Abstract: Potassium (K) is deficient in Pakistani soils and maize require large amount of K for healthy growth. An experiment with six levels (0, 25, 50, 75 100 and 125 kg ha-1) of K was carried out at Agronomy Research Farm of the University of Agriculture Peshawar during summer 2016. Maize hybrid Babar was sown manually on June 24. Treatments were laid out in randomized complete block design with three replications. Potassium was applied as murate of potash (MOP) during seedbed preparation. Analysis indicated a significant effect of potassium levels on maize phenology (days to tasseling, silking, maturity), growth (plant height, leaf area index), yield components (grains ear-1, 1000 grains weight) and grain yield. Data showed that with increase in K levels day to phenology decreased accordingly with maximum days in control plots.
