Measurement of cowpea grain yield and aboveground biomass at maturity by crop cut at plot level
Cowpea is an important grain legume, providing high-protein food for humans and animals. Due to its ability to fix atmospheric nitrogen (N2), it does not require large amounts of N-fertilizer and can have positive effects on the soil quality. Cowpea is a short-duration grain legume of which there ar...

| description | Cowpea is an important grain legume, providing high-protein food for humans and animals. Due to its ability to fix atmospheric nitrogen (N2), it does not require large amounts of N-fertilizer and can have positive effects on the soil quality.
Cowpea is a short-duration grain legume of which there are a large number of varieties with a wide range of growth habits and pod maturing patterns. Figure 1 shows two contrasting cowpea growth types.
The major difference between varieties is the time it takes for them to grow, flower and produce pods. Based on growth characteristics, cowpea varieties can be grouped into three.
•
Determinate: These types stop growing and flowering after a certain number of flowers and pods are formed, and thus the pods mature relatively uniformly and simultaneously.
•
Semi-determinate: These have an indeterminate growth habit. They tend to have a climbing habit that is self-supporting so do not need staking.
•
Indeterminate or runner types: These can climb or spread across the soil surface; they keep growing and forming branches, leaves, flowers and pods over a long period. Indeterminate varieties are harvested multiple times over a long period as the pods mature at different times. They require staking for optimal productivity. |
