Introduction

 
FAQ
Can China's farmers increase grain yields?
Yes, quite a bit. It is estimated that current average grain yields of about 4.9 tons per hectare could be increased at least by some 15 to 30%.
An increase of grain yields would require improvements in agricultural management, better crop varieties, optimized input of agricultural chemicals, and the use of modern technology in cultivation, harvesting and harvest processing.
The International Rice Research Institute (IRRI) recently reported that in the Taoyuan township of temperate-climate Yunnan province farmers have been harvesting 15 or more tons of rice per hectare for the last 8 years. This was possible because they used a modern rice variety IR72 (IRRI news release) and high inputs of fertilizers.
