Latest Mung Bean Seed Prices and a Detailed Guide to Growing Methods

Mung bean is also known as green small bean, lu bean, zhi bean, etc. It is an annual upright herbaceous plant of the genus Vigna in the Fabaceae family, native to India, Myanmar and other regions, and has a cultivation history of more than two thousand years in China. It is cultivated throughout the north and south, and the seeds are used for food and can also be used to extract starch to make bean paste, vermicelli, etc. Now let us take a look at mung bean seed prices and growing methods!

How much is a jin of mung bean seeds?

The price of mung bean seeds is about 8 to 10 yuan per jin, but it varies depending on seed quality, variety, place of origin and market conditions. Mung beans are cultivated in China's Yellow River and Huai River basins as well as in the provinces of the North China Plain, especially in Sichuan, Henan, Shandong, Anhui, Hubei, Shaanxi, Shanxi, Jiangsu and Liaoning. The sowing rate per mu is generally 3 to 4 jin, and the yield per mu is generally about 200 to 300 jin.

Sowing methods for mung beans

1. Land preparation: Mung beans are drought tolerant and tolerate poor soil, with wide adaptability. They are deep-rooted crops with large cotyledons, so they have stricter requirements for land preparation. Before sowing, the soil should be deeply plowed and finely harrowed to achieve a loose top and firm bottom with uniform depth, otherwise emergence will be affected.

2. Fertilization: Before sowing mung beans, apply 2500 to 3500 kg of farmyard manure and about 10 kg of superphosphate per mu at one time. If fertilization cannot be done at sowing, an appropriate amount of nitrogen and phosphorus fertilizer can be applied as a top dressing in the early growth stage to enhance the nitrogen-fixing effect of root nodules.

3. Sowing period: The growth period of mung beans is generally only 60 to 120 days, and the suitable sowing period is very long. They can be sown in spring and summer. Spring sowing is from late April to early and mid-May, and summer sowing is in mid to late June. Early sowing should be pursued.

4. Sowing: Before sowing mung beans, spread the seeds thinly on a mat and sun them continuously for 1 to 2 days to promote germination and emergence. The main sowing method is drilling, with a row spacing of about 40 cm and a sowing depth of 3 to 5 cm.

Growing methods for mung beans

1. Site selection and intercropping: Mung beans have extremely strong adaptability and can grow in ordinary sandy soil, thin hillside land, black soil and clay soil. They are often intercropped with corn, sorghum, cotton, sweet potato, sesame, millet and other crops, and can be planted on field ridges and in gaps, but continuous cropping should be avoided.

2. Deep plowing and land preparation: Before sowing mung beans, deep plow and finely harrow, carefully prepare the land, level the soil clods, make the soil loose, store water and preserve moisture, prevent soil compaction, keep the top loose and the bottom firm, so as to facilitate emergence and implement crop rotation.

3. Reasonable close planting: The planting density of mung beans should be determined according to variety characteristics and soil fertility. Generally, the principles are: early-maturing varieties dense, late-maturing varieties sparse; upright types dense, semi-vining types sparse, vining types even sparser; fertile land sparse, poor land dense; early sowing sparse, late sowing dense.

4. Cultivation and weeding: After the first compound leaf of mung beans unfolds, carry out the first shallow hoeing together with thinning. After the second compound leaf unfolds, start final thinning and carry out the second cultivation. At the branching stage, carry out the third deep cultivation and earth up around the roots. Cultivation should continue until the rows close.

5. Drainage and irrigation: Mung beans need less water during the seedling stage, and the flowering and podding stage is the peak water requirement period. If drought occurs at this time, timely irrigation should be given, but they are also afraid of waterlogging and flooding. Excessive moisture at the seedling stage can cause root rot and dead seedlings, while waterlogging in the later stage leads to poor plant growth and reduced yield.

6. Reasonable fertilization: The root system of mung beans has nitrogen-fixing ability, so fertilization is often not applied in production. However, in order to increase mung bean yield on medium- and low-yield plots, fertilizer should be added. Generally, about 10 kg per mu of diammonium phosphate or nitrogen, phosphorus and potassium compound fertilizer is applied as seed fertilizer.

