An experiment was conducted at Zonal Agricultural and Horticultural Research Station (ZAHRS), Navile, Shivamogga during kharif 2016 under naturally ventilated poly house condition in order to know the effect of foliar nutrition of different sources and levels of calcium on growth and yield of tomato (Lycopersicum esculantum). Three sources of calcium (CaCl2, CaNO3 and calcium ammonium nitrate) 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. Results of the experiment indicated that foliar application of tomato crop with different calcium sources increased the nutrient content and uptake by tomato fruit and leaves significantly over the control. However foliar spray of 0.5 per cent CAN resulted in increase in nutrient content viz., pH (4.19), N (1.96 %), K (4.96 %), Ca (0.84 %), Mg (0.43 %) in fruit and in leaves at different stages (vegetative, flowering & fruiting stage). Nutrient uptake by the tomato fruit recorded significantly higher N, K, Ca, Mg (166.97, 438.70, 77.26, 39.55 kg ha-1) content due to foliar application of 0.5 per cent CAN compared to other sources of Ca and control. Thus this experiment conclusively proves that nutrient supplementation with Ca (0.5% CAN) as foliar spray will enhance the quality of tomato fruit due to increased nutritional status.
