Sažetak
Phosphorus (P) deficiency is limiting factor of field crops yields on some soils in area of Sava lowland in Croatia and Bosnia. It is mainly found on pseudoglay and similar soil types situating at northwestern part of Pannonian region and in mountain region of the country. Aim of this study was survey of four field trials results with increased P fertilization. The trials were conducted in spring 2001 (the trials A, B and D) and 1990 (the trial C) in four replicates. Two identical field experiments (A and B) were conducted on acid hydromorphic soils of Sava lowland area (Brod-Posavina County). Low P supplies were found by previous soil test. Different fertilization treatments included also two P levels (MAP: 12% N + 52% P2O5) as follows: a) control (ordinary fertilization) ; b) a + 750 kg P2O5/ha ; and c) a + 1500 kg P2O5/ha.). Experimental plot of fertilization measured 64 m2. In each plot of fertilization were grown three maize hybrids (OsSK444, OsSK552 and Bc5982). Mean maize yields were 8.01 and 8.56 t/ha, for the experiment A and B, respectively. Significant influences of applied fertilization on grain yields were found only on the trial A (grain yields in t/ha): 7.63 (a), 7.94 (b), and 8.97** (c). Effects of ameliorative fertilization (up to 2550 kg either P2O5 or K2O/ha) were also found on Crnac polje near Nova Gradiska (the trial C). By using the highest rate of P fertilizers maize yields were increased for 41% in comparison with the control (3.81 t/ha).
