Fifty different winter wheat genotypes grown in vegetation pots were tested on pseudogley soil having an extremely acid reaction (pH (KCl) ˂ 4.5) and a mobile Al content of above 10 mg 100 g -1 soil. The test soil was low in humus, phosphorus and potassium. In order to increase soil fertility and crop productivity, the experiment involved the use of different treatments with NPK, increased P amounts and lime fertilizer, and their comparison with the control (neutral reaction soil – Humogley). Results showed the highest tolerance to low soil pH and high mobile Al content in winter wheat cultivars Ornil, Roane, Rapsodija and Nevesinjka. All genotypes, most notably Ornil, Roane and NS Rana 5, exhibited a very good response to phosphorus and lime fertilizers.
