Effect of different phosphorus levels on growth and yield of three varieties of cowpea (vignaunguiculata (l) walp) in mubi north local government area, adamawa state, Nigeria
This study determines the Effect of different Phosphorus levels on growth and yield of three varieties of cowpea (VignaUnguiculata (L) Walp) in 2016 rain fed cropping season. Phosphorus is very important for cowpea production in many tropical African soils with inherent low phosphorus fertilizer. Most farmers in this locality do not have access to phosphorus fertilizer. Selection of cowpea lines that produce good yield under low soil phosphorus or those with high phosphorus use efficiency can be a low input approach to solving this problem.
