Is cowpea high in yield?

The yield of cowpea is very high, with an annual yield of about 1,700 to 3,000 kilograms per mu. However, the specific yield will vary depending on factors such as variety, climate, and geographical location. For example, Zhijiang 19, Zhangtang and Dou are all high-yield varieties.

How to grow cowpea for high yield

1. Selection of improved varieties

Before planting cowpea, it is best to choose some seeds with higher yields, such as the Zhijiang series, Yandai cowpea, ground cowpea, seven-inch cowpea, eight-inch cowpea, Yangjiang series, etc.

2. Sowing time

Early spring cowpeas can be sown and raised in March and April, and can be directly sown under plastic film after mid-April. Spring and summer cowpeas should be sown in early to mid-July.

3. Land preparation and ridge making

Before planting, the planting land needs to be deep plowed and fertilized. Crop rotation is required for more than two years. It is best to apply about 3,000 kg of base fertilizer per acre of land. 25-30 kg of superphosphate can also be used.

4. Reasonable density planting

In early spring, cowpeas need to be planted before the true leaves unfold. Follow the principle of planting small and dry crops, and sow two plants in each hole. If it is summer or autumn cowpeas, you can sow 4-5 seeds in each hole.
