“…Conversely, Baethgen et al (1995) previously suggested that increased nitrogen rates in malting barley did not have a significant effect on grain weight. A three-year study conducted by Gonzales Ponce et al (1993) showed that grain yield increase in two-row barley induced by increasing nitrogen rates (0 -160 kg ha -1 ) was mostly attributed to the increase in spike number per m -2 , with grain weight remaining constant or even increased during years receiving higher rainfall. Analysing the relationship between grain yield and yield components in two-row barley, Barczak and Majcherczak (2009) reported the highest correlation between grain yield and spike number per m -2 , as well as between grain yield and grain number per spike, regardless of soil nutrient supply.…”

“…Increased nitrogen levels induce more intensive vegetative growth, higher spike number m -2 and reduced grain number per spike, and have variable effects on grain weight (Christensen and Killorn, 1981;Gonzales Ponce et al, 1993;Paunović et al, 2008;Madic et al, 2009). Gonzales Ponce et al (1993) suggest that the soil moisture × nitrogen level interaction is the major determinant of grain yield in barley.…”

The stationary multi-factor trial was established in 1974 on experimental station of Borovce. There are 40%, 60% and 80% share of cereals. Grain yield by 40% share of cereals was statistically higher (6,50 t ha -1 ) than by 60 in the crop rotations trial % and 80% share of cereals (6,23 t ha -1 ). Grain yield of spring barley by 80% share of cereals was statistically lower (4,05 t ha -1 ) than by 40% (5,04 t ha -1 ) and 60% share of cereals (5,03 t ha -1 ). Different proportion of cereals in a rotation system had a significant effect on the abundance of rhizobia, cellulolytic and denitrification bacteria. At combined fertilization (mineral plus organic) we observed higher abundance of bacterial spores, Azotobacter spp., denitrification, cellulolytic and nitrification bacteria in comparison with the variant without organic fertilization. The highest metabolic diversity and average utilization of carbon sources by microbial communities was recorded in soil samples collected from crop rotation system with 40 % contribution of cereals and combined fertilization with added organic fertilizer Veget.

Physiology describes the operation of a plant at the biochemical, cell, tissue, organ and whole plant levels, recognizing that all of these are under the control of the plant genome. In the case of crop plants we are interested in how the combined operation of all plant's functions leads to the production of the harvestable component which, in cereal crops, is generally grain. Broadly speaking, the most important of the physiological activities in a crop plant with regard to yield are dry matter production, nutrient uptake, plant component partitioning and the processes of development (especially grain filling and the other aspects of yield component development). The developmental processes occur sequentially in time and involve progressive shifts in physiology. As barley (Hordeum vulgare L.) is a feed grain and a major source of malting grain for beer and spirits, aspects of physiology that affect the amount of grain produced and its quality (the amount of energy and protein) are of special interest.
