| Abstract/Contents: | "Water is one of the major growing factors that affect plant growth and survival under drought stress. Water deficits induce deleterious effects such as plant growth and photosynthesis reduction. Kentucky bluegrass (Poa pratensis) is one of the most widely used cool-season grasses and require high water demand. Potassium (K) enhances plant tolerance to drought by controlling stomata and osmosis. The objective of the study is to evaluate Kentucky bluegrass three cultivars which are 'Award', 'Beyond', and 'Midnight' treated by different potassium fertilization rates under non-irrigation condition. The K applications were made with the rate of 0, 10, 20, and 40 g m-2. The result indicated that the most drought tolerant cultivar is 'Award' and the rate of 40 g K2O m-2 had positive effects such as shoot growth and maintaining soil water content under drought condition. When soil water content is less than 10.2% or precipitation is more than 10.5 mm, there are no positive effects of K application. Under the drought environment, Kentucky bluegrass 'Award' and K application would be positive effects when artificial irrigation is limited." |
