Abstract: Field experiment was conducted at KPK Agricultural University, Peshawar, Pakistan to find out the effect of planting methods on the yield and yield components of maize varieties. Analysis of the data revealed that planting methods had a significant effect on days to tasseling, days to silking, plant height, number of plants ha^-1 at harvest, thousand grain weight, grain yield, biological yield, fresh weed biomass m^-2 and non-significant effect on days to emergence, emergence m^-2, number of cobs plant^-1, grains ear^-1, harvest index and dry weed biomass m^-2. Similarly, the effect of varieties was also significant on all parameters except fresh and dry weed biomass m^-2. Maximum emergence m^-2, days to tasseling, days to silking, plant height, number of plants ha^-1 at harvest, grains ear^-1, thousand grain weight, grain yield and biological yield  were recorded in ridge planting method. Similarly, Jalal sown on ridges took maximum days to emergence, emergence m^-2, plant height, number of cobs plant^-1, grains ear^-1, thousand grain weight, grain yield, biological yield, fresh weed biomass and dry weed biomass.