7. Timely harvesting: Mung beans should be harvested as they mature according to the situation, but large-scale planting often requires a one-time harvest. The sign for timely harvest should be when 2/3 of the pods turn brown-black. However, under high temperature conditions mature pods are prone to splitting, so harvesting should be done in the morning before the dew dries or in the evening.

Pest and disease control for mung beans

1. Black cutworm

[Damage] Young larvae often gather on the heart leaves or undersides of leaves of seedlings to feed, often eating the leaves into a net-like pattern. Larvae after the 3rd instar bite off the tender stems of seedlings near the ground and drag them into holes, with the upper leaves exposed outside the hole, causing missing plants and broken rows.

[Control] Plow the land, remove weeds, trap and kill adults and larvae, and before the larvae reach the 3rd instar spray with 90% trichlorfon 1000-fold solution, or 2.5% deltamethrin 300-fold solution, or 20% shuguolin 3000-fold solution.

2. Aphids

[Damage] The aphids harming mung beans mainly include bean aphid, pea aphid, cotton long-tube aphid and others, among which bean aphid causes the most serious damage, generally reducing yield by 20 to 30%, and in severe cases by 50 to 60%.

[Control] Spray 2 kg per mu in the morning or evening with 1.5% dimethoate powder or 2.5% trichlorfon powder, etc. A spray of 40% dimethoate emulsion 1000- to 500-fold solution, or 50% malathion 100-fold solution, or 50% phosphamidon emulsifiable concentrate 2000-fold solution can also be used.

3. Red spider mite

[Damage] Adults and nymphs suck plant sap on the underside of leaves. On the surface of damaged leaves, yellow-white spots appear. In severe cases, the leaves turn yellow and dry up, and the field looks scorched. Plants defoliate early, affecting grain formation and leading to reduced yield.

[Control] A spray of 40% omethoate emulsion 2000-fold solution, or 50% malathion emulsifiable concentrate 1000-fold solution, or 50% naled 2000-fold solution can be used, spraying once every 5 days for 2 to 3 consecutive sprays.

4. Viral disease

[Damage] Mung beans can develop the disease from after emergence to the adult plant stage. Mottling appears on the leaves or the green parts are uneven, and the leaves shrink. Symptoms on pods are not obvious.

[Control] At the early stage of disease, begin spraying 20% virus A wettable powder 500-fold solution or 15% virusbike wettable powder 500- to 700-fold solution.

5. Brown spot

[Damage] At the early stage of disease, water-soaked brown small spots appear on the leaves. In severe cases, the lesions merge into patches and soon dry up. Pods affected show brown lesions, and later the lesions expand and the pods dry up.

[Control] At the early stage of disease, spray 50% duofumeiwei (carbendazim and diethofencarb) wettable powder 1000- to 1500-fold solution + 75% chlorothalonil wettable powder 800-fold solution, once every 7 to 10 days, for 2 to 3 consecutive treatments.

6. Root rot

[Damage] At the early stage of disease, the heart leaves turn yellow. If the root system is pulled out and observed, rotting can be seen on the lower part of the stem and the upper part of the main root, and the plant then withers and dies.

[Control] At the early stage of disease, choose 75% chlorothalonil 600-fold solution, or 15% fulanling 600-fold solution, or 70% thiophanate-methyl 1000-fold solution for spraying. Spray once every 7 to 10 days, for 2 to 3 consecutive sprays.

7. Leaf spot

[Damage] Early stage shows small water-soaked spots, later becoming necrotic spots, perforating and falling off, and plants decline early. The disease is severe during the flowering and podding stage and under high temperature and high humidity.

[Control] Starting at the bud stage, use 50% carbendazim wettable powder or 50% benlate 1000-fold solution plus plant growth regulators, once every 7 to 10 days, for 2 to 3 consecutive sprays, to control the disease epidemic.

8. Powdery mildew

[Damage] Small white powdery lesions are scattered on the leaf surface. When the climate is suitable, the lesions expand rapidly, and the diseased leaves are covered with powdery material. Young pods affected become deformed, and powdery material also forms on their surface.

[Control] At the early stage of disease, spray 15% triadimefon wettable powder 1000- to 1500-fold solution, or 20% triadimefon emulsifiable concentrate 2000-fold solution.
