Abstract/Contents: | "Turfgrass is typically managed through inputs such as fertilizations to produce a healthy, dense turfgrass stand, however, monocultures provide limited habitat and floral resources for pollinators. Adjustments to fertilization practices could further promote floral production and long-term persistence of common lawn weeds as a pollinator resource, but little is known about the influence of fertility on the competition between weeds and warm-season turfgrass species. Therefore, the objective of our research was to study the impact of fertility on perennial weed growth and floral production in hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. traansvalensis Burtt-Davy] and centipedegrass [Eremochloa ophiuroides(Munro) Hack.]. Research was conducted in Athens, GA during the summer of 2022 and 2023. White clover (Trifolium repens L.) and Virginia buttonweed (Diodia virginiana L.) were transplanted into 'IronCutter' hybrid bermudagrass maintained at 3.8 cm and 'Santee' centipedegrass maintained at 6.4 cm. Four fertility treatments were evaluated within each turfgrass species: [0g, 12 kg, 24 kg, and 48 kg N ha-1 for hybrid bermudagrass and 0g, 6kg, 12kg, and 24kg N ha-1 for centipedegrass]. Treatments were arranged in a randomized complete block design with four replications. Granular fertilizer (18-12-6) was applied by hand every four weeks. Weed lateral spread and floral count data were recorded weekly over three months. Preliminary results show that increasing levels of fertility decreased lateral weed spread and floral production in hybrid bermudagrass but increased lateral weed spread and floral production in centipedegrass. Each weed species shows potential as a floral resource for pollinators; however, turfgrass competition in response to fertility varies with respect to species and fertility rate. Utilization of low fertility inputs would hinder bermudagrass growth, which would encourage weed spread and floral production. Centipedegrass is a low input species, so exorbitant amounts of fertility only enhance weed competition and further weed growth." |
