Abstract	A field experiment was conducted at the Research Site of Varamin Agricultural Research Center, Varamin, Iran on sandy loam soils to study the response of tomato (Lycopersicon esculentum) to different tillage methods during 2007 and 2008. Tillage treatments in the study included were conventional tillage (CT; moldboard plowing + two passes of disk harrowing), minimum tillage (MT; one pass of disk harrowing) and no-tillage (NT). Crop yield, yield components (plant population density, PPD; number of fruits per plant, NFPP; fruit weight, FW; fruit length, FL; fruit diameter, FD) and a fruit quality parameter (total soluble solids, TSS) were determined for all treatments. Results indicated that tillage methods significantly (P 0.05) influenced crop yield, yield components and TSS. Results also showed that PPD and NFPP are the most important yield components explaining crop yield difference under different tillage methods. The maximum PPD (10025 plants ha-1), NFPP (19.1) and as a result crop yield (12.2 t ha-1) were observed with CT, while maximum values of FW (71.2 g), FL (70.0 mm), FD (59.2 mm) and TSS (7.27%) were noted NT plots. On the other hand, minimum PPD (5117 plants ha-1), NFPP (10.2) and hence crop yield (3.70 t ha-1) were obtained with NT, while the minimum values of FW (63.6 g), FL (61.0 mm), FD (53.6 mm) and TSS (5.81%) were noted in case of CT treatment. Therefore, one pass of moldboard plow followed by two passes of disk harrow was found to be more appropriate and profitable tillage method in improving crop yield of tomato in the arid lands of Iran.
