This study was carried out to determine the effects of different irrigation intervals (II) and irrigation levels (IL) on yield, quality and net income values of processing tomato cultivation in a sub-humid climatic zone in 2019. A split-plot randomized complete block design with three replicates was used for the field experiments. The II4-days (A) and 8-days (B) were determined as main-plot factor and different IL were established according to 100% (T1), 80% (T2) and 60% (T3) of the cumulative evaporation occurring in the Class A pan were determined as the sub-plot factor. Seasonal crop evapotranspiration (ET) values varied between 419 and 527 mm. The effects of different irrigation strategies on fruit yield, average fruit weight, brix and water productivity values of processing tomato were significant at the p<0.01 level. The greatest fruit yield was obtained in AT1 treatment with 111.65 t ha-1. The highest water and irrigation water productivity values were obtained from AT2 as 22.4 kg m-3 and 31.4 kg m-3 and the lowest values from BT3 treatment as 16.1 kg m-3 and 26.0 kg m-3 respectively. The yield response factor (ky) was determined as 1.7 for the growing season. The net income values of different treatments ranged from 213.49 to 5557.54 $ ha-1 and the net income increased with the augmentation inthe irrigation water applied. Based on the study results, AT1 treatment was recommended to obtain maximum fruit yield and net income. However, in locations with limited water resources, AT2 treatment which provides a reasonable balance between quality components and water requirements can also be evaluated.
