Abstract
This study was conducted to evaluate effects of two slow release nitrogen (N) fertilizers (SRF) blending isobutylidene diurea (IBDU) or methylene urea (MU) on growth, quality and N uptake of creeping bentgrass. Treatments were designed as follow; non-fertilizer (NF), control fertilizer (CF), SRF-1 (IBDU 10%, MU 23%), and SRF-2 (MU 33%). As applied SRF, visual quality, shoot length, clipping yield, top-root (T/R) ratio and N uptake of creeping bentgrass was increased than that of CF. Amount of N uptake was positively correlated to visual quality, shoot length, total chlorophyll content, clipping yield, and dry weight of shoot and root (
