India is one of the main wheat producing country . After the Green Revolution in the 1970's and 1980's the production of wheat has shown a huge increase. The major States that are involved in the cultivation of wheat are those located in the plains like Uttar Pradesh, Punjab and Haryana. They account for nearly 70 per cent of the total wheat produced in the country. Punjab and Haryana yield the highest amount of wheat because of the availability of better irrigation facilities. The production of wheat in other States like West Bengal, Kerala, Assam, Odisha and Andhra Pradesh has grown with the provision of better irrigation facilities in the area.
