The aim of this experiment was to compare the influence of fertilizers with different speed of nutrients release on growth-production indicators of turf under non-irrigated conditions. The experiment was carried in warm and dry conditions in area Nitra (Slovak Republic). In the experiment were followed 5 treatments (1. without fertilization, 2. Nitre with dolomite, Superphosphate, Potassium salt, 3. Turf fertilizer Travcerit®, 4. Slow release fertilizer SRF NPK 14-5-14 (+ 4CaO + 4MgO + 7S), 5. Controlled release fertilizer Duslocote® NPK (S) 13-9-18 (+6S)). The highest gain of height reached variant fertilized by fertilizer SRF NPK 14-5-14 (+ 4CaO + 4MgO + 7S). Comparison of the individual treatments for the whole period showed significantly lower average daily gains of height on control treatment compared to fertilizing treatments Nitre with dolomite, Superphosphate, Potassium salt, SRF NPK 14-5-14 (+ 4CaO + 4MgO + 7S) and Duslocote® NPK (S) 13-9-18 (+6S). During the reported period the highest gain of weight reached treatment by application fertilizer Duslocote® NPK (S) 13-9-18 (+ 6S). Comparison of the individual treatments for the whole period, were found significantly lower average daily production of phytomass on control treatment in comparison with fertilization turfs by Travcerit® and Duslocote® NPK (S) 13-9-18 (+6S).
