Abstract/Contents: | A study was undertaken to evaluate the effects of IBDU-UF in various ratios of IBDU:ureaform nitrogen, particle sizes, application times, and irrigation rates on Kentucky bluegrass quality measured by clipping yields and color ratings. While the study continues, it was observed in the first year that the delay in response from IBDU was apparent in this test. Earlier spring growth and color were favored by fall-applied IBDU. Plots receiving a single fall application of IBDU in 1972 were severely hit by leafspot in the spring of 1973. In 1973 conditions were about perfect for leafspot and the high nitrogen added to the problem. The finer particle sizes gave faster response than the coarse particle size, indicating faster release of N. No significant difference occurred in growth from the sprayable and granular forms of Uramite. Increases in growth due to more water tended to be greater on IBDU plots than on ureaform plots. |
