| Abstract/Contents: | "Environmental concerns have led to the implementation of fertilizer ban or "blackout" period during the summer months in Florida. Response of turfgrass to lack of N fertilization during the summer months needs to be investigated. An experiment was conducted from January until December 2021 and 2022 at the University of Florida's Fort Lauderdale Research and Education Center (FLREC) and West Florida Research and Education Center (WFREC) to investigate effect of different fertilizer programs on 'Empire' zoysiagrass (Zoysia japonica Steud.) mowed at 5 cm height and watered at 70% evapotranspiration to prevent drought stress. Plots received either: 0 g N m-2 year-1 (control); 10 g N m-2 year-1 through urea (46-0-0) or a 3:1:2 N:P:K blended fertilizer (21-7-14); 14 g N m-2 year-1 using two different formulations of 2:0:1 N:P:K fertilizers applied monthly outside the blackout period; 12 g N m-2 year-1 using two different formulations of 2:0:1 N:P:K fertilizers applied monthly outside the blackout period. Blackout period went from June until September at WFREC and from June until October at FLREC. Plots were rated monthly for visual quality on a scale from 1 to 9 (1=worst; 9= best), Normalized difference vegetation index (NDVI) and percent green cover and Dark Green Color Index (DGCI) by Digital Image Analysis (DIA). While no differences among treatments were detected at WFREC, all treatments performed better than control at FLREC, and fertilized treatments achieved sufficient turfgrass quality from April until December. Lowest percent green cover and DGCI where detected in control plots during the summer months, suggesting that fertilizing outside blackout period can help zoysiagrass sustain sufficient quality even if not fertilized during the growing season." |
