Abstract :
The aim of this study is to compare effects of composted tobacco waste (CTW) with farmyard manure (FYM) on macro element status of soil and yield of lettuce. This research was held in the experimental fields of Agriculture Faculty’s Research Farm of Ege University in Menemen-Izmir-Turkey in the years of 2005 and 2006. Tobacco wastes gathered from cigarette industry were composted and applied to lettuce (Lactuca sativa L. var. capitata) with manure. No mineral fertilizers or pesticides were applied. The treatments were; (1) control, (2) 12.5 t ha^-1 FYM + 37.5 t ha^-1 CTW, (3) 25 t ha^-1 FYM + 25 t ha^-1 CTW, (4) 50 t ha^-1 FYM, (5) 50 t ha^-1 CTW, (6) 37.5 t ha^-1 FYM + 12.5 t ha^-1 CTW. During the experiment, soil samples were taken three times in two different periods (1st, September 7, 2005; 2nd, November 11, 2005; and 3rd, April 14, 2006). The effects of CTW and FYM on soil nutrients and the yield were investigated. All application rates provided increasing effects on soil when compared with control. Increasing N, P, K contents provided a rise in yield. Maximum lettuce yield was 102.7 t ha^-1 at the plots where 50 t ha^-1 CTW was applied. The results show that CTW can be used as a plant nutrients resource.
