How is Betel leaf cultivated?

Believed to be native to Singapore and Malaysia, the betel is a climbing plant. Betel leaf is also cultivated in Kerala.

Well-drained, fertile soil is suitable for betel cultivation. It can also be grown as an intercrop in coconut and areca nut plantations. There are two main growing seasons, May–June and August–September.

What is the ideal soil and preparation method for Betel cultivation?

The ideal soil is fertile, well-drained, and rich in organic matter. Planting beds can be prepared by making mounds and adding compost, powdered cow dung, and slaked lime.

In one cent of land, 30 to 40 beds can be made. The beds should be one metre apart. Pits two feet wide and one foot deep should be dug, and dry leaves should be burned in them. Before planting, 50 grams of slaked lime and 50 grams of neem cake should be added and watered.

How are Betel vines used for planting?

The stem of the betel vine is used as the planting material. The vines are classified according to their age as Kunjikkodi (six months to 2 year-old vine), Ilamkodi (2 to 3 years), and Muthachikodi (3 to 5 years).

From these, healthy stems are cut from the top, all their leaves are plucked off, and vine cuttings with four nodes each are used as planting material. They should be planted in the prepared beds with two nodes buried underground. In each pit, four or five stems can be planted around a small support stake.

How should Betel vines be maintained?

The bed should always be moist. It should be watered twice a day. Tender leaves will begin to appear within 10–15 days. These can be tied to the supports with a rope.

Coiling the vines results in many stems and shoots. To do this, detach the betel vine from the initial small support, pluck off all leaves except the tender ones, coil each vine in the bed, and tie it with banana fibre. A new tender stem will grow from each plucked leaf node.

When and how are Betel leaves harvested and sold?

Betel leaves can be plucked from the vine every one and a half months. They are sold in bundles of 20–30 for convenient handling. They can be wrapped in banana leaves and brought to the market in a basket woven from palm leaves for sale.

Export-quality betel leaves can fetch a price of 300 to 400 rupees per 100 leaves. Tirur betel leaf is prominent in North India and international markets.
