Aim of research is to work out theoretical foundations of energy-saving technology of cultivation of the registered and perspective varieties of cereal grasses for fuller realization of their potential of seed productivity fro 4-6 years in comparison to existing 2-3 use of sowings for seed purpose. Methods of research are field, measuring-weighting, quantitative, method of the trial sheaf, laboratory, calculative-comparative, mathematic-statistic. Resource-saving technology of seed cultivation of стоколосу безостого with high sowing and yield characteristics, which has the following elements: annual application of mineral fertilizers N90P45K45, where nitrogen fertilizers should be applied at the beginning of September to prolong duration of the period of effective use, increase seed yield of Bromus inermis L. in wide-row sowings (row width - 45 см) with the sowing rate of 4,4 mln seeds per ha, and provides seed productivity at the level of 0,51-0,62 t/ha of seed. To prolong efficient use of old grass stands of Bromus inermis L. it is necessary to conduct disking with heavy dick harrow to facilitate yield increase by 76%. The technology provides 0,15-0,20 t/ha increase of seed productivity of Bromus inermis L. Energy- and labor costs reduce 1,5-1,8 times. Harvesting this crop using developed technology of determination of harvesting maturity reduces yield losses by 30-40 %. Introduction is carried out in agroformations of different ownership forms of Vinnytsia region on the territory of 150ha. The field of use is agriculture.
