| Abstract/Contents: | ""Bulb lawns" or "bulb meadows" include a polyculture of managed turfgrass and springflowering, bulb plants. Bulb plants used for this purpose typically evolved in alpine locations that have compressed growing seasons. Thus, these plants are well suited to emerge from dormancy, provide a spring floral display, and reenter dormancy in the span of a few months in early spring. The short growing season of bulb plants begins before turfgrass initiates spring growth and ends soon after turfgrass reaches optimal growth in early summer. Increased nitrogen in turfgrass systems would be expected to increase the competitiveness of turfgrass with bulb plants and decrease bulb persistence via microbial degradation. Plant growth regulators could be used to reduce turfgrass competitiveness in late spring while bulb plants are storing carbohydrates for the upcoming dormancy season. Few research studies have investigated factors, such as fertility programs or turfgrass species, that influence incorporation of flower bulbs into managed turfgrass systems. The objective of this study is to evaluate the influence of turf species, fertility programs, and bulb-plant species on floral density under management as a bulb lawn. Field trials were conducted at Virginia Tech's Glade Road Research Facility and Turfgrass Research Center in Blacksburg, VA for 2 and 3 years, respectively. Studies were established as randomized complete block designs with a split-plot treatment arrangement. Main plots included a 2 x 5 factorial arrangement of turf species by fertility programs. Subplots included rows of 10 bulbs for each of 7 flower bulb species including Iris histroides 'Katherine Hodgkin', Crocus chrysanthus 'Cream Beauty', Crocus tommasinianus 'Ruby Giant', Muscari azureum 'Grape Hyacinth', Muscari azureum 'Venus', Narcissus ssp. 'Rip Van Winkle', and Narcissus jonquilla 'Baby Moon'. The five fertility programs included no fertility, turfgrass-based nitrogen fertilizer (N), bulb-plant-based phosphorous and potassium fertilizer (PK), integrated fertility that includes nitrogen, phosphorous, and potassium fertilizer (NPK), and NPK plus fluazifop at 105 g ai/ha as a turfgrass growth regulator (NPK+TGR). The two turfgrass species were established over bulbs by laying sod, and these included Lolium arundinaceum and Festuca rubra. The two most abundant flowering bulb species were C. tommasinianus 'Ruby Giant' and N. jonquilla 'Baby Moon' with an average of 32 and 35 blooms per plot, respectively in the first season. The seasonal bloom count of C. tommasinianus 'Ruby Giant' increased 30% by the third growing season while that of Narcissus jonquilla 'Baby Moon' decreased 85% in the same period. F. rubra decreased bloom density of most species when compared to L. arundinaceum. Only three bulb species responded to the fertility program with respect to bloom density and this response was dependent on turfgrass species. These included I. histroides 'Katherine Hodgkin', C. chrysanthus 'Cream Beauty', and N. 'Baby Moon'. In general, bloom density increased in programs that included PK and was the highest in programs that included NPK. Fertility effects were no longer evident at three years after planting. Long-term bloom density appeared to be governed more by bulb species and turfgrass type than by other factors." |
