This study was carried out in order to determine the effects of different emitter spaces and water stress on total fruits yield (TFY); yield suitable for processing (PFY) and paste output (PO) of processing tomato (Lycopersicon esculentum Mill cv. Shasta) and some quality characteristics (mean fruit weight-MFW, fruit diameter-FD, penetration value of fruit-PV, pH, total soluble solids-TSS and ascorbic acid-AA contents) under ecological conditions of Konya Plain in 2004 and 2005 years. The randomized split block experimental design with three replications was applied in the study. Drip irrigation laterals were arranged in such a way that every row had one lateral. Emitter spacing of 25, 50 and 75 cm (A, B and C respectively) were the main treatments while four levels of water supply irrigation at 7 days intervals with water amount enough to fill the soil depth of 0-60 cm till field capacity ($I_1$), and 25, 50 and 75% decreased water supply levels ($I_2$, $I_3$ and $I_4$) were applied as sub treatments of the experiment. According to results of the main treatments for two years showed that the highest total fruits yield (51.75-52.43 t $ha^{-1}$), as well as yield suitable for processing (47.23- 49.33 t $ha^{-1}$) were obtained from A treatment (p<0.01). On the other hand, the highest TFY, PFY and PO of the sub treatments were obtained from $I_1$ application. MFW, FD and TSS were significantly affected from the sub treatments (p<0.05). High stress resulted in the highest soluble solids. Total irrigation water amount and water consumptive use of the treatment A were determined as 250-376 mm and 414-425 mm, in 2004-2005. Total irrigation water amount and water consumptive use of I1 treatments were 426-587 mm and 520-623 mm for two years, respectively.
