Abstract/Contents:Research was conducted to evaluate two plant biostimulants and iron effects on the rooting response of 'Penncross' creeping bentgrass (Agrostis palustris). Studies were conducted in both a field and greenhouse environment. Field evaluation was conducted at the John Seaton Anderson Turfgrass Research Facility located near Mead, Nebraska. Greenhouse research was located at the Horticultural Greenhouse Research ring located on the UNL campus. Both locations investigated the following treatments: 1. LP4-91 qpplied at 0.4 fl. oz.(12.0 ml)/ 1000 sq. ft. 2. LP4-91 + LESCO Chelated Iron Plus applied at 0.4 fl. oz.(12.0 ml)/1000 sq. ft. and 4 fl. oz./1000 sq. ft. respectively. 3. MFX-GTZ applied at 0.4 fl. oz.(12.0 ml)/1000 sq. ft. 4. MFX-GTZ + LESCO Chelated Iron Plus applied at 0.4 fl. oz.(12.0 ml)/1000 sq. ft., respectively. 5. LESCO Chelated Iron Plus applied at 4 fl. oz./1000 sq. ft. 6. Untreated Control. Results of root strength evaluations are shown in Table 1. Data means are shown in Table 2. Due to lack of significant treatment differences, these means are shown for illustrative purposes only, and numerical differences should be ignored. Based on field and greenhouse trials, the following points concerning investigated treatments can be made: 1. Biostimulants applied alone or in combination with iron exhibited greater root strength than untreated plots. 2. Iron inhibited root strength. 3. Applied treatments had no effect on root weights. 4. Based on 1 and 3, the increase in root strength cannot be attributed to an increase in root mass. The increase in root strength may be attributed to a change in root morphology not evaluated in this study. 5. In a greenhouse trial, applied treatments did not effect root growth rate or penetration. 6. Positive effects on root strength indicate that products investigated may be beneficial in many turf management situations.
