What fertilizer is good for growing mung beans?

Mung bean fertilizer

Mung beans have the ability to fix nitrogen and are very resistant to barrenness. A small amount of organic fertilizer can produce high yields. Generally, they do not require a lot of fertilizer or water, and the density should not be too high. Sow 6,000 to 8,000 holes per acre, with one to two beans in each hole. Among the three major elements, nitrogen, phosphorus and potassium, potassium fertilizer is more important.

Mung bean fertilizer

Mung beans can use farmyard manure as base fertilizer. Generally, 2,500 kg of farmyard manure and 20 kg of superphosphate are applied per mu, along with an appropriate amount of potassium fertilizer, and applied evenly to the land to be sown to ensure the phosphorus and potassium nutrition needs throughout the growth and development stage.

Mung bean topdressing

Mung beans need to be top-dressed during the flowering period. You can use fertilizers containing nitrogen and phosphorus, apply nitrogen-phosphorus compound fertilizers, or spray urea plus potassium dihydrogen phosphate, divided into 2-3 times. Mung beans are sensitive to trace fertilizers, and the application of trace element fertilizers has obvious effects.

Fertilizer for mung bean growing period

The root system of mung bean seedlings is underdeveloped, their ability to absorb nutrients is limited, and their nitrogen fixation is incomplete. If you want to increase the yield, you must apply seedling-promoting fertilizer in a timely manner. Generally, 3-4 kg of urea is applied per mu to promote the healthy growth of the seedlings.

Fertilizer for mung bean fruiting period

During the flowering and podding stage of mung beans, you can spray potassium dihydrogen phosphate and boron fertilizer on the leaves 1-2 times to achieve the effect of increasing pods and grains.

The correct way to fertilize mung beans

The base fertilizer for mung beans is human feces, wood ash, kang soil, and pig, chicken, and sheep manure, with an application rate of 1,000-3,000 kg per mu. During the seedling and flowering stages, urea or compound fertilizer should be applied by digging furrows between the rows. Urea and potassium dihydrogen phosphate can be sprayed from branching to harvesting. Generally, spraying is done once every half a month. Micro-fertilizer should be sprayed on the leaves during flowering and podding.

Notes on fertilizing mung beans

1. Understand the effective period of spraying. Generally, spraying is carried out during the peak period of phosphorus and potassium nutrients in the flowering period of mung beans. Fertilization should not be done on rainy days, with morning dew, or at noon on sunny days. It is advisable to spray before 10 am and after 4 pm.

2. Master the dosage and concentration of spray fertilizer. Use 0.4% potassium dihydrogen phosphate solution at a dosage of 500-1000kg/hm2 (2-4kg/hm2 potassium dihydrogen phosphate). Spray the whole plant evenly. Do not spray too fast. Both sides of the leaves need to be covered with fertilizer.
