Tomato (Solanum lycopersicum) is among the most important vegetables all around the world. Blossom end rot is a disorder that is caused by deficiency of calcium that deficiency gradually leads to the necrosis of tissues and ultimately stopped the plant growth. In tomato, fruit appears as sunken, dry and decaying areas at the blossom-end of the fruit. This Study was conducted to find out the impact of foliar application of various concentrations of Calcium Chloride (CaCl2) on tomato hybrid “Saandal F1”. Different concentrations of Calcium Chloride (CaCl2) were prepared with distilled water (CaCl2 0.5g L-1 of water), (CaCl2 0.75g L-1 of water) and (CaCl21.0g L-1 of water) and sprayed three times during plant growth by 20 days interval with a sprayer. The Exogenous application of Calcium chloride (CaCl2) showed a significant effect on plant height, number of fruits/plant, flower clusters/plant, Fruit weight, Fruit TSS, fruit set percentage, fruit pH, number of diseased fruits and blossom end rot incidence. Calcium chloride (CaCl2) at concentration pf 1.0g L-1 of water showed significant results. Hence, tomato growers can adopt this simple management tool for improving quality and yield of tomato in the world.
