In order to evaluate the effect of soil pH , phosphorous and potassium element on growth and yield of tomato plant (Lycopersicom esculentum c.v Calji) in soil culturing, was conducted an experiment as factorial arrangement in completely randomized design with three replications. The first factor was including different soil pHs (6, 7, 8) and the second factor was consisting phosphorous and potassium fertilizers(0, 40 and 80 mg P Kg-1 soil) in the form triple super phosphate, Potassium nitrate was used as. . To provide nitrogen, 200 mgKg-1 urea was equally used to the plants. Then the traits of flower number, fruit number, plant yield, vitamin C, and TSS and chlorophyll index were recorded. . Factors, the number of flowers. Total fruit and plant chlorophyll were recorded Experimental results showed that the highest number of goals in the levels of potassium and phosphorus were observed at 6 and Edge and the least number of flowers in the levels of potassium and phosphorus were observed Edge 8. 40 mg kg potassium and phosphorus in the soil was observed at pH 6 in Chlorophyll lowest levels of 40 mg per kg of soil phosphorus and potassium was observed.
