A field experiment was conducted to determine the effect of seed size on maize (Zea mays L.) performance. Among three genotypes under study the seed size categories and their interaction showed non significant effect on yield, yield components, photo biomass production and quality of maize under Faisalabad agro-meteorological conditions. All the parameters including germination, number of plants per plot, plant height, number of cobs per plant, number of rows per cob, number of grains per cob, 1000 grain weight, seed yield, stalk yield biological yield, harvest index and protein contents were increased with Golden variety, bold seed sizes but the difference were non significant.
