The cotton plant
Cotton is a shrub of the genus Gossypium in the mallow family.
It has a great desire for sunlight and requires approx. 200 frost-free days for the fruit to ripen. For adequate growth more than 500 mm of precipitation per year is required.
Out of over 290 varieties, reaching a height of up to 300cm, all but one, the less important indian Gossypium arboretum, are one-year. Consequently the crop needs to be planted every year.
Only three varieties of cotton are common. It is noteworthy that the length of the fiber (staple) is of special importance when evaluating the quality.
This variety, predominantly grown in Egypt, Sudan, Peru and the USA produces 3-4% of the world’s harvest.
It has a very long staple ( 29 bis 34 mm) and is being used for the production of finest yarn for fabricating high-quality textiles.
Most commonly grown (USA, Brasil, Pakistan, Turkey, former USSR) and most important variety with a medium staple (25 bis 28 mm).
Grown in Pakistan, China and India, has a short staple (under 25 mm).
