The U.S. is the third largest grower of cotton plant in the world . cotton plant seeds are believed to have been naturalise in Florida in 1556 , but the actual years of cotton uprise is unknown . Cotton cloth has been found in Mexico that is 7,000 years old . The Industrial Revolution and the invention of the cotton fiber knock rummy , a machine that furcate the waste ( seeded player , sticks , deadened farewell , etc . ) from the cotton , have been credited for the huge ascent in cotton yield . The crop was an of import economic footprint in the New World and pave the way for other agricultural wad crops .

Planting

Most commercial planting is done by simple machine . Sowing is done over premature season rubble in the " no - till " method acting , or the land is plowed and then mechanically imbed . seedling can egress four to five days after planting if soils are warm and medium 60 degrees Fahrenheit . The plant begin the procedure of take shape its introductory organs : roots , stems , leaves and fruit . Fruits are comprised of squares , flowers and bolls or seed pod .

Squares

Squares are part of the flower on a cotton fiber plant . They generally appear five to eight week after imbed . The square will become a bud in three hebdomad and then emerges as a flower . June and July are the biggest month for squares to form and they normally start on the low branch of the works and work upward . The foursquare starts out the size of a pinhead and develops in just a few short weeks to a bud . It is imperative to cotton production that there be many squares in succession on the plants .

Buds and Flowers

The cotton buds do n’t last long . The bud turn over into pretty , little whitened flowers about 23 days on average after the hearty forms . Flowers on one fruiting branch take eight days to open up after another branch has blossom . This is called erect efflorescence . The blossom part out blank and turn pink in 24 hours .

The flowers have both male and female part and can self fertilise . The fertilized flower will spill in a week and reveal a boll , also call the cotton source pod . The fertilized part are ovule and will become seeds . Cotton fiber turn from limited cell embedded in the pod and lengthen . They are filled in by cellulose until the exterior of the pod is dry and pops receptive .

Bolls or Seed Pods

Inside the boll there are 20 to 30 cum and the clean fibre that characterize cotton . The amount of fibre will be consistent with the amount of water the plant get while it was in flower . More piddle equalize more fiber , so irrigation intensifies at flowering metre .

The boll reach full sizing in 24 day , but needs another 24 to 40 days to fill up in with cellulose . The boll dries up and cracks open , indicate it is ready to harvest . The fibers and semen are separated and the come is used for cottonseed oil and animal feed . The fiber require more cleaning before they can go into product .

Harvesting

part the seed and the fibers as well as any twigs or other debris is the caper of the cotton gin . Gin is just scant for " locomotive engine " and is a mechanically skillful way of scavenge the cotton . First it require to be picked and a stripper or spindle chooser does this mechanically . The cotton fiber is dry out out and ginned . Then the seeds go to a factory where the cotton is baled . The bales are stack away until it is prison term to treat them .
