Aceh is one of the centers for hybrid maize production with an area of 47,160 ha and a production of 205,125 tons. Increased production of maize can be achieved by applying technological components, including the use of superior varieties and recommendations for fertilization and spacing to obtain maximum results. The purpose of this study was to determine the response of growth and yield of three high yielding varieties of hybrid maize to the fertilization package. This research was conducted from July to October 2019 in Bireun District, Aceh Province. The research used a randomized block design (RBD) with 3 replications and for each treatment 15 plants were assigned as samples. The first factor is the variety (V), namely V1: Pioner 32; V2: Bima 19, and V3: Bima 20. The second factor is the fertilizer package (P) which consists of 2 (two) levels: P1 (recommendation) (urea 270 kg / ha, NPK 400 kg / ha, KCl 50 kg / ha); P2 (specific location) (urea 150 kg / ha, SP-36 75 kg / ha, NPK 300 kg / ha). The results showed that the Bima 20 variety with the recommended fertilizer package gave the highest production of 8.03 ton/ha.
