When is the right time to sow autumn beans?

Autumn bean planting time

Autumn beans are soybeans sown in early autumn. They generally have a high protein content and are a high-quality raw material for making condiments such as fermented black beans. Usually, the best time to sow them is at the end of July and the beginning of August. The temperature and humidity at this time are more suitable, and the survival rate of sowing is relatively high.

Key points for planting autumn beans

Seed selection and processing: Before sowing autumn beans, you need to select large, plump, insect-free and dry seeds, and then dry the seeds so that they can germinate better. Before sowing, you need to mix the seeds with rhizobia.

Sowing: Prepare the soil before planting. It is best to plow it more than 20 cm deep. Moisten it with water before sowing. Plant 3-4 seeds at a time to ensure the survival rate of planting. The seeds should be spaced about 30-50 cm apart. Cover the seeds with soil after sowing.

Autumn beans ripe for harvest

Generally speaking, after sowing, if the growing environment is suitable and the beans are properly maintained, they will mature in 5 months. They can be harvested when the soybean stems and leaves begin to turn yellow and the seedlings and pods are dry.

The yield of autumn beans per mu is between 400 and 500 jin. The soybean grain yield per unit area is composed of the number of plants per unit area, the number of pods per plant, the number of grains per pod and the grain weight.
