What is the rate of fertilizer application in maize ?

Apply NPK fertilizers as per soil test recommendation as far as possible. If soil test recommendation is not available adopt a blanket recommendation of 135:62.5:50 NPK kg/ha. Apply quarter of the dose of N; full dose of P2O and K2O basally before sowing. In the case of ridge planted crop, open a furrow 6 cm deep on the side of the ridge, at two thirds the distance from the top of the ridge. Apply the fertilizer mixture along the furrows evenly and cover to a depth of 4 cm with soil.
