This research project was done to study the influence of rate and ratio of sulphate and chloride ions on: (1) fresh weight and dry matter of leaf and stem of tomato; (2) tomato yield; (3) fruit size; (4) vitamin C content; (5) pH of fruit juice; (6) the content of N, P, K, Ca, Mg, S and Cl by tomato after harvesting. The results of the experiment showed no significant difference on fresh and dry matter of plant; vitamin C content; pH of fruit juice; fruit size and N, P, Ca and Mg content in fruit and tomato plant grown in Pakchong soil when applied with sulphate and chloride in different rates. The application of chloride increased yield and chloride content in fruit, but the choloride content in tomato plant decreased with the higher rates. The maximum content of K was increased when applied with chloride up to the rate of 0.6 gm C1 per pot. The percentage of S0=4-S in tomato plant was also increased when applied with SO=4-S in soil, but no significant difference occurred in tomato yield; K content in fruit and tomato plant and SO=4-S content of fruit.
