Abstract
73 words
Optimal combinations of organic and inorganic fertilizers can
give rise to increased maize yields in nutrient depleted soils. In
this study, we assessed the effectiveness of cowpea residues
and combinations of inorganic fertilizers on maize yield.
Integration of 40 kg/ha N, 10 kg/ha P and 50 kg/ha K and organic
fertilizers improved maize yields significantly. In areas where
cowpea is produced in reasonable quantities, its residues can
be used to improved maize yields.
