| Abstract/Contents: | Study to determine the effect of the application of fertilizer and fertilizer plus various herbicides on the recovery of dormant Kentucky bluegrass turf after the drought of 1988. Plots were 25 sq. ft. This study was located on a stand of nonirrigated Ram-I Kentucky bluegrass. The soil on the site is a Nicollet (fine-loamy, mixed mesic, Aquic Hapludoll) with Pendimethalin, Dacthal, Trimec, and Pendimethalin + Trimec. A table provides rate of application of the treatments. Treatments were applied on July 8, 1988, over the turf plot area which had been completely dormant for seven weeks. It was 95F and sunny on the day of application and the treatments were not watered in. Daytime temperatures remained in the mid 90s for one week following treatment. Treatments were applied in the equivalent of 3 gal H2O/1000 ft2. One week after treatment the plot area was irrigated to bring the Kentucky bluegrass out of dormancy and to determine treatment effects. The plot area was monitored for treatment differences every few days until the Kentucky bluegrass had completely recovered from summer dormancy. There were no visible treatments differences observed at any time during the recovery period with the exception of a slight greening of turf that was treated with nitrogen fertilizer. This study suggests that the application of fertilizer and fertilizer in combination with various herbicides to dormant Kentucky bluegrass does not have a detrimental effect on the recovery of the turf from summer dormancy. An evaluation of positive effects of these dormancy treatments will require futher study. Although little response was observed in treated plots in this study, work in an adjacent area did demonstrate increased recovery on treated areas. If the drought continues, more work will be conducted on this subject during 1989. |
