The Effects of Form and Doses of Nitrogen Fertilizer on Grass Quality Performance at the Plant of Fine-Textured Lawns

Abstract

This study was carried out in Igdir University Sehit Bulent Yurtseven Campus in the vegetation period of 2020 to determine the effects of nitrogenous fertilizer sources and doses on the quality of lawn plants in turfgrass areas. 20-10-10 7 SO3, 15-5-20 + 2 CaO + 2 MgO, ammonium sulfate (21% N), urea (46% N) fertilizers with nitrogenous fertilizer sources were applied on the parcels in doses of 0-2-4-6-8 g/m2/month. The effects of fertilizers used after structuring in lawns on plant height, leaf green tone, fresh grass quantity, quality and coating ratios were examined. Festuca rubra 40%, Festuca rubra commutata 30%, Festuca rubra trichopylla 25%, Poa pratensis 5%, which are thin textured from cool climate grass species, were used in the mixture. The trial was established according to the factorial trial pattern in coincidence blocks with three repetitions. As a result of the research, ammonium sulfate and 8 g m-2 doses were found to be more effective when evaluated for grass quality and performance after structuring in thin-textured grass species.
