The yield data from a series of fire-cured variety × fertilizer trials in Malawi are presented. Variety was not important in determining total yields though it was in influencing the distribution of grades. Fertilizer had a large effect upon yields, particularly upon the Cutter and Leaf grades, but environment had by far the greatest influence. High levels of applied fertilizer could not be relied upon to replenish a depleted soil so that it produced yields comparable to those from a soil with well-maintained fertility. Application of fertilizer produced a beneficial change in the grade distribution within the crop.
