With good field management of peanuts, a yield of 800 jin per mu is within reach
Peanuts have always been a relatively high-yielding crop, and yields generally vary from plot to plot, but reaching a yield of 800 jin per mu is still very much within reach. Of course, this depends on proper planting management. Here I will share some technical points on achieving high peanut yields.
1. Soil
Peanuts are not very demanding when it comes to soil, but the soil best suited to peanut growth is preferably loose, fertile, slightly acidic sandy soil. Alkaline soil is not very favorable for peanut growth. Soil with a high calcium content is even more favorable for peanut growth.
Secondly, peanuts are not tolerant of continuous cropping, which can easily lead to soil-borne diseases such as root rot, stem rot and other serious diseases, affecting peanut yields. In addition, many soil-dwelling peanut pests become further aggravated during continuous peanut cropping. Therefore, after the previous peanut crop is harvested, be sure to clean the peanut field thoroughly and plow deeply to reduce the occurrence of disease. For plots with mild disease, one crop per year is acceptable; for severe cases, one crop every two years.
2. Varieties
Peanut variety is also a major factor affecting peanut yield, so doing a good job of seed selection is also very necessary. There are currently quite a few high-yielding peanut varieties on the market, but when purchasing peanut varieties you must choose suitable varieties according to local conditions, and of course buy seeds from a reputable seed station rather than going for cheap options.
Here are a few relatively high-yielding peanut varieties: Huayu 33, Yuanza 9847, Jihua No. 4, Zhonghua 16, Yueyou No. 7, and others. These peanut varieties have fairly good stability, but they should still be planted according to local conditions. For example, Yuanza 9847 is more suitable for planting in areas north of the Huai River, while Zhonghua 16 is suitable for planting in Sichuan, Anhui and other places.
Besides seed selection, another step needed for high peanut yields is peanut seed coating, that is, treating the seeds before planting. Peanut seed coating can reduce infestation by soil-dwelling pests during the growing period, effectively reducing dead seedlings and missing plants and reducing soil-borne diseases. It also increases peanut yields.
For peanut seed coating, imidacloprid-series or chlorpyrifos-series products are generally chosen for seed treatment.
3. Planting
Planting generally needs to ensure uniform peanut emergence and reduce missing plants. Plant at a reasonable density, generally sowing about 10,000 hills per mu, with two peanut seeds placed in each hill. During the stage when peanut seedlings emerge evenly, pay attention to clearing the seedlings by pushing away the soil around the peanut seedlings to let the two cotyledons receive light. This helps increase peanut yields.
4. Fertilization
Before planting peanuts, apply sufficient base fertilizer. In the early stage, the nitrogen-fixing ability of peanuts is relatively weak, so they rely on the base fertilizer. Generally, once peanuts have pegged in the middle and late stages of growth, do not apply fertilizer again.
