    The primary factors those influenced yield potential of maize crop are genotypes, environment and interaction between them. Thus Evaluation of different maize varieties under different environmental condition helps to select the superior one in its yield potential among treatments. To verify this fact the field experiment was conducted during rainy season with three planting times, at Bako and Uke in 2016. Planting times were designed with 7 days interval among each planting time for each location. The first planting was done in may 25/ 2016 and in may 27/2016 for Uke and Bako respectively. The experiment was laid out in a Randomized Complete Block Design with three replications. Twenty maize varieties were planted in uniform spacing of 75x30 cm to understand the influence of sowing time, location and varieties on grain yield of maize, and to selected suitable variety. The analysis of variance showed that a significant (P<0.01) effects of panting times and varieties on grain yield of maize. The maize variety BHQPY 545 was superior in grain yield (10445 kg/ha) and number of cobs (87161 cob/ha) at both locations and at all planting times. However statistically similar grain yield (9616.3kg/ha) was also obtained in another maize variety BH 546. But BHQPY 545 performed well in all location with similar input and management. Therefore BHQPY 545 is the most suitable and productive variety under these locations. Although the results are one year experiment the variety performed well at two locations and number of cobs per plant is genetic factor. Thus BHQPY 545 variety should be grown at Bako and Uke to produce high yield.
