Cultivation techniques of cowpea

Cowpea seedlings are easy to germinate and generally do not need to soak seeds to accelerate germination. The soil at the bottom of the seedbed should be compacted, and it is best to spread loam with a thickness of 6cm to prevent the taproot from penetrating into the soil, producing fibrous roots and damaging the root group when transplanting seedlings.

Cowpea in summer sowing, northern China, generally began to be planted in mid-June, and planting excellent varieties is an important prerequisite for cowpea to obtain high yield.

Before sow, cowpea varieties with good yield and quality should be selecte for planting.

Soaking seeds can kill germs attached to the surface of seeds and lurking in the epidermal cells of seeds, and play a role in disinfection and sterilization.

Cowpea has wide adaptability to soil and is slightly alkali-tolerant. Too sticky low temperature soil is not conducive to the development of roots and rhizobia, and neutral sandy loam with deep soil layer, fertile soil and good drainage grows best.

Because cowpea has a large demand for phosphorus in the growing period, in order to ensure the healthy growth and high yield of cowpea in the future, some diammonium phosphate should be applied before cowpea sowing.
