Abstract: In the present study on growth and yield of grapes cv. Sharad Seedless different sources and methods of potassium were applied. The experiment was laid out with eight treatments replicated four times in Completely Randomized Block Design at the ICAR-Indian Institute of Horticultural Research, Bengaluru in 2016-17. Three different sources of potassium fertilizers viz., sulphate of potash (SOP), potassium nitrate (KNO3) and 19: 19: 19 and two methods of application viz., soil application and fertigation were applied to Grape vines. Among the treatments, highest mean pruned biomass (1.47 kg vine-1) and yield vine-1 (7.42 kg) were recorded in vines treated with 40% KNO3 through fertigation + 60% SOP through soil and lowest yield vine-1 (5.21 kg) was observed in vines treated with 100% SOP through fertigation. Vines, which received 60% KNO3 through fertigation + 40% SOP through soil, had recorded maximum percent of fruitful canes vine-1 (51.31).
