A of fertilizer is an essential part of a well-planned program of orchard management for the production of pec.ans on the soils of the Southeast. Fertilizers, for the most part, are applied in early spring just before or at the time growth begins. Blackmon and Ruprecht (1) 3 obtained the highest yields on Bladen fine sandy loam soil when the fertilizers were applied in three or four different applications during the year. Later, Blackmon and Barnette (a) showed that summer applications of nitrogen fertilizers increases the yield of pecans over that produced with cover crops. Skinner, et al. (4) found that the time of applying fertilizers pecan orchards should vary according to the source of materials, climatic conditions, and general orchard practice. Their experimental evidence showed that plant food materials are most quickly assimilated during the period of rapid growth in early spring, but that increased yields resulted when additional light applications were made in May or June on deep sandy soils and in orchards where weeds or other plants were competing with the trees for nutrients. It is the purpose of this report to present results of an experiment designed to determine the effects of fertilizers applied at different times during the growing season on tree growth, yield, and quality of pecans.
