Abstract

Winter barley were grown under field conditions during the 2004 growing season and residual influences of liming with carbocalk (waste of sugar factory) and phosphorus fertilization with MAP (monoammonium phosphate) were tested. By using the lowest lime rate (15 t ha ⁻¹ ) barley yield was increased by 30%. Overliming (90 t ha ⁻¹ ) resulted by significant yield decreases in comparison with application 15 and 30 t of lime. Using of 45 and more lime per hectare protein contents was significantly increased. In general, liming considerably influenced on grain composition of barley. For example, by application of the lowest lime rate, grain P, K, Ca, Mg, Fe, Cu, Mo and Na significantly increased in comparison with the control. Differences of grain composition among lime treatments were mainly non-significant. Ameliorative P fertilization significantly increased grain yields of barley up to 25% in comparison with the control. In general, grain composition differences among applied treatments were mainly non-significant because significant differences only for P and Mn (increasing trend due to P application) as well as for Zn and Mo (decreasing trend) were found.
