The Effects of Different Nitrogenous Fertilizer Sources and Doses on Football Field Grass Performances

Abstract

Nitrogen has a huge importance in terms of ensuring the development of roots and shoots in grass and giving plants resistance to diseases. Using the right fertilizer in appropriate doses in the maintenance and repair of football fields is one of the maintenance procedures that increase grass performance. This study was carried out on the football field grass established at Iğdır University Sehit Bulent Yurtseven Campus during the 2020 vegetation period in Iğdır conditions. The research aimed to determine the most suitable fertilizer type and dose for football fields. The experiment was designed with three replications according to the randomized blocks factorial trial design. In the application area, a grass mixture of Festuca arundinacea Jaguar 4G 30%, Festuca arundinacea Apache 20%, Festuca arundinacea Arid III 20%, Lolium perenne Belida 15% and Lolium perenne Esquire 15% was used. As nitrogenous fertilizer sources, 20-10-10 7SO3, 15-5-20 + 2 CaO + MgO, ammonium sulfate (21% N) and urea (46% N) fertilizers are 0, 2, 4, 6 and 8 g/m 2/ It was administered in monthly doses. In the study, the effects of nitrogen use in fertilization on grass plant height, quality, fresh grass amount, and leaf green tone and leaf texture were observed. As a result of the study, it was determined that the most ideal fertilizer type and dose were 6 and 8 g m-2 doses of urea and ammonium sulfate fertilizers.
