In the whole growing period of cowpea, reasonable water and fertilizer management is one of the important measures to ensure the high yield of cowpea. Generally speaking, cowpeas do not need to be fertilized after they are inserted into the shelf and in front of the seat. Because, during this period, the amount of fertilizer needed is not large, and the amount of base fertilizer applied before sowing is enough for the growth of cowpea.
