What are the reasons for low broad bean yields? The latest analysis is here

In some regions, broad beans are also called "Buddha beans" and are a fairly common legume vegetable. They can also be used as food, feed, and green manure, and are welcomed by many people. When growing broad beans, the thing everyone cares about most is certainly the yield. However, sometimes the yield of broad beans is not very ideal, so what causes the low yield of broad beans? Today, the editor will give everyone a brief introduction. Let's take a look below!

1. Climate

Climate factors are one of the main reasons for the low yield of broad beans. Especially during the flowering and podding stage of broad beans, if the climate is relatively harsh and there is rainy weather, then the flowers and pods of broad beans will drop flowers and pods due to wind and rain. Moreover, even if the flowers do not drop, the pollen may burst from absorbing too much water after being washed and broken by rainwater. This directly affects the pollination of broad beans, thereby causing a decline in yield. Therefore, we should pay attention to good management, and it is best to grow them in a greenhouse to avoid the effects of adverse weather.

2. Moisture

Although broad beans have a certain demand for moisture during growth, when watering we must pay attention to controlling the amount of water. If too much water is applied, causing waterlogging in the soil, or if drainage is not done in time after rain and the soil moisture becomes too high, then the soil permeability will be reduced, the roots of broad beans will have difficulty breathing, and root rot may also occur. They cannot normally absorb and transport nutrients and water, and the broad bean plants cannot grow normally under long-term conditions of fertilizer and water deficiency. In severe cases, this leads to death, and the yield will naturally decline as well.

3. Nutrition

Nutrition is certainly an indispensable substance in the growth process of broad beans. When planting broad beans, we should not only apply sufficient base fertilizer, but also do a good job of topdressing according to the growth conditions of broad beans. To meet the nutritional needs of broad bean growth, if broad beans lack nutrition during growth, the impact on their growth is very great. Especially when lacking basic elements such as nitrogen, phosphorus, and potassium, as well as trace elements such as boron, it will lead to reduced broad bean yields. However, also note that too much fertilizer should not be applied, especially nitrogen fertilizer. Excessive nitrogen fertilizer easily causes plant flower and pod drop, excessive vegetative growth, and so on, leading to reduced yield.

4. Pests and diseases

⟦NL>Pests and diseases are also one of the main reasons for low broad bean yields. Common pests and diseases in broad bean growth include rust, red blight, and aphids. These pests and diseases will harm the growth of broad bean plants to varying degrees, causing flower and pod drop in broad beans. This seriously affects yield, so during planting we must pay attention to the prevention and control of pests and diseases. Strengthen management, control fertilizer and water well, disinfect regularly, eliminate field pests and pathogens, ensure normal growth of broad beans, reduce the harm of pests and diseases, and thereby increase yield.

The above is a brief introduction to the reasons for broad bean yield. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
