Abstract :The use of organic wastes in agriculture, forestry and land reclamation has been increasingly identified as an important issue for soil fertility, soil conservation and residue disposal. Using organic wastes in agriculture helps not only to dispose these materials economi­cally, but also reduces negative effects on the envi­ronment. In the present study, composted tobacco waste insert ignore into journalissuearticles values(CTW); combined with farmyard manure insert ignore into journalissuearticles values(FM); at different ratios was applied to Typic Xerofluvent soil, and the influence of these amendments on the yield and nutrient composition of butter head letttuce insert ignore into journalissuearticles values( Lactuca sativa L. var. capitata); were investigated. The experiment was conducted in 18 parcels in a randomized-block design with three replications at the Agriculture Faculty’s Research Farm of Ege University in Menemen plain, in the Western Anatolia Region of Turkey insert ignore into journalissuearticles values(38°58′35.51″-38°58′36.03″N; 27°03′84.56″-27°03′89.81″E);. Organic materials were applied to the soil after composting. The treatments were insert ignore into journalissuearticles values(1); control, insert ignore into journalissuearticles values(2); 12.5 t ha -1 FM + 37.5 t ha -1 CTW, insert ignore into journalissuearticles values(3); 25 t ha -1 FM + 25 t ha -1 CTW, insert ignore into journalissuearticles values(4); 50 t ha -1 FM, insert ignore into journalissuearticles values(5); 50 t ha -1 CTW, and insert ignore into journalissuearticles values(6); 37.5 t ha -1 FM + 12.5 t ha -1 CTW. The maximum yield was obtained during the 1st vegetation period insert ignore into journalissuearticles values(62,7 t ha -1 ); in the 100 % CTW application. On account of the 2nd vegetation period’s coinciding with winter and the coldness of the months December, January and February, there happened a slowdown in the lettuce yield. The highest total yield of lettuce in both vegetation periods insert ignore into journalissuearticles values(102.7 t ha -1 ); was determined in 100% CTW application parcels. The lower lettuce yields were determined in the control parcels. CTW and FM applications raised N, P, K Ca, Mg, Na, Fe, Zn and Mn contents of the lettuce. According to the results obtained, it can be said that CTW can be used in agricultural fields just like FM.
