The effects of different combination of combined fertilizer doses on some turfgrass performances of turf mixture

摘要

This study was conducted to determine the effects of different combinations of combined fertilizer dose applications on the turfgrass characteristics of a turf mixture in the ecological conditions of Sakarya/Pamukova in Turkey, between the years of 2013-2015. The research was conducted in the randomized block design with four replications. A cool season turf mixture consisting of 40% Lolium perenne L., cv. Integra, 25% Festuca rubra rubra L., cv. Eugene, 20% Festuca rubra commutata Gaud., cv. Survivor and 15% Poa pratensis L., cv. Evora was used as the material of the study. Such is a widely used mixture in the region. Nine different combination of NPK fertilizer doses (0-0-0, 5-2.5-2.5, 10-5-5, 15-7.5-7.5, 20-10-10, 25-12.5-12.5, 30-15-15, 35-17.5-17.5 and 40-20-20 g m -2 respectively) were tested. In this research; turf cover, weed invasion, uniformity, turf texture, color and turf quality were determined. At the end of the study, the most promising data were taken from the 30-15-15 g m -2 fertilizer dose compared to control.
