How is tobacco cultivated

Harvesting The signs of maturity and the method of harvest differ with the type of tobacco. Essentially, there are two methods of harvest: priming and stalk cut method. Priming In tobacco, generally, lower leaves mature first followed by upper leaves in regular ascending order.

Harvesting is done by removing a few leaves as and when they mature. This method of harvesting is known as priming. Cigarette and wrapper tobaccos are harvested by priming. Stalk cut method Cigar, cheroot, chewing, bidi and hookah tobaccos are harvested by stalk cut method. In this method, plants are cut close to the ground with a sickle and generally left in the field overnight for wilting.

Subsequent handling varies with the method of curing. The correct stage of harvest is when maximum number of leaves mature. Curing is a slow process of starvation phenomenon to produce dried leaf of suitable physical and chemical property attained by various regimes of ventilation, temperature and humidity control. At the completion of curing process, even though the leaf is dead in the biological sense, some active enzymes may be present.

The freshly harvested leaf may be grouped into three components, which are likely to change upon curing. The static group, dynamic group and nitrogen group are the three classes. The static group is less variable and consists of crude fibre, cellulose, hemicellulose, pectins, tannins etc.

The components include proteins, soluble nitrogen including ammonia, nitrates, amides and alkaloids. Major changes take place in the dynamic group, which is made up of sugars, starches and organic acids. Grading After curing, leaves are graded by sorting leaves into uniform lots according to body, colour and degree of blemish or damage. Most important elements of quality in FCV tobacco are colour, texture, size, blemish, strength, even burning with white ash and agreeable flavour.

All four transnational tobacco corporations have a strong narrative around tobacco farming supporting the case that this activity would increase livelihoods, strengthen communities, provide financially stable futures for farmers, and good working conditions.

The COVID pandemic has worsened the struggle of farmers to find fair prices for their tobacco bales on the auction floors, as well as the health risks of tobacco farming. In Malawi, farmers have reported receiving less than half of the expected rate for their tobacco leaf at auction.

Tobacco leaf production has many environmental and health risks, which are frequently underreported by the tobacco industry. Minimizing the health and environmental impacts of tobacco growing is yet another tactic of the tobacco industry. Children are more vulnerable to green tobacco sickness given their proportionally lower body mass to nicotine absorption.

British American Tobacco BAT reported several cases of green tobacco sickness in its Brazil farm works, despite their having worn protective equipment. The risk of exposure to pesticides is higher in LMICs, given that the regulations allow more extensive use of these chemicals than in high-income countries. Pesticides are often sold to tobacco farmers without proper packaging or instructions. The health effects that derive from chronic exposure range from birth defects and tumours to blood disorders and neurological diseases.

The tobacco plant is in the same botanical family as tomatoes, potatoes, chili and egg plants. It integrates well into environmentally friendly crop rotations, benefitting subsequent crops like maize, rice etc. There are about 10, — 12, tobacco seeds per gram — it looks rather like powdery coffee.

The seeds are so small that they have to be nurtured in specially protected seedbeds for 60 days before transplanting to the field. A couple of weeks after transplanting, soil is cultivated and built up high ridge along the row for protection and to let them develop a good root system. As the plants grow, the farmer provides appropriate nutrition and watches out for pests. In a few countries the crop is mechanically harvested, but more typically the farmer will harvest by hand over two months, taking off two to four leaf per plant as they ripen.

Curing is a carefully controlled process used to achieve the texture, colour and overall quality of a specific tobacco type.

During the early stage of curing, leaf starch is converted into sugar, and the tobacco changes colour from green to lemon, to yellow, to orange to brown, like tree leaf in autumn.

Air-curing: Air-cured tobacco, such as Burley, is hung in unheated, ventilated barns to dry naturally until the leaf reaches a light to medium brown colour.
