Response of winter barley to liming

The field experiment with increasing rates (0, 5, 10, 20 and 40 t ha-1) of fertdolomite (24.0 % CaO, 16.0 % MgO, 3.0 % N, 2.5 % P2O5 and 3.0 % K2O) was conducted in the autumn of 2008 in Badljevina (Pozega-Slavonian County). The experiment was conducted in the randomized block design in four replicates and basic plot size was 37.5 m2. Acid reaction (pH in 1n KCl 5.08) and low levels of plant available P and K (AL-method: 8.3 mg P2O5 and 13.2 mg K2O 100 g of soil) are main characteristics of the soil. Aim of this study was short review of published the 3-year results of the field crops in rotation and detailed results of unpublished data regarding response of winter barley in the 2012/2013 growing season. Application of the highest rate of fertdolomite resulted in the first year of testing by maize yield reduction for 12%, while in the remaining rates yield were in level of the control. In the next year winter wheat responded by yield increases up to 10%. As affected by the higher rates of ferdolomite (20 and 40 t ha-1) grain yields of barley in the 2011 growing season were increased compared to the control for 20% and 51%, respectively. Also, barley considerably responded to grain yield increase in the 2013 growing season because yields were significantly increased for 15% and 44%, for the treatments 20 and 40 t ha-1, respectively.
