Sažetak
Yields of field crops in Lika region are low, as affected by soil limitations and cold climate. By soil test in surface layer (0-30 cm dept) amounts of plant available P (AL-method) mainly below 5 mg P2O5/100 g of soil (very low levels) were found. Mean air-temperatures in the 4-month period (May-August: means 1981- 1990) in Gospic and Osijek were 16.3 oC and19.6 oC, respectively. For this reason, growing of short maturity group of maize hybrids (FAO 100 and 200) could be recommended in Lika region. The field experiment with three corn hybrids and four rates of ameliorative P fertilization (monoammonium phosphate) was conducted in spring 2001. Grain yields were increased for 30% and they were as follows: 6.87, 7.89, 7.81, 8.96 and 9.02 t/ha, for the control, 500, 1000, 1500 and 2000 kg P2O5/ha. Mean yields of individual hybrids were as follows: 7.65 (Alpos), 8.02(OsSK247) and 8.65 (OsSK332) t/ha.
