The objective of this investigation was to study the effect of different dose and method of potash application on potato.

The application of 112.5 kg potash as basal + 2% spray of K2SO4 at 30 days after planting gave maximum total tuber yield of 37.63 t/ ha against a total tuber yield of 21.57 t/ha with no application of potash.
