The correct way to fertilize cowpea

Cowpea is a common vegetable in our lives. When farmers grow cowpea, the yield is relatively high. However, the yield of cowpea grown by some people is not high. This is mainly because the cowpea is not fertilized properly. Let’s talk about the correct way to fertilize cowpea.

1. The correct method of fertilizing cowpea

The absorption of nitrogen, phosphorus and potassium gradually increases during the growth process of cowpea, but the absorption amount varies greatly in different growth periods. The absorption of nitrogen, phosphorus and potassium by climbing cowpea is less during the vegetative growth period, but greater during the reproductive growth period, accounting for the vast majority of the total absorption. Dwarf cowpea is different, absorbing more during the nutritional growth period. The principle of fertilizing cowpea should be based on organic fertilizer , combined with mineral fertilizer, 500-750 kg of decomposed manure and 40-50 kg of superphosphate as base fertilizer per mu. Generally, no topdressing is required during the seedling stage. It can be applied as appropriate during the vine-growing stage. 7 to 10 kg of compound fertilizer can be applied in the late vine-growing stage. If the climate is suitable and the plants grow well, 300 to 400 kg of decomposed organic fertilizer and 15 to 20 kg of compound fertilizer can be added in the late harvest stage to promote growth, increase pod setting, extend the harvest period and increase yield.

2. Six key points and techniques for high yield of beans

1. Crop rotation

Beans belong to the leguminous vegetables. It is not suitable to be planted repeatedly with vegetables of the same family such as eggplant and pepper . Instead, they should be planted in rotation. Generally speaking, it is best to plant once every three years. This can effectively avoid the problem of continuous cropping in the soil and reduce the occurrence of diseases and pests, thereby ensuring the yield and quality of beans.

2. Temperature

During the germination and emergence stage of bean seeds, there are higher requirements for temperature. Generally speaking, temperatures above 20 degrees are more suitable. If the temperature is too low, the seeds will fail to germinate and affect the entire growth cycle. Therefore, when planting, be sure to choose a time when the temperature is warmer.

3. Planting method

There are two ways to plant beans: direct seeding and transplanting. Among them, the growth of directly planted beans will generally be more vigorous, and the yield will be higher than that of transplanted beans. Therefore, if conditions permit, try to choose direct planting, which can better ensure the yield of beans.

4. Watering and fertilizing

During the growth process of beans, watering and fertilizing are very important, but it should be noted that it cannot be done blindly, otherwise it will lead to the excessive growth of the seedlings, thus affecting the later results. Generally speaking, small amounts and multiple times can be adopted to better meet the growth needs of beans.

5. Topping

When the beans grow to a certain height, the vines will begin to grow rapidly. At this time, timely intervention is needed to pinch off a part of the top of the vine appropriately. This can effectively promote more flowering and pod formation of the beans, thereby increasing yield.

6. Management during pod setting period

During the pod-setting period of beans, which is about 20 days after flowering, this is the critical period of bean growth, so you must do a good job of watering and fertilizing, but be careful not to overdo it, otherwise it will cause root and pod rot, affecting the yield, so you must master the principle of moderation.
