Response of maize to phosphorus fertilization in Posavina Canton

The field trial of phosphorus fertilization was conducted on calcareousalluvial alkaline soil of Posavina Canton (Bosnia and Herzegovina) in spring 2011: a) unfertilized ; b) basic fertilization = 75 P2O5 kg ha-1 ; c) a + 200 P2O5 kg ha-1 ; d) a + 400 P2O5 kg ha-1 ; e) a + 800 P2O5 kg ha-1 ; f)a +1200 P2O5 kg ha-1.The experiment was conducted in four replicates (basic plot 60 m2). In this study maize (hybrid OsSK596) response (the 2011 growing season) was shown. Mean yield of maize grain of the fertilization treatments (b-e) in level of 11.03 t ha-1 was relative low due to less favorable weather conditions. Maize yield increases were 8% and 53% by f:b comparison and f:a comparison, respectively.
