1. Local name: Kacang Panjang (Vigna sinensis)

2. Planting:

Soil Preparation:

Field planting	Plough and loosen the soils at 15 cm to 22 cm (6 - 9 inches) deep to allow good growth of the root. Prepare the bed with 1.2 m (4 ft) in width, 25 cm (10 inches) in height and the length will depend on the area condition. The spacing from 1 bed to another is 60 cm (2 ft). Mix the soils of 100 square metre area with 50 kg of chicken dung.
Pot Planting	Mixed soils ( 3 parts of soils, 1 part of chicken dung and 1 part of sand) can be used. Put the mixed soils into the pot until 5 cm from the surface of the pot.

Planting:

Field planting

Plant 2 seeds in 1 planting hole, in 2 rows with spacing between rows is 60 cm (2 ft) and 45 cm (18 inches) between 1 planting hole to another.

When the seedlings growing, leave only 1 plant in 1 planting hole. It is about 70 gm seeds needed for 100 sq m (1000 sq ft ).

Pot Planting

Plant 2 seeds by 2.5 cm ( 1 inch ) deep. After 2 weeks planted, leave 1 plant only in 1 pot.

Preparation of stake:

Field Planting

Support the 3-week old seedlings with the stake of 2 m (6.5 ft) long. Place the stake slanting and opposite to each other and tie the top part. Place the sticks on top of the slanting stake horizontally in order to join them together. Ensure that the seedlings will coil round the stake.

Pot Planting

Use the stake of 2 m (6.5 ft) long. Ensure that the seedlings will coil around the stake.

3. Maintenance:

Watering:

Water the plant either in the field or in the pot every morning and afternoon (every day) except when it is raining.

Manuring:

Field planting	Apply NPK Blue Special (12:12:17:2) at a rate of 7 kg per 100 sq m (1000 sq ft). Baja ini dibahagi kepada 3 kali pembajaan iaitu pada minggu ke-2, 4 dan 7 selepas menanam.
Pot planting	Apply 1 teaspoon (5 g) of NPK Blue Special (12:12:17:2) per pot per week.

Weeding:

Need to be done all the time to avoid the plants to compete with the weeds.

4. Pest and Disease Control:

To control the fruit borer , spray the insecticide, like Carbaryl, 0.1% b.a.
For controlling anthracnose, spray with Mancozeb, 0.1% b.a.

5. Harvesting:

Field planting	The Ist harvest will be done 6 weeks after planting. Pluck the beans before it getting mature. Pluck once every 2 days in a period of 6 weeks. Estimated yield is about 100 to 175 kg for 100 sq m with average price from RM4.00 - RM6.00/kg.
Pot planting	Estimated yield is 0.5 kg/plant.
