Which month is best for planting soybeans?

Soybean, also known as soybean , is a common crop in rural areas. After harvest, soybeans are often used to make foods such as tofu , and are deeply loved by rural residents due to their rich edible value. At the same time, soybeans have many other uses. Let’s learn together which month is the best for sowing soybeans?

The optimal planting time for soybeans is closely related to factors such as local climatic conditions, farming systems and soybean variety types. The following are recommended planting times based on different regions:

1. Northern Region

Spring soybean planting in northern regions usually starts from late April to early May78. During this period, the soil temperature gradually rises and reaches the temperature required for soybean seeds to germinate. Usually, when the daily average temperature of the 5 cm soil layer reaches 10-12°C, it is suitable for sowing. For example, in Jilin Province, the best time for soybean planting is from May 1 to May 15, and the eastern region should complete planting before May 25 at the latest.

2. Southern China

The sowing time of summer soybeans in southern regions generally starts from May to June. In the Huanghuaihai region, the three days before and after the summer solstice are considered the golden season for growing soybeans. In addition, there is a folk proverb that goes "Plant melons and beans around the Qingming Festival", which means that early to mid-April is the suitable sowing period.

3. Other regions

For other regions, the soybean planting time can be determined according to local climatic conditions and the characteristics of the soybean variety. For example, winter soybeans can be planted in November and harvested in March-April of the following year.

4. Notes on sowing

Sowing depth: Soybean sowing should not be too deep, just cover the surface with a layer of soil to facilitate normal germination and emergence of seeds.

Sowing density: Soybeans should be planted sparsely to promote branching and increase fruit set rate.

Seed treatment: In order to prevent diseases and pests and promote uniform and strong seedlings, it is recommended to carry out seed coating treatment.

Weeding and fertilization: Soybean weeding is divided into closed weeding and post-emergence weeding. At the same time, the yield can be increased by supplementing nutrients through the leaves in the middle and late stages of growth.

To sum up, the best planting time for soybeans varies from region to region. It is generally from April to May in spring in the north and from May to June in summer in the south.
