Betel leaf

Piper betle is originally native to Southeast Asia, from India, Philippines, Timor-Leste and Indonesia and Peninsular Malaysia to Indochina, Vietnam, Cambodia, Laos, Thailand, Myanmar and Bangladesh. . Its cultivation has spread along with the Austronesian migrations and trade to other parts of Island Southeast Asia, Papua New Guinea and Melanesia, Micronesia, South Asia, the Maldives, Mauritius, Réunion Island, and Madagascar. It was introduced during the Colonial Era to the Caribbean by Indian indentured immigrants.

The betel leaf is cultivated mostly in South and Southeast Asia, from India to Papua New Guinea. It needs a compatible tree or a long pole for support. Betel requires well-drained fertile soil. Waterlogged, saline and alkali soils are unsuitable for its cultivation.

In Bangladesh, farmers called barui prepare a garden called a barouj in which to grow betel. The barouj is fenced with bamboo sticks and coconut leaves. The soil is plowed into furrows of 10 to 15 m length, 75 cm in width and 75 cm depth. Oil cakes, manure, and leaves are thoroughly incorporated with the topsoil of the furrows and wood ash. The cuttings are planted at the beginning of the monsoon season.

Proper shade and irrigation are essential for the successful cultivation of this crop. Betel needs constantly moist soil, but there should not be excessive moisture. Irrigation is frequent and light, and standing water should not remain for more than half an hour. Dried leaves and wood ash are applied to the furrows at fortnightly intervals and cow dung slurry is sprinkled. Application of different kinds of leaves at monthly intervals is believed advantageous for the growth of the betel. In three to six months, the vines reach 150 to 180 cm (59 to 71 in) in height, and they will branch. Harvest begins with the farmer plucking the leaf and its petiole with his right thumb. The harvest lasts 15 days to one month. …

The primary use of betel leaf is as a wrapper for the chewing of areca nut, or in modern times, tobacco, where it is mainly used to add flavour. The practice is thought to have originated in the Philippines around 5,000 years ago, where the oldest remains of areca nuts and calcium from crushed sea shells have been found in the Duyong Cave archaeological site. It spread along with the Austronesian migrations to the rest of Southeast Asia, Taiwan, South China, and South Asia. It is unknown when or why betel leaves were first combined with areca nuts, since areca nuts can be chewed alone. While the practice of chewing betel leaf existed even before the common era, with attested references from at least the 3rd century CE, the ingredient mix (paan/betel quid) it was chewed with changed over time. Areca nut, calcium hydroxide and catechu were the historic ingredients, as referenced in texts from 9th century CE. Tobacco started to feature in the 20th century. The practice of chewing betel leaf is on the decline, and now quid consisting of tobacco, areca nut, and limewater, known as gutka, is more popular. In India and Sri Lanka, a sheaf of betel leaves is traditionally offered as a mark of respect and auspicious beginnings. …
