Effect of Fertilizer Rates and Placement Practices on Yield of Burley Tobacco

Management of fertilizer practices in production of burley tobacco is very important in control of manganese (Mn) toxicity of the crop. In addition to the use of agricultural limestone, the use of fertilizers in the appropriate amounts, the appropriate kinds, and in the appropriate manner can strongly influence acidity in the rooting zone during the growth of burley. Studies of these effects have made up a major thrust of the University of Kentucky\u27s research programs on fertility of burley, and have largely been conducted by J.L. Sims and his students during the past 15 years
