Abstract

Data are presented here on sugar yields obtained with a ratoon crop growing on a heavy-claypan soil subjected to different tillage treatments some 28 months prior to the harvesting date. In a previous harvest—that of the original plant crop 14 months following treatments—significantly greater differences were measured favoring the plots which received half of the fertilizer on the subsoil over those receiving all the fertilizer on the topsoil. However, the data herein reported for the following ratoon crop indicate no residual effect from the original subsoil fertilization which could be measured in terms of sugar yields.
