Sažetak
The field experiment of liming (0 and 10 t ha-1 of powdered hydrated lime) and phosphorus (P) fertilization (monoammonium phosphate or MAP: 12% N + 52% P2O5) started in autumn 2008 on acid soil (pH in 1n KCl: 4.28) of Lijevce polje region (Laktasi municipality, Bosnia and Herzegovina). Three doses of P (0, 500, 1000 and 1500 kg P2O5 ha-1) on the conventional fertilization (160 N + 75 P2O5 + 75 K2O kg ha- 1) were applied in four replicates (basic plots of liming and P fertilization 640 m2 and 40 m2, respectively). The conventional fertilization was applied in the next years of the experiment. Soil of the experiment was low supplied with plant available P and adequate supplied with potassium (AL-method: 2.9 mg P2O5 and 23.4 mg K2O in 100 g of soil). Maize was grown in monoculture from 2009 to 2013. Average grain yield of maize was considerable different among the years, ranging from 2.06 to 9.38 t ha-1. Under less favorable weather conditions (drought and high temperature stress) in the 2011, 2012 and 2013, yields were considerably lower (mean 4.28 t ha-1) than in the remaining two years (mean 9.20 t ha-1). In general, liming effects on maize yields were stronger than P effects with considerable impacts of weather conditions. Affected by liming, yields were increased for 39%, 18%, 47%, 25% and 158%, for 2009, 2010, 2011, 2012 and 2013, respectively. However, P effects ranged, depending on the year, from non-significant differences (2012) to 32% (2013).
