During growth, kernel of cereals can be provided with carbohydrate and nitrogen (N) from the translocation pre-anthesis accumulated reserves stored either in vegetative plant parts or current assimilation during development. This study was conducted to assess effects level cultivars on dry matter N accumulation mobilization post-anthesis. Twenty two-rowed spring barley (Hordeum vulgare L.) were grown a non-calcareous chernozem soil four growing seasons (1995-1998) atNovi Sad (45°20'N, 15°51'E,86 m a.s.l.) at two levels. Dry before anthesis ranged less than 50% unfavorable 90% favorable conditions. occurred conditions only. Pre-anthesis represented 57-92% 54-129% total maturity low high levels, respectively. Translocated 41-85% 37-153% grain level, losses when exceeded 150 kg/ha. filling negative correlation anthesis.
