Genetic improvement in components of economic importance along with maintaining a sufficient amount of variability is always the desired objective in the any maize (Zea mays L.) breeding program which will be handled under the conditions of Haramaya, Eastern Ethiopia. Therefore, an experiment was conducted using (27) and (3) check/control varieties to determine the genetic variability of maize genotypes at Haramaya, eastern Ethiopia. The study results revealed that significantly the tallest plant heights for (PH) were recorded from (3) (170 cm) and (18) (167.5 cm) genotypes whereas the shortest PH were recorded from (13) (117.5 cm) and (23) genotypes (120 cm). Good plant aspects (PA) were obtained from genotype 12, 22 and 26 (PA-1.5) and poor PA were attained from genotype 1 (PA-2.5). Besides, genetic and phenotypic variances were estimated for seven components. The highest genotypic coefficients variation (GCV) and phenotypic coefficients of variation (PCV) were calculated from grain yield (GY – 23.39%). Comparatively the higher GY were attained from the genotypes of 3, 9 and 12. It can be concluded that almost all components of the PCV are greater than the GCV. Superior selected genotypes are recommended to the researchers /breeders to develop disease resistant and high yielder varieties to increase maize production by farmers under Haramaya and other similar agroecologies.

<span>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.</span>
