The food security is a huge problem with the increase in population of the Pakistan. Maiz (Zea mays) is one of the major cereal crop and has the capability to compete with the production as well as supporting the controlling applications. As, the modern genotypes has the good potential to resist with the potassium (K) application into the field, an experiment was conducted on K levels with 0, 30, 60 and 90 kg ha-1. Maize genotypes viz MM-50, MM-44, ZMS-52, ZMS-51, ZMS-40, ZMS-06, GV-41, Kiramat-2C, 325-PW and Babar-1C were tested into the field. Our results concluded that K levels had a significant effect on grain yield and yield components. Application of K at 60 kg ha-1 showed good yield compared to all other levels of K applications. The tested genotypes also had a significant effect on the tested traits. The genotype (MM-50) showed maximum grains yield (3924 kg ha-1) and maximum yield components to all the genotypes. Maximum grains yield (4593 kg ha-1) and 1000 grain weight (260.4 g) were obtained from genotype (MM-50) at K level of 60 kg ha -1.
