Cotton is machine harvested in the U.S., beginning in July in south Texas and in October in more northern areas of the Belt. Stripper harvesters, used chiefly in Texas and Oklahoma, have rollers or mechanical brushes that remove the entire boll from the plant. In the rest of the Belt, spindle pickers are used.
Although it is one of the species that is commercially cultivated as an annual field crop, most of the cotton (in excess of 90%) that is commercially grown in the world today comes from G. hirsutum, a New World species commonly known as upland cotton. Levant cotton needs a long hot summer.
