Yard Long Beans Farming – Soil And Climatic Requirements:

The soil for the Yard Long Beans must be well-drained, fertile and the texture which is suitable is garden loamy. The pH of the soil should be 5.5 -7.5. They can even tolerate slightly acidic soil for cultivation. The waterlogging, or heavy rainfall is not at all a problem for the Yard Long Beans. These plants, even grow in soils like sandy soil and heavy clay soils very effectively. Many other varieties of the Yard Long Beans can also be grown in them. These also thrive in humid climates with heavy and consistent rain. These plants or plants never grow in cold climates. They only need a hot climate for growth. The temperature required for the cultivation of this plant is 18-35˚C

Land Preparation and Planting process in Yard Long Beans Farming:

Before digging the soil for the cultivation of Yard Long Beans, an application of 200 g/m2 of dolomite should be sprayed to the soil which is more beneficial. Seedbeds should be prepared for deep soil types. The drainage facility should be mounted for the seedbeds.

The seeds should be sown 2 cm deep down the soil in rows. The Yard Long Beans are planted 30 -50 cm apart from each other in a row.

The seed rate per hectare would be 10-30 kg of seeds.

Propagation Method in Yard Long Beans Farming:

In the NT (Northern Territory) the snake bean seeds do the best when they are sown in slightly damp soil with warm climatic conditions. We should not water until the seed gets germinated, the plant should also be mounted. They should be planted 3 m apart from each plant in a row. We should make sure that the soil is having high moisture content.


Yard Long Beans Farming – Manure And Fertilization Method:

It is known that the Yard Long Beans belong to the legume family and the development of nodules to the roots of the plant helps them to be capable of taking in the nitrogen from the air and supply it to the plant. But the plant gets limited nitrogen and there would be some additional requirement of the NPK mix which is also supplied to the plants.

The mixture of the fertilizer is such that 14N:14P:12K should be sprayed along the rows @ 70 g/m2.  And 50 mm of fertilizer should be added to the land from where the seeds are sown and the soil is covered.

The crop is again supplied with the ratio of 50:50 of urea and potassium sulfate mix of 5 g/m for each row every 4 weeks.

Yard Long Beans Farming – Irrigation Method:

Regularly, the water should be supplied to maintain the moisture level in the soil. The watering frequency depends on the soil and the moisture contained in it as the sand and clay soils absorb water soon and do not have enough moisture retention capacity, therefore, these soils need a regular water supply. And the watering also depends upon the climatic conditions.  Water stress cannot be handled by these plants, then the yield drops down considerably. For better control of water drip irrigation is good.

Yard Long Beans Farming – Weed Control Measures:

To prevent weeds hoeing the field should be done periodically. Application of pre-emergence herbicides can be used to control weeds.

Pest And Diseases Control Measures in Yard Long Beans Farming:

As the crop is sensitive soil-borne diseases can occur. The beneficial nematodes should be grown around the crops. And the soil should be solarised for 6-8 weeks before the planting.


Anthracnose, Bacterial Blight, Powdery Mildew, Root Rot, and Bean Mosaic Virus. These all diseases can be controlled by the application of IPM (Integrated Pest Management) principles and also we can use EPA-approved chemicals for the crop to protect them from diseases.


Bean fly, Pod borer, String bug, Thrips, Black Bean, Aphid, White Fly, and Red Spider Mite. These can also be controlled by applying IPM and EPC chemical compounds.

Harvesting  Techniques in Yard Long Beans Farming:

The fresh Yard Long Beans can be harvested in 70-90 days from planting. The fine and extra-fine beans can be harvested every day. The pods should be cooled to remove them from the field. And they should be packed in the ventilating boxes immediately after harvesting.

Fruiting Season Of The Yard Long Beans:

The harvesting of the Yard Long Beans is generally done in 8-10 weeks after the sowing. The flowering of the plants starts after 8 weeks from the planting season.

  1. Dear Mr. Reddy,
    Thanks for the information regarding Long Beans (Yard beans), but please recheck the information, which you mentioned regarding Yield for year from 1 hectare.

    we are producing more more and more from each hectare.

    Waiting for your Response.


    • Hello thanks for writing us. However, we have given lower side, I know the yield depends the variety plus cultivation practices. We have seen 30 tonnes per hectare as well. There is no such constant figure yield.
