Who invented Bt cotton in Pakistan?
The National Institute of Biotechnology and Genetic Engineering (NIBGE) was the first Pakistani institute to develop a Bt variety of cotton. Its researchers claimed they had inserted the Cry 1Ac gene into a Pakistani cotton variety, named FH 901, using technology and processes developed at NIBGE.
How long does Bt cotton take to grow?
about five months
Bt is also early maturing, flowering at three months and ready for harvest at about five months. Furthermore, Bt cotton is drought-tolerant. Magondu, Wachira and Mwai agreed that although cotton is generally a drought-tolerant crop, the Bt variety can survive on less rainfall than its conventional counterpart.
Is Bt cotton a failure?
Bt cotton is unlikely to work for more than a few years in India because it is fundamentally at odds with the agricultural and climatic conditions here. Insects are likely to develop resistance quite fast, making the variety useless in a few years.
Was Bt cotton successful?
Burkina Faso’s 2008 Bt cotton adoption was Africa’s largest genetically modified (GM) crop introduction principally for small farmers, and became its most celebrated success story.
Why cotton is important for Pakistan?
Cotton is the most important cash crop in Pakistan and cotton products export account for 55 percent of all foreign exchange earnings of the country. Nearly 26 percent of farmers grow cot-ton, and over 15 percent of total cultivated area is devoted to this crop, with production pri-marily in two provinces.
How much cotton is produced in Pakistan?
In seven years, Pakistan’s cotton production has dropped to an estimated 4.5 million bales (480-lb) in MY 2020/21, a decrease of 61 percent; area planted has dropped from 2.95 MHA to an estimated 2.2 MHA, a decrease of 25 percent for this same period.
What is rank growth in cotton?
rank. A term signifying tall, vegetative cotton growth; often a result of late planting, excessive nitrogen fertilizer, fertile soils, or excessive moisture. Rank growth often renders cotton plants more attractive and susceptible to late-season insects, more susceptible to boll rot, and more difficult to defoliate.
Where does cotton grow best?
Cotton is planted from March to June and harvested from August to December. Among the U.S. States, Texas is the largest producer, contributing approximately 40 percent of U.S. cotton production in recent years. Other top cotton producers include Georgia, Mississippi, and Arkansas.
What are the disadvantages of Bt cotton?
Bt crops have a few disadvantages as well:
- Bt crops are costlier than naturally grown crops.
- It can disrupt the natural process of gene flow.
- The pests might become resistant to the toxins produced by these crops and the crop production might decline.
What are the benefits of Bt cotton?
The important advantages of Bt cotton are briefly :
- Increases yield of cotton due to effective control of three types of bollworms, viz.
- Insects belonged to Lepidoptera (Bollworms) are sensitive to crystalline endotoxic protein produced by Bt gene which in turn protects cotton from bollworms.
What are advantages of Bt cotton?
Bt cotton contains genes from Bacillus thuringiensis that make the plant resistant to the cotton bollworm complex. This inbuilt insect resistance can lead to savings in chemical pest control and higher effective yields in farmers’ fields (9).
Which city of Pakistan is cotton growing Centre?
Cotton is grown on an area of 4.7 million acre in Punjab annually with a production of 7 million bales and lint yield of 700 kg/ha. Major cotton growing districts in Punjab include Rahim Yar Khan, Bahawalnagar, Bahawalpur, Lodhran, Multan, Khanewal, Vehari, Sahiwal, Muzaffargarh, Rajanpur, D.G. Khan and Faisalabad.
