How to Grow Peanuts for High Yield? A Detailed Guide to Peanut Cultivation Techniques

Peanut, also known as groundnut and earth nut, is a nut much loved by the general public and one of the raw materials for oil making, soap making, cosmetics and side foods, with rich nutritional value. So, what high-yield cultivation techniques are there for peanuts?Let's find out together!

1. Pre-sowing preparation

1. Soil selection

For planting peanuts, sandy loam soil that is relatively loose, with a deep soil layer, neutral to slightly acidic, and with good drainage and fertility characteristics is generally chosen; peanuts grown in this kind of soil are high-yielding and of good quality.

2. Rotated land

Remember that continuous cropping of peanuts is bound to reduce yield. According to relevant experiments, one year of continuous peanut cropping reduces pod yield by more than 15%, and more than two years of continuous cropping reduces yield by more than 30%. Therefore, when choosing land with continuous cropping, be sure to disinfect the soil and improve soil fertility.

3. Land preparation

Choose large peanut seeds; large seeds have high fat content and need a lot of water and oxygen when germinating and emerging. The requirements for land preparation before sowing are that the soil should be loose, fine and crumbly, not compacted, with moderate water content and good drainage.

2. Sowing preparation

1. Sunning the seeds

About one week before sowing peanuts, sun the pods continuously for 2-3 days. The purpose is to improve seed vigor, ensure uniform emergence and increase the germination rate. In addition, through sunlight exposure and high-temperature disinfection, pathogens on the pods will be killed, reducing the incidence of disease in the peanut field and saving effort for later sowing.

2. Seed selection

When selecting pods, shelling will be carried out, and off-type pods that do not match the variety characteristics as well as sprouted, insect-damaged and rotten pods must be removed at any time. When selecting kernels, choose fully developed and plump peanut kernels, otherwise high yield cannot be achieved.

3. Peanut shelling

The time for shelling must not be too early, because after shelling the peanut seeds easily absorb water, enhancing respiration, speeding up enzyme activity, promoting material transformation and consuming a large amount of water, which will reduce germination ability. Therefore, the closer the peanut shelling time is to the sowing time, the better.

3. Sowing methods

1. Peanut seed germination requires a suitable temperature, preferably 12-15°C, so sowing should be carried out only when the soil at a depth of 5 cm has a constant ground temperature above 12°C. Under permissible conditions, early sowing at the right time can relatively extend the peanut growth period, bring earlier flowering, more side branches and a well-developed root system, also creating conditions for high yield.

2. Sowing methods

According to the planting method, we can divide it into open-field sowing and film-mulched sowing. The sowing density should be controlled at about 20-25 cm front, back, left and right, with single-seed sowing; the sowing depth should be about 5 cm, and the secret is to sow deep when dry and shallow when wet.

4. Fertilization techniques

With autumn land preparation and ridge making, apply decomposed barnyard manure, kang-hole soil, composted green manure, etc., at 15,000-30,000 kg per hectare; for ridge cultivation, open furrows and apply sparsely, for bed cultivation, broadcast. In ridge cultivation, farm manure can also be applied sparsely before sowing in the sowing year. At sowing, apply diammonium phosphate at 150-225 kg/hectare and potassium sulfate at 75-120 kg/hectare as seed fertilizer. For acidic soil, apply lime with the base fertilizer: if the pH value (acidity and alkalinity) is 6.0-6.5, apply lime at 450 kg/hectare; if the pH value is 5.5-6.0, apply lime at 675 kg/hectare.
