Abstract/Contents: | "'L-93' creeping bentgrass was examined at a fairway mowing heights (3/8 inch) to compare variation in irrigation frequency requirements and to develope Crop Water Stress Index (CWSI) values. The CWSI is a technique that uses the measurement of canopy surface temperature and air temperature to infer water stress status and whether irrigation is needed. Treatments included irrigation at four intervals: 1) three times per week (Monday, Wednesday, Friday); 2) two times per week (Monday and Friday); 3) once per week (Friday); and 4) biweekly (every other Monday). This field project was conducted in a fully automated, mobile rainout shelter (35' x 60') at Rutgers University Horticulture Farm II, allowing for strict control of irrigation frequency and amount. CWSI values were calculated using air and surface canopy temperature measurements and is expressed as a ratio of actual canopy and air temperature difference to the maximum canopy and air temperature difference of a plant. Results demonstrate that CWSI values below 0.40 result in acceptable turf quality. Additionally, irrigating at 100% ET, three times a week may not be necessary to sustain plant growth and physiological processes, and that this can be depended on time of year. Generally, irrigating once or twice a week and replacing 100% of ET was adequate to maintain acceptable turf quality during summer months. Watering at the 14-day interval was not sufficient to maintain acceptable turf quality." |
