Cultivation technologies issues of spring barley varieties (Hordeum vulgare L.) (Vladimir, Moscowskiy 86, Jaromir, Nur) grown for the brewing, fodder and food purposes at soddy-podzolic soils are considered. The productivity of new barley varieties raised with increase in technology intensity, the best results were received for varieties Jaromirn and Nur, their productivity reached 8-11 t/ha at high-intensity technology. Application of high dozes of mineral fertilizers in the combination with differentiated crops processing by plants protection means resulted in increase of photosynthetic potential of the crop which varied depending on meteorological conditions, norms of seeding and the cultivated variety. This parameter changed from 2,85 up to 6,82 million m² / ha ∙ day on the average for the years of researches. The grain of new and perspective varieties of spring barley grown at base technology perfectly corresponded to the requirements of established state standarts for the grain used for brewing. Insignificant increase of protein content by 0,4-1,4 % at intensive technology was noted. The grain production received with application of highintensity technology, completely complied with requirements for fodder and food grain.
