This paper was statistical experimental design to analyze and compare the effect of various inorganic manures on the growth of varieties of maize (Zea mays) in agricultural sector and their significances. Randomised complete block design was employed in analysis of data obtained from secondary source. From the employed analysis of variance test to examine the significance of the effect of inorganic fertilizers on different varieties of maize, the following facts were deduced: the null

... of factor A, which is inorganic fertilizer for the height of the plant, the number of leaves per plant were accepted at 0.05 level of significance. Similarly, the null hypothesis for factor B which is varieties of maize for the number of leaves and height per plant were accepted at 0.05 level of significance. It shows that there is s significant difference in growth of maize when various inorganic fertilizers were applied. Finally, any of the inorganic manures must always be use in order to increase the growth and yield of maize.
