| Abstract/Contents: | "Phosphorus is an essential plant nutrient, but primary resources are limited and overfertilization may cause eutrophication of freshwater. Our objectives were to examine temperature effects on (a) optimal P rate for turfgrass establishment, and (b) increasing rates of foliar vs. granular P for early spring growth of established greens. Two trials, both on USGA root zones and replicated in April-May over 2 yr, were conducted in daylight phytotrons at 7, 12 and 17 ?C. Experiment 1 compared 5 P rates from 0 to 0.48 g P m-2 wk-1 for creeping bentgrass establishment on a sand containing 13 mg P kg-1 (Mehlich-3). Results showed no temperature effect on the optimal P rate. Bentgrass coverage and clipping yield increased up to 0.12 and 0.24 g P m-2 wk-1 , corresponding to 6 and 12% of the N input, respectively. The concentration of P in clippings was higher at 7 than at 17 ?C indicating that temperature was more limiting to shoot growth than to P uptake. A higher root/top ratio showed that plants invested more in roots under P deficiency. Experiment 2 was conducted using intact cores from a 4-yr-old creeping bentgrass (Agrostis stolonifera L.) green with a Mehlich-3 P level of 34 mg P kg-1. Results showed increased clipping yields up to 0.18 g P m-2 wk-1 and higher P uptake with granular than with foliar application, but there was no effect on turfgrass color and no interaction with temperature. Low temperatures did not justify higher P applications." |
