CROP PRIORITIES
Pests, diseases and growing conditions can produce similar symptoms. Connect field history and diagnosis with the crop stage before choosing an input.
Root-knot nematodes can cause patchy stunting and reduced water uptake, although visible galling varies between cowpea varieties. Distinguish galls from beneficial nodules and obtain a nematode diagnosis. Variety resistance must match the local nematode problem, while rotation decisions should consider the host range of the species present.

Lower-leaf yellowing and progressive wilting require diagnosis rather than an automatic increase in fertiliser. Where root-knot nematodes also occur, assess both problems together: nematode injury can compromise wilt resistance and change the appropriate variety choice.

From establishment to harvest or renewal, the purpose of crop management changes with each stage.
Establish a uniform stand with suitable seed quality and soil conditions. Assess crop-matched inoculation alongside the seed treatment and sowing programme.
Monitor root condition together with water availability and canopy growth. The balance between vegetative growth and pod production depends on the variety and growing system.
Flowering and pod set connect crop growth with harvest potential. Coordinate water, nutrition and crop-health monitoring, with a defined role for each input.
Vegetable cowpea and grain cowpea require different harvest and quality assessments. Maintain nutrition and crop-health observation through repeated picking where applicable.
BIOLOGICAL INPUTS
These products have distinct roles in nutrition, root development and crop management. For a pest or disease, product selection also requires evidence for the identified target and applicable market label.
