| Abstract/Contents: | "Questions have been raised by homeowners and golf course superintendents about the feasibility of fall applied N to enhance fall color and spring greenup of zoysiagrass. Winter hardiness must also be considered if this approach is attempted in the Midwest transition area. In 1989, we initiated a program emphasizing September to November fertilization of 'Meyer' zoysiagrass and FZl-102 zoysiagrass, a fine-textured selection from Florida. Zoysiagrasses received 49 kg N ha-1 urea, 46-0-0 (N-P2O5-K2O) in June (J), June + September (S), J + S + October (O), and J + S + O + November (N). A 2x rate, 98 kg N ha-1, was also applied in September as part of a second J + S + O + N treatment. In addition, one-half of each zoysiagrass plot received an annual application of 49 kg K2O ha-1 potassium chloride, 0-0-60 (N-P2O5-K2O) in September and October for an annual total of 98 kg K2O ha-1. Injury was observed in FZ-102 following winter 1990-91 and was most severe in plots receiving N in J-S2x-O-N compared with J only or J-S. Winter injury as well as weed infestations, quality and color responses, was attributed to total seasonal N, timing of N application, or the combination of N rate and timing. Potassium intensified winter injury, a result which is inconsistent with earlier research reports. Fall N treatments caused no winter injury in Meyer zoysiagrass and small improvements in fall color and spring greenup were noted as N treatments were extended into October and November. However, winter annual weeds proliferated with N applications later than September. Any small benefit in fall color and spring greenup of zoysiagrass with fall fertilization in the Midwest transition area was mitigated by the increasing weed populations." |
