A two-year trial of Kentucky fire-cured tobacco fertilisation with compost from urban organic waste was conducted with three cultivars (Foiano, Riccio beneventano and SKL) on two farms in the province of Benevento (Italy). A commercial compost, produced by Gesenu, was applied each year on the same plots at levels of 10 and 20 t/ha, supplemented or not with 75 kg/ha N, and was compared with a pure mineral fertilisation with 135 kg/ha N. Such levels of compost were chosen more on account of waste recycling aims than on account of Kentucky tobacco needs. In the first year cultivars SLK and Riccio performed better than Foiano with the mineral N supplemented compost treatments. Chemical and visual quality of tobacco was not influenced by the compost or its application level and the range of responses was rather narrow. In the second year the 20 t/ha rate of compost compared well with the whole mineral treatment, with yields higher than the 10 t/ha rate, but was inferior to the latter supplemented by mineral N. Chemical and visual quality was better with the lower level of compost supplemented with mineral N. Cultivar SKL was the best for both yield and quality.
