Influence of foliar application of nutrients on growth, yield and quality of potato (Solanum tuberosum L.) under hill zone of Karnataka

A field experiment was conducted to know the “Influence of foliar application of nutrients on growth, yield and quality of potato (Solanum tuberosum L.)” at College of Horticulture, Mudigere during 2017-18. The results revealed that foliar applications of micronutrient mixture @ 5g/lit recorded significantly higher plant height (38.67 cm), number of leaves (108.20), number of stem (5.27), plant spread (47.57 cm), Leaf area index (3.34), fresh weight of leaf (30.99 g), fresh weight of stem (73.47 g), dry weight of leaf (7.06 g), dry weight of stem (11.54 g), dry weight of root (4.87 g), total dry matter production (23.47 g/plant) with respect to growth parameters. Yield and quality parameters viz. similar treatment recorded maximum number of tubers per plant (2.89), number of tubers per plot (86.70), yield per hectare (20.80 t/ha), tuber volume (124.98 cc), tuber weight (98.65 g),tuber circumference (14.90 cm) and total sugars (2.41%) as compared to control.
