How many jin per mu do peanuts generally yield? Detailed guide to planting time and methods

As an “introduced species”, peanuts rank among the top in both consumption and planting area in our country, so do you know how many jin per mu peanuts generally yield? Do you understand the planting time and methods?

I. Basic facts about peanuts

1. Distribution of peanuts

Peanuts refer to the annual herbaceous plant groundnut, also called earth bean, longevity fruit, potato (Taiwan dialect), Tangren bean or Nanjing bean (Japan), etc. They originated in tropical America and are now widely cultivated all over the world. They are also cultivated in various parts of our country, among which Shandong, eastern Liaoning, the Leizhou Peninsula of Guangdong, the Huanghuai River region, and the coastal hilly and sandy soil areas along the southeast coast are the main producing areas.

2. Value of peanuts

Peanuts are rich in energy, vitamins, protein and dietary fiber, etc., and have the effects of strengthening the spleen and stomach, promoting growth, resisting aging, and stopping bleeding and building blood. Moreover, the oil yield of peanuts is far higher than that of other oil crops, with an oil yield as high as 45%-50%. The relative content of oleic acid in peanuts is as high as more than 50%. Oleic acid is beneficial to the human cardiovascular system and has a lowering effect on high blood lipids and harmful cholesterol in the human body; in addition, peanut oil is used as a lubricant in the textile industry and as a quenching agent in the machinery manufacturing industry.

3. Price of peanuts

At present, in Qingdao, Shandong, common kernel peanuts are purchased at 3.40-3.55 yuan/jin, Weihua 8 common peanuts are purchased at about 3.7, Luhua No. 11 double-seed fruit is quoted at about 7300 yuan/ton, Weihua No. 8 seed fruit is quoted at about 7000 yuan/ton, 9616 seed fruit is quoted at about 7000 yuan/ton, Xiaoriben seed fruit is quoted at about 7600 yuan/ton, Huayu 22 seed fruit is quoted at about 7600 yuan/ton, and Baisha 308 seed fruit is quoted at about 7700 yuan/ton; in Luan County, Tangshan, the price of Tangyou 285 mixed peanuts is about 3.90 yuan/jin, and the price of black peanut fruit is about 4.50 yuan/jin.

II. How many jin per mu do peanuts generally yield?

Under different geographical conditions, varieties and management conditions, the yield of peanuts also varies. Generally, in areas with better management and fertile soil, the peanut yield per mu is 800-1000 jin, and in areas with less fertile land, the yield per mu is 600-800 jin.

III. Do you understand the planting time and methods of peanuts?

The planting time and methods of peanuts are one of the key factors affecting high yield, so if you want to obtain high yield, you must understand the following time and methods clearly!

(1) Planting time of peanuts

Generally, the planting time of peanuts differs according to different peanut varieties and planting regions. Usually, spring and autumn double-cropping peanuts in southern regions are generally sown from February to mid-March each year, while in the spring-summer peanut alternating cropping area of the Yangtze River Basin, sowing is from March to late April each year, and in the northern large peanut areas and main peanut producing areas, sowing is mostly from late April to early May.

(2) Peanut planting methods

1. First soak the peanut seeds to be sown in medicinal liquid, then sow them in the seedbed. After 30-40 days from sowing, transplant the seedlings into plots with deep cultivated soil, flat terrain, convenient drainage and irrigation, suitable soil structure and good physical and chemical properties.

2. For the seedling land, ensure there are no weeds in the field. From the large-scale budding stage to the flowering stage of the seedlings, spray leaf fertilizer and boron fertilizer 3 times at intervals of one week; in addition, nitrogen application at the seedling stage should not be excessive, and it is best to apply trace elements such as boron according to soil conditions for significant effects. Nitrogen, phosphorus, potassium and boron can all be applied as foliar topdressing.

3. Although peanuts are drought-tolerant, their water demand is still relatively large, especially during the flowering and podding stage of peanuts, when they must not lack water. However, in southern regions during periods with more rain, attention should be paid to timely draining excess water.

4. During the growth period, peanuts are prone to damage from peanut rust, early leaf spot, brown spot, late leaf spot and root-knot nematode disease, etc., so growers should promptly take control measures and strengthen field management.
