What fertilizer is good for cowpea topdressing?

What fertilizer to use for cowpea topdressing

Cowpeas can be fertilized frequently with thin layers of fertilizer during their growth period. Generally, topdressing is required in the early growth stages, that is, during the seedling and vine-forming stages.

For topdressing of cowpea, you can choose Gen Shibao. It has a greater demand for potassium and phosphorus during its growth process. Gen Shibao products contain high-potassium and high-phosphorus nutrients. All of its nutrients can be dissolved in water, and cowpea can absorb them quickly, with better effects. For foliar fertilizer spraying, you can choose Nongmi No. 1 or Nongmi Large.

Should I use urea or compound fertilizer for topdressing cowpea?

Use compound fertilizer as topdressing for cowpea. Compound fertilizer and manure should be used alternately, but the amount of manure should be controlled. The compound fertilizer is 10-20 kg/mu.

Cowpea topdressing method

When the cowpea pods grow to 3-4 cm long, top dressing can be carried out. Depending on the different crops and the growth of the plants, top dressing is generally carried out once every half a month. Manure and compound fertilizer should be used alternately. It is best to apply top dressing along with the water, which can speed up the dissolution of the fertilizer. Clean water can be poured between two top dressings to promote photosynthesis. Foliar fertilizer can also be sprayed on the leaves.

Principles of topdressing for cowpea

When applying fertilizer to cowpea, it is necessary to apply fertilizer as needed and at the right time, coordinate fertilization and watering, and use water to adjust fertilizer to avoid fertilizer damage.

Precautions for topdressing cowpea

Top dressing should be carried out according to the different soil fertility, different growth stages and growth potential of cowpeas. The amount of top dressing cannot be increased arbitrarily. For example, less fertilizer should be applied in fertile soil, more fertilizer should be applied in barren soil, more fertilizer should be applied in clay soil, and small amounts should be applied multiple times in sandy soil. Less fertilizer should be applied in the seedling stage, and more fertilizer should be applied in the flowering and pod stage. Fertilizer should be the main fertilizer in the seedling stage, and a combination of organic and inorganic fertilizers should be the main fertilizer in the flowering and fruiting stage. Water should be applied after each fertilization.
