Effect of Alginite and Inorganic Fertilizers on Selected Growth-production Parameters of Turf

Anotace: The four-year-old turf experiment was carried out in the Demonstration and Research Base of the Institute of Plant Production of the Slovak University of Agriculture in Nitra (Slovak Republic). There were followed 4 treatments: 1. without application alginite and inorganic fertilizers (“control”), 2. alginite, 3. inorganic fertilizers (“NPK”), 4. alginite and inorganic fertilizers (“alginite + NPK”). There were evaluated the total height and total production of dry above-ground phytomass in the turf experiment. Turf in control and Alginite treatments were significantly lower than turf with NPK and alginite + NPK through the evaluation period. An overall comparison of the years 2015–2018 showed that significantly (p = 0.00) the highest total turf height achieved by turfs after the application alginite + NPK (538.5 mm) than turfs fertilized NPK (497.3 mm), with the application of alginite (290.9 mm) and control (280.3 mm). The significantly (p = 0.00) lowest production of dry aboveground phytomass was reached by the control (174.5 g.m-2) and the turf with alginite application (201.5 g.m-2) in comparison with NPK (321.8 g.m-2) and alginite + NPK (389.9 g.m-2) treatments in 2015–2018.
