Fertidyne (beta-amulose tri-iodide) was tested on many soils planted to sugarcane, tobacco, and pineapples to determine whether this material could increase yields. The results obtained were as follows: 1. Yields of sugar per acre, in general, were not significantly increased when Fertidyne was used with fertilizer as compared to yields under fertilizer alone. 2. Fertidyne alone did not increase yields of sugar significantly over the check treatment where nothing was added to the soil. 3. Fertidyne alone did not increase yields of sugar per acre when compared to the addition of fertilizer alone to the soil. 4. Yields of sugar per acre tended to be higher with Fertidyne for the plant crop than for the ratoons. 5. Neither tobacco yields nor quality were increased or improved when Fertidyne was used. 6. Pineapple yields, in general, did not increase when Fertidyne was applied, with or without fertilizer.
