How many bags of fertilizer do you need per acre of maize?

Maize can easily achieve 9 tons/ha (40 bags per acre) with the right agronomy and adequate moisture, but it does require adequate nutrition to achieve this. The amount of fertilizer required is best calculated by multiplying the target yield in tons per hectare, by 20-25 Kg.
