of Melilotus albus with with a seeding rate of 16 kg/ha) by 13.4 t/ha. This variant had the highest intensity of growth of fodder mass already from the thirtieth day after germination and the best foliage of fodder mass in the period of cutting ripeness – 39.73-41.17 % or 10.80-13.97 t/ha. The smallest increase under such an interaction of factors was provided by leguminous-cereal phytocenosis with millet – 5.4 t/ha
