Sažetak
The aim of this paper was to compare the impact of liming eight years after application and mineral fertilization on soil chemical properties and wheat grain and straw yield. The soil was determined as a dystric luvisol with low pH and low nutrients availability. The field trial was setup in a randomized block design in three replicates in Zelčin (45°36'45.48"N, 18°22'4.74" E) in the eastern Croatia. The treatmants were: 1. control, 2. liming (10t ha-1carbocalc), 3. mineral fertilization (160 kg N ha-1, 150 kg P2O5 ha-1, 200 kg K2O ha-1) 4. liming and mineral fertilization, 5. liming and double mineral fertilization (240 kg N ha-1, 300 kg P2O5 ha-1, 300 kg K2O ha-1). In a vegetative season of 2009/2010 the research area had 924, 4 mm of rainfall, which represents an increase of 83, 9% compared to the average value throughout the years before. The monthly average temperature was 9, 9° C which is an increase of 0, 36°C compared to the previous average value. Results show that liming increase soil pH (KCl), while mineral fertilization acidify the soil. Mineral fertilization significantly increased soil available phosphorous and potassium. Significantly lowest wheat grain yield was achieved on control treatment (2.14 t ha-1). Liming significantly increased grain yield (0, 68 t ha-1) in treatment with mineral fertilization, but not significantly (0, 43 t ha-1) without fertilization. Winter wheat grain yield was significantly increased by mineral fertilization (1, 7 t ha-1 fertilization without liming, 2, 38 t ha-1 with liming), while double mineral fertization decreased grain yield (0, 48 t ha-1) comparing to standard fertilization. The mineral fertilization increased straw yield, while liming and doubled mineral fertilization didn't affect it.
