Abstract/Contents:"Frequent irrigation is an often used practice to prevent creeping bentgrass (Agrostis stolonifera L.) putting greens from drought stress in the summertime. The objective of this study was to determine the effects of short-term excessive irrigation on turf quality, chlorophyll concentration, and root carbohydrate status of creeping bentgrass sand and soil greens. Irrigation treatments were given to both sand and soil plots at 100% of daily evapotranspiration (ET) replacement (100% ET, control), 200% of daily ET replacement (200% ET), and 300% of daily ET replacement (300% ET) for 4 to 6 d in June and July of 2005 and 2006. The treatments in July had more negative effects on both the sand and soil greens compared to those in June. The 200% and 300% ET decreased turf quality in both greens. Chlorophyll concentration was reduced by 14% under 300% ET in the sand green, and was reduced by 12.4% and 16.0% under 200% ET and 300% ET in the soil green, respectively. The effect of 300% ET decreased shoot dry weight to 10.7% in the sand green. Root fructan concentration was reduced by 21% under 300% ET in the soil green. The decreased carbohydrate reserves under excess irrigation may be an important factor contributing to the decline in creeping bentgrass soil green in warmer weather. The results suggest that proper irrigation scheduling and avoiding short-term excessive irrigation in the summertime benefits turf quality by maintaining adequate chlorophyll and carbohydrate levels."
