Abstract
The present investigation was carried out at Research farm of Abhilashi University, Chail Chowk, Mandi during Rabi season 2022 to evaluate the effect of potassium on growth and yield of potato. The experiment was laid down in randomized block design consisting eight treatments in which one is control and others are combination of potassium with three replications. There was significant effect found under various potassium treatments in terms of plant height, number of haulms and haulm diameter at various crop growth stages and fresh and dry weight of plants, marketable yield and harvest index and specific gravity and dry matter content of tubers. The maximum marketable tuber yield was obtained with the split application (basal + foliar spray) of potassium. The findings revealed that the growth and yield parameters were significantly influenced by different split potassium levels.
