The Performance of Zea mays as Influenced by NPK fertilizer Application

Field trials were made to estimate the effect of NPK 15:15:15 fertilizer on the growth and yield of maize were conducted over a two year period. NPK fertilizer applications significantly increase plant height, stem girth, number of leaves, leaf area, leaf area index, dry matter accumulation and yield. The optimum level of NPK 15:15:15 fertilizer for successful production of maize grains was 400 (60 kg N + 27.16 kg P + 49.80 kg K) kg / ha compound fertilizer based on the fact that it had the greatest dry cob yield (12.44 t / ha), grain yield (7.95 t /ha), relative grain yield (2.26) and 100-seeds weight (11.62g).
