Treatment of 0.5 per cent FeSO4 with 0.05 per cent citric acid significantly increased fruit yield by about two fold and increased significantly active iron, total Fe and S contents of the leaves by about one and a half to three fold over control. It decreased significantly leaf sap pH. These treatments could effectively control the chlorosis as well as fruit yield. Fruit yield was closely associated with the decrease in chlorosis (r = 0.939**). The chlorosis of acid lime grown on loamy sand soils due to high soil pH, lower concentration of active iron, total Fe and S in the chlorotic leaves, S deficiency in soil and frequent use of high HCO3, containing irrigation water could be cured by foliar spray of soluble salts of iron and sulphur.
