Table 3 Summary of farmers’ view on different cowpea cropping systems during the focus group discussion sessions across three States in the dry savannah areas of Nigeria in 2017

From: Appraisal of cowpea cropping systems and farmers’ perceptions of production constraints and preferences in the dry savannah areas of Nigeria

Locationa Comments on cowpea cropping systems
Sole Intercropping
Albasu Common here due to project demonstrations Used for a late-maturing variety
Birnin Gwari It is associated with high insect problems. Often not used due to limited access to land This system provides assurance against crop failure and weather conditions
Bunkure Good for market-oriented growers, since it gives higher yield and returns Provides more food for families. Cowpea benefits from maize’s residual fertilizers
Dandume No adequate land for sole cropping Intercropping is more preferred
Danja Few farmers here plant cowpea in sole cropping. Phosphate fertilizers like SSP are not used by many due to non-availability. Fertilizers, in addition, lead to high vegetative growth of cowpea Intercropping is the most prominent among farmers here due to the ease of management of the system
Giwa It yields more but demands a lot of attention It is easier to manage and provides other benefits
Kaita It is difficult to manage due to the need to spray a lot of insecticides, and where there is no means, the field gets destroyed by insects Planted with sorghum, millet, or groundnut on some farms. Intercropping guarantee dual benefits
Kajuru This is more suitable and often used for early maturing varieties It is popularly for late-maturing varieties, thereby do not require much pest controls
Makarfi Not too popular here Cowpea is grown mainly here with groundnut, sesame, and maize
Matazu Needs phosphate-based fertilizers such as SSP Planted with millet, maize, and groundnut
Minjibir It is high yielding and requires a lot of resources such as insecticides to manage Requires less investment and grains become mature during the harmattan season, making it easier to manage
Tsanyawa Good for early maturing varieties, gives more yield for sale and consumption. It needs more fertilizers than intercropping Late-maturing varieties are planted, more popular due to limited land. Improved varieties do not grow well in intercrop while farmers prefer intercrop
