Object of the study - the processes of growth, development and formation of photosynthetic, feed and seed productivity of oil radish plants under different elements of the cultivation technology. The aim of the study is to identify dependencies of feed and seed productivity formation as well as feed and seed quality of oil radish on the influence of sowing terms and methods, seeding and fertilization rates under conditions of the right bank Forest-Steppe. Research methods - field method combined with metric and visual observation - to determine interaction of the research object with natural and studied factors; weight method - to determine individual plant productivity and yield; biochemical method - to determine chemical composition and nutritious value of feed; physiological method - to determine photosynthetic activity of crops; statistical methods: dispersion, correlation and regression, cluster - to determine probability of data, power of dependencies, formation of correlation models; calculation and comparison - to determine economic and energy efficiency of the researched methods of the cultivation technology. The investigation's results on the learning of peculiarities of growth, development and formation of photosynthetic, forage and and seed productivity of oil radish varieties depending on the period of sowing, method of sowing, seed rate and fertilizing are presented in the thesis, besides the economic, bioenergetic evaluation and its technologies and its competitiveness are given. The obtained and summarized material enables to recommend and to introduce into production the most economically profitable and the most competitive technologies of oil radish growing under the conditions of the right-bank Ukrainian Forest-Steppe, that provides the leaves and stems mass output at the level of 37,8 - 42,8 t/ha, the output of dry matter at the level of 5,5 - 5,8 t/ha and the digestible protein - 0,60 - 0,71 t/ha with the level of biological seed productivity 2,0 - 2,7 t/ha. Introduced. Optimized elements of the technology of oil radish production were validated and implemented in 2012 in the farms of Vinnytsia region SE "Illinetske" of Illintsi region on the area of 5.3 hectares, SERF "Artemida " of Kalynivisky region on the area of 4.7 ha and " Skomoroshkivske" Ltd of Orativ region on the area of 8 hectares, where the growth of leaf and stem mass yield was provided at the level of 8.6 - 11.7 t/ha and seed yield at the level of 0.54 t/ha. Some developments and recommendations of the author are included in the methodological and technological process by the Pre-Carpathian State Agricultural Experimental Station of the Institute of Agriculture of the Carpathian region of the NAAS, laboratory of technical, fodder and vegetable crops of Ustymivska Experimental Station of the Institute of Crop Production named after B.Y.Yuriev of the NAAS, Department of Production and Marketing of Plant Products of the Department of Agricultural Development of Vinnytsia Regional State Administration. Field of introduction - agriculture.
