| Abstract/Contents: | "Little research has been conducted to determine the influence of fertilizer sources and rates on zoysiagrass (Zoysia japonica Steud.) establishment. Our objectives were to determine the influence of slow-release N sources, water-soluble N from urea, and N. P. and K combinations on rate of zoysiagrass establishment. Prior to field planting of zoysiagrass plugs, N rates of 98. 196, and 392 kg ha-1 from ureaformaldehyde (UF, 38N-0P-0K), isobutylidine diurea (IBDU, 31N-0P-0K, and a composted sewage sludge (1.0N-0.9P-0.2K) were incorporated into a soil with existing high P (193 kg ha-2) and intermediate K levels (86 kg ha-1). In a separate study nitrogen from urea (46N-0P-0K, 195 kg ha-1), P from treble supperphosphate (0N-19P-0K, 126 kg ha-1) and K from muriate of potash (0N-0P-32K), 103 kg ha-1) also were incorporated before planting. Five months after planting, none of the slow-release N sources or N-P-K combinations had enhanced coverage of the zoysiagrass. No additional fertilizer was applied in the 2nd year. Although statistically significant differences were found among treatments by the end of the 2nd growing season, the actual increases in zoysiagrass coverage provided by the fertilizers were no greater than 5% more than the unfertilized zoysiagrass. In a 3rd study, N (49 kg ha-1) from urea, applied as a topdressing either once, four or seven times annually, resulted in a negative linear [coverage = 63.8 - 0.02 (kg N/ha per year), r2 = 0.57] response in zoysiagrass coverage the intital year, but not in the 2nd year. Nitrogen from urea (49 kg ha-1) applied biomonthly or monthly the 2nd year had a greater beneficial effect on zoysiagrass growth than topdressing or preplant incorporation of N the initial year." |
