Poly house experiment was carried out at Zonal Agricultural and Horticultural Research Station (ZAHRS), Navile, Shivamogga during kharif 2016 to study the response of tomato fruit to different sources and levels of calcium. Three sources of calcium [CaCl2, CaNO3 and calcium ammonium nitrate (CAN)] with three levels each (0.20, 0.50 and 0.80%) were applied as a foliar spray in a Complete Randomized Design (CRD) with three replications and ten treatments. The results of experiment indicated that foliar application of calcium through different sources increased the growth and yield of tomato significantly over the control (water spray). Among the treatments, treatment receiving 0.5 per cent CAN as foliar spray was recorded higher growth parameters viz., plant height (94.47cm @ 30DAT and 149.21cm @ 60 DAT), number of branches (16.41 @ 30DAT and 24.47 @ 60 DAT), stem diameter (5.17cm @ 30 DAT) and yield attributes of number of fruits per cluster (10.6), number of fruits per plant (58.67), fruit weight (111.89g), fruit diameter (4.72cm), average fruit yield of 91.98 t ha-1 followed by foliar spray of 0.5 % CAN and CaCl2 @ 0.8 % compared to control. The next best source of calcium for foliar spray found to be CaCl2 @ 0.8 % which shows higher quality and nutrient content of tomato fruit.

Key words: Calcium, Growth parameters, Yield attributes, Tomato, Fruit weight.
