What fertilizer is needed to grow peanuts for high yield?

Peanuts are a common economic crop with a wide planting area. If you want to achieve high yields in peanut planting, you must pay attention to fertilization. Farmers can effectively improve the yield and quality of peanuts through scientific and reasonable fertilization. So what kind of fertilizer is needed to achieve high yield of peanuts? Let’s take a look with the editor below.

1. What kind of fertilizer is needed to achieve high yield of peanuts?

1. Base fertilizer

Basal fertilizer is the basis for high peanut yield and should be mainly organic fertilizer , combined with phosphorus fertilizer and potassium fertilizer. Generally, 1000-2000 kg of decomposed organic fertilizer, 30-50 kg of superphosphate, and 15-25 kg of potassium sulfate can be applied per mu.

2. Fertilizer

When sowing, a small amount of nitrogen fertilizer and molybdenum fertilizer, such as 5-10 kg/mu of urea and 20-30 g/mu of ammonium molybdate, can be used to promote seed germination and root growth.

3. Topdressing during the seedling stage

During the peanut seedling stage, if the plant growth is weak, you can apply appropriate nitrogen fertilizer, such as 5-10 kg/mu of urea, to promote seedling growth.

4. Topdressing during the flowering period

Peanuts require more nutrients during the flowering and needle-forming stages. At this time, nitrogen and potassium fertilizers can be applied, such as 10-15 kg/mu of urea and 10-15 kg/mu of potassium sulfate.

5. Topdressing during pod setting period

The pod-setting stage is the critical period for peanut yield formation and requires intensive fertilization. You can apply nitrogen and potassium fertilizers, such as 10-15 kg/mu of urea and 10-15 kg/mu of potassium sulfate.

6. Foliar spraying

In the middle and late stages of peanut growth, foliar fertilizers , such as 0.2%-0.3% potassium dihydrogen phosphate solution, can be sprayed to supplement phosphorus and potassium and promote full grains.

7. Trace elements

Peanuts also require trace elements such as calcium, boron, and zinc, which can be applied in appropriate amounts in the base fertilizer or supplemented by foliar spraying during the growth period.

8. Controlled release fertilizer

Controlled-release fertilizers can release nutrients slowly and are suitable for the long-term nutrient needs of crops such as peanuts.

2. Peanut fertilization method

1. Reasonable amount of fertilizer

Determine the amount of fertilizer to be applied based on factors such as soil fertility, peanut growth conditions, fertilizer type and content. Avoid waste and environmental pollution caused by excessive fertilization, while ensuring that peanuts have adequate nutrient supply.

2. Evenly apply fertilizer

Ensuring that each peanut plant receives the same nutrient supply helps improve yield uniformity. During the fertilization process, pay attention to spreading the fertilizer evenly on the soil surface and mixing it thoroughly with the soil.

3. Fertilize in different seasons

Adopt a seasonal fertilization strategy based on the growth cycle and nutrient requirements of peanuts. Apply nitrogen fertilizer in moderation in the early stages of growth to promote leaf growth, increase the application of phosphorus fertilizer during flower bud differentiation and growth periods, and appropriately increase the supply of potassium and calcium fertilizers during fruit expansion and maturity periods.

The above is an introduction to what kind of fertilizer is needed to achieve high yields when growing peanuts. Fertilization for peanuts should be adjusted according to soil fertility and peanut growth conditions, avoiding excessive application of nitrogen fertilizer to prevent the plants from growing too tall.
