| Abstract/Contents: | "Shade is an environmental stress that can potentially have a negative impact on warm-season turfgrasses. Over shading can become problematic and lead to the deterioration of turf quality and tolerance. Additional management practices may be implemented to combat shade stress and retain an acceptable turf quality. Iron, when foliar applied, gives turfgrasses a darker green color and thus, may potentially be a management practice implemented to retain acceptable turf quality under shade. Field research was conducted in 2017 and repeated in 2018 on two warm-season turfgrasses in the southern transition zone to examine the impact of iron fertilization under full-sunlight and shade. Diamond zoysiagrass [Zoysia matrella (L.) Merr} and Tifgrand bermudagrass (Cynodon transvaalensis Burt-Davy × C. dactylon) were grown on a native clayey soil under two light levels (full-sun and 40% continuous shade), and treated with four different levels of foliar applied FeSO4·H2O (Control, 1, 3, and 5 kg ha-1 of Fe). The research was broken down into four independent studies (Diamond zoysiagrass under shade, Diamond zoysiagrass under full-sun, Tifgrand bermudagrass under shade, and Tifgrand bermudagrass under full-sun) and assessed based on visual turfgrass quality (TQ), normalized difference vegetative index (NDVI), shoot chlorophyll content, clipping yield, shoot tissue nutrient concentrations, and ash root biomass. Iron treatment had an overall impact on TQ scores for Diamond zoysiagrass under full-sun and Tifgrand bermudagrass under shade and full-sun. TQ scores of turfgrasses treated with 3 and 5 kg ha-1 of Fe were generally higher 1 and 2 weeks after iron applications than the control and 1 kg ha-1 of Fe level for unshaded turfgrasses. This demonstrates foliar iron fertilization may beneficial to improving visual turfgrass quality under full-sun. Although iron treatments only significantly impacted the TQ scores of shaded turfgrasses for one week, foliar iron fertilization has the potential to improve the visual turfgrass quality." |
