EFFECT OF SALICYLIC ACID AND POTASSIUM SULPHATE ON GROWTH AND YIELD GRAPES CV. 2A CLONE

A field experiment was conducted during the year of 2023-2024 at Main Horticulture Research and Extension Centre (MHREC) under the University of Horticultural Sciences, Bagalkot in order to evaluate the effect of salicylic acid and potassium sulphate on growth, yield and quality of grapes cv.2A clone.The experiment was laid out in randomized block design with three replication and nine treatments.The results revealed that, T 8 treatment (salicylic acid 4mM + potassium sulphate 0.75 %) recorded the highest internodal length and girth of fruiting shoots (4.44 and 5.28 cm and 5.52 and 7.80 mm respectively), Leaf chlorophyll (26.77 and 36.41SPADvalue), leaf area(73.53 and 103.10 cm 2 ), number of bunches per vine (45.41), number of berries per bunch (204.50),bunch length (20.17cm), bunch width (17.55 cm), bunch weight (620.30g), yield (21.60 kg/vine) and yield (39.61 t/ha).
