Effects of 2 Slow-Release Fertilizers on the Propagation and Subsequent Growth of 3 Woody Plants
Three woody plants were propagated from cuttings with four levels each of slow-release 27 N-5.2P-0.OK (27-12-0) and 0N-0P-38.2K (0-0-46) fertilizer in factorial combination. Slow-release fertilizer added during propagation had little effect on rooting of cuttings, however, after rooting and before transplanting into larger containers in the spring, the 27-12-0 stimulated both root and top growth of all species. All growth parameters measured for all species grown in 3.8 1 (#1) containers were significantly increased after one growing season when treated with a combination of slow-release N and P during propagation or following transplanting.
