Field trail was carried out at the farm unit, College of Agriculture, Hassan Karnataka during the year 2015 to study the effect of foliar application of calcium metalosate on growth, yield and quality parameters of potato. The experiment consisted of 7 treatments viz., T1: Control, T2: Calcium metalosate @ 1 ml/l, T3: Calcium metalosate @ 2 ml/l, T4: Calcium metalosate @ 3 ml/l, T5: Calcium metalosate @ 4 ml/l, T6: Calmagni @ 2 g/l and T7: Samras (amino acid mixture) @ 2 ml. The experiment was laid out in randomized complete block design and replicated thrice. Application of calcium metalosate at different concentration had significant influence on productivity of potato. At harvest, application of calcium metalosate @ 4 ml/l (T5) recorded significantly higher plant height (66.57 cm), more number of leaves (15.33), number of shoots (3.51) at 60 DAP, total dry matter production (52.13 g plant-1), less number of days to 50 % flowering (60 days), number of tubers (6.53 g plant-1), yield (263.29 g plant-1) and total yield (22.54 t ha-1) as compared to control (T1) which was on par with calcium metalosate @ 3 ml/l (T4). Same treatment significantly reduced the late blight severity at 60 DAP (19.10 %) and weight reduction 30 days after harvest (10.10 %).
