What to Do About Low Peanut Yields? Cause Analysis and Solutions

Peanut is one of the main oil crops and an important cash crop in China, widely planted across the country. However, as the planting area keeps increasing, more and more problems have emerged. Many farmers experience low yields when growing peanuts, which seriously affects their income. So what causes low peanut yields? Let's take a look with Qinong Net.

1. Variety causes

Many farmers often use self-bred seeds that have been propagated for multiple generations. These seeds are of mixed varieties, and with repeated planting, the varieties become seriously degraded, leading to reduced disease resistance and low yields, which results in the problem of low production.

Solution: When sowing, choose good seeds that meet market demand, and select varieties with strong disease resistance, strong stress resistance and high yields, such as Yuhua No. 10, Shangyan 9658, Yuhua 9840, etc.

2. Sowing causes

When the sowing time is improper and the best sowing period is missed, or when poor-quality seeds are chosen for sowing, or when seeds are sown directly without treatment, the sowing quality is poor, the seed germination rate is low, and the probability of pests and diseases is also relatively high, thus causing low yields.

Solution: For spring sowing, the best time is when the temperature is stable at 15 degrees; for summer sowing, the earlier the better. Before sowing, sun the seeds, then shell them and select plump, undamaged seeds. Before sowing, seeds should also be treated with chemicals to eliminate the pathogens they carry and prevent diseases.

3. Continuous cropping on the same field

Continuous cropping on the same field not only increases the probability of pests and diseases but also makes pest and disease damage more severe. It also hinders root growth, leading to reduced absorption capacity and nutritional deficiencies. Combined with pest and disease damage, this leads to reduced yields.

Solution: Use rational crop rotation to reduce the harm caused by continuous cropping. When planting, choose to rotate with other crops for 2-3 years. In addition, choose varieties with strong disease resistance and strengthen field management so that the plants grow and develop normally.

4. Improper fertilization

When planting, farmers may fertilize in order to reduce planting costs or may fertilize unscientifically, resulting in fertilization that is too one-sided or excessive. This causes peanuts to lack certain trace elements, or excessive fertilization leads to excessive vegetative growth, which can also reduce yields.

Solution: Master correct fertilization techniques and fertilize according to the growth condition of the peanuts. Fertilization should be reasonably balanced and not one-sided. Ensure the supply of other nutrients needed for peanut growth to improve its yield and quality.

5. Harvesting too early

Some farmers often harvest peanuts early in order to clear the field for the next crop or for other reasons, which causes the peanuts to be harvested before they have fully grown and matured. Generally, harvesting 7-10 days before the suitable harvest time can reduce peanut yields by more than 10%, resulting in lower production.

Solution: As much as possible, wait until the peanuts are fully mature before harvesting. At harvest time, choose to sample and harvest a portion first to check whether they are fully mature before deciding.
