This research was held in Agriculture Faculty of Ege University Menemen Investigation and Practise Farmyard.
Tobacco waste gathered from cigarette industry were composted and applied to the soil together with farmyard
manure. lettuce (Lactuca sativa L. var. capitata) was grown as test plant. No mineral fertilizers or pestisides
were applied. The effects of composted tobacco wastes and farmyard manures on soil physical properties and
lettuce yield were investigated. All application rates provided increasing effects on soil’s physical properties at
different percentages. Also, similar effects were determined for lettuce yield. Maximum yield was 102,7 ton ha-1
at the plots where % 100 composted tobacco wastes were applied. The results show that there are positive effects
on all soil properties by the applications of the studied material; ( thus ) and this organic material source
shouldn’t be destroyed. Enviroment is also kept clean.
