A study was conducted at the Horticulture farm of Bangladesh Agricultural University, Mymensingh to evaluate the effect of five levels of applied potassium on the growth and yield of carrot. The experiment was laid out in a RCB (randomized complete block) design with three replications with five treatments viz. 0, 30, 60, 90, 120 kg Potassium per hectare. Root yield increased progressively and significantly with the increased application of potassium. Application of potassium 120 kg/ha increased the Leaf number per plant (11.93), root length (16.11 cm), root diameter (5.04 cm), fresh weight (184.8 g) and yield (49.29 t/ha). High dose of potassium also increased cracked and branched root which reduced the marketable quality of yield.
