What to Do When Soybeans Flower but Do Not Set Pods? A Detailed Guide to the Latest Solutions

Soybean is a common crop, widely used in soy products and dairy products, with significant economic benefits, but during cultivation it often shows the phenomenon of flowering without setting pods, that is, flowers but no pods. This affects farmers' income and is a real headache, so what causes soybean flowers but no pods? Come with Qinong Net to look at the solutions for soybean flowers but no pods.

1. Variety reasons

Soybean is a common crop, with a long history of cultivation in China. After years of breeding and cultivation, there are many varieties. When planting, if you choose a variety unsuitable for the local planting environment, it will cause a phenomenon of “not adapting to the local conditions”, and symptoms of flowers but no pods may appear.

Solution: When choosing a variety, identify the soybean brand clearly and choose a variety suitable for local planting and growth.

2. Improper sowing time

The sowing time of soybean is extremely important. If sown too early or too late, missing the best sowing time, and the climate changes, when high temperatures or a high-temperature environment are encountered during growth, soybean photosynthesis weakens while respiration strengthens, causing excessive nutrient consumption, which is unfavorable for soybean flowering and pod setting.

Solution: Master the correct sowing time. Soybean sowing time is divided into spring sowing and summer sowing. Spring sowing is around Qingming, while summer sowing is after the wheat harvest. The climate varies by region, so sowing also differs slightly, but the overall difference is not great.

3. Improper fertilization and lack of elements

Some farmers, in order to promote rapid soybean growth during planting, apply nitrogen fertilizer excessively and in excessive amounts during the growth period, leading to excessive nutrition, excessive vegetative growth of the plants, and fertilization that is too single, with other trace elements lacking, and the soil compacted and cloddy with poor permeability, which is unfavorable for flowering and pod setting. In most cases, boron deficiency can also induce the phenomenon of flowers but no pods.

Solution: Pay attention to the method when fertilizing. Do not use only one type. Balance various fertilizers. In particular, prevent excessive application of nitrogen fertilizer, and be sure to apply phosphorus and potassium fertilizers together. It is recommended to mainly use base fertilizer, and later apply organic fertilizer or compound fertilizer as topdressing to maintain the supply of elements.

4. Continuous cropping

Soybean is a crop that avoids continuous cropping and repeated cropping. Some farmers, for convenience, plant on the same field all year round. According to research, the disease rate of plots continuously planted with soybean for two years reaches 50%, while the disease rate for more than three years is basically 100%, and the disease severity is about 80% higher than usual.

Solution: Implement reasonable crop rotation, rotating with other non-legume crops for 1-2 years, such as vegetables and melon and fruit crops. This can improve soybean yield and quality.

The above are the solutions to soybean flowers but no pods brought by Qinong Net. In addition, poor soil permeability and poor drainage can also cause symptoms of soybean flowers but no pods. The issue of soybean flowers but no pods is introduced here. We hope it can help you.
