A3x5 factorial experiment in a completely randomized design was conducted under screen house condition to evaluate the responses of maize cultivar to organomineral fertilizer. The factors were fertilizer application (0,4.0 and 6.0 tha-1) and maize cultivar (ACR30T21 COMP3c3; Oba Super1; AK950MRESRW(YELLOW) and ACR91SUWANI –SRCI). All treatments were replicated three times. The crop parameters monitored included height, leaf length, number of leaves and biomass yield. Data analysis was through ANOVA and means were separated using the Duncans\'s Multiple Range tests (DMRT) at 5% probability level. Plant height, leaf length and biomass yields of all maize cultivars responded to organomineral fertilizer applications. Generally, the order of response was 0.0
