| Abstract/Contents: | "University of California scientists conducted field experiments at Industry Hills Golf Club at Pacific Palms Conference Resort, City of Industry, CA to determine the optimal N fertility rate for southern California putting greens composed of mixed swards of Poa annua and creeping bentgrass. Results from this study show that optimal and deficient annual N fertility rates for Poa annua-creeping bentgrass putting greens in California probably range from 6.0 to 3.0 lb/1000 ft2, respectively. This information is a general guide, keeping in mind that annual N fertility rates may need to be adjusted depending on several factors, such as amount of play, soil type, expectations of turf quality, and green speed, and others. Lower annual N fertility rates resulted in significantly lower visual turfgrass quality and color, clipping yields, recovery from core cultivation, and shoot density. There also was a trend that lower annual N fertility rates resulted in more Rhizoctonia brown patch coverage, while higher annual N fertility rates resulted in more seedhead coverage." |
