I want to know the answer to the following question:
What percentage of  the countries's farm-able land is used for the major farming production crop in Burma?
All the background I'm provided with is that "Through collaboration with the International Rice Research Institute 52 modern rice varieties were released in the country between 1966 and 1997, helping increase national rice production to 14 million tons in 1987 and to 19 million tons in 1996.". Is that enough to answer the question?
