The field experiment with increasing rates (t ha-1: 0, 5, 10, 20 and 40) of fertdolomite (24.0 % CaO + 16.0 % MgO + 3.0 % N + 2.5 % P2O5 + 3.0 % K2O) was started in autumn 2008 on Badljevina pseudogley (Bjelovar-Bilogora County). Each treatment was represented by two basic plot of 75 m2 area and at early growth stage it was divided in two sub-plots for receiving four replicates. Maize (2009) and wheat (2010) were grown in rotation. Harvesting of maize was made earlier for three weeks compared to usual terms because of drought (45% lower precipitation in May-Sept. 2009 period compared to 30-year mean 1961-1990). Application of enormous rate of fertdolomite resulted by maize yield decrease for 10% compared to the control mainly because of plant density reduction. The effects of liming were considerably higher in 2010 compared to the previous year. For example, as affected by liming grain yield of wheat were increased up to 9%. Also, lime considerably influenced on improvement of grain quality parameters (protein 12.91% and 13.85%, gluten 31.7 and 35.2%, sedimentation 39.6 and 51, 6 sec, for the control and 40 t lime ha-1, respectively). |
