What causes many empty pods in soybeans? Latest analysis
Soybean cultivation holds a very important place in our country, because most of our country's grain and oil comes from soybeans, and soybeans have strong adaptability, so they can be planted all over the country. However, some farmers have reported that many empty pods appeared in the soybeans they planted. Why is that? Since there are many causes of empty pods in soybeans, the editors of Qinnong Web have put together a simple summary. Let's take a look below.
Causes of empty pods in soybeans
1. Variety problems
Although soybeans have strong adaptability, that does not mean they can still grow well and achieve high yields in unsuitable environments. So one of the most basic causes of empty pods in soybeans is improper variety selection. Next, if a late-maturing variety is planted late, this will cause a large number of empty pods to appear, because by the time harvest season arrives it has not matured at all, and due to seasonal issues it will not mature anymore either. So we must pay attention to variety selection.
2. Timing problems
Soybeans have a suitable time period for planting. Generally, if planting is done during the optimal growing time for soybeans, combined with later management, then basically no empty pods will appear. The correct planting time is generally from June to August, and the best is to plant early-maturing varieties in June, so that the high-temperature period can be avoided.
3. Continuous cropping on the same land
Soybeans cannot be planted in continuous cropping on the same land, which means that if soybeans are planted this year, they cannot be planted again next year; the land must be changed for planting, because each time they are planted, the trace elements in the soil suitable for soybean growth will decrease, causing soybeans to be unable to grow normally. In addition, planting crops such as melons and fruits and then using the land for soybeans can also cause empty pods.
4. Improper fertilizer and water management
If soybeans still develop empty pods when other planting conditions are normal, then the biggest cause is improper fertilizer and water management and unscientific fertilization, such as over-applying urea, applying too little potassium fertilizer, or applying other necessary trace fertilizers improperly. This can very easily cause malnutrition in soybeans, so the appearance of empty pods is hardly surprising. The next issue is too much water, failure to drain in time, or the soil no longer having sufficient water for soybean growth but no watering being done, or watering not being done in time. This can also lead to empty pods.
5. Weather effects
The influence of weather on empty pods in soybeans is mainly shown in three aspects. The first is high temperature with little rain, the second is high temperature with much rain, and the third is low temperature with much rain. If the temperature reaches above 38 degrees, soybeans may stop flowering, or stop growing, or may even be burned to death. Next is excessive rainfall, soil hardening, and poor drainage, which can also lead to empty pods or even dead, stunted plants.
Prevention and control methods
Actually, the methods for preventing and controlling empty pods in soybeans are very simple. First, choose soybean varieties suitable for local planting. Second, pay attention to crop rotation and choose good plots for planting. Then, match fertilizers well and fertilize reasonably, without over-applying nitrogen fertilizer. Also, drain water in time and loosen the soil for aeration. Finally, make preparations in advance for drought and flood disasters, and manage the soybeans in the field in a timely and effective manner.
