An experiment was conducted at the Agricultural Research. Farm of NWFP Agricultural University, Peshawar during Spring, 1999 to study the response of maize varieties to different planting methods. The experiment was laid out in RCB design with split plot arrangement and four replications. Planting methods studied were ridge planting, furrow planting, line planting and broadcast planting. Varieties included in the experiment were Hybrid-922, Sarhad White and Sweet corn. Urea and DAP were used as sources of basal dose of fertilizers at the rate of 200:100 N:P kg NP per hectare. Planting methods, varieties and their interaction significantly affected all the parameters studied except for emergence per m-2 which was only significantly affected by varieties. Number of cobs per plant (1.03), cob length (20.32 cm), number of grains per cob (451.83), grain weight per cob (128.9 g), biological yield (53.91 kg/plot) and grain yield (4629.62 kg/ha) had maximum values in ridge planting. Maximum cob length (25.07 cm), number of grains per cob (614.14), grain weight per cob (217.26 g), biological yield per plot (73.82 kg) and grain yield/ha (6791.66 kg) were noted in Hybrid-922.
