Record-high rice yields reported in Hainan

Xie said the measurements included weight of the new rice grain, water content, acreage and extraction of impurities.

He said the harvest was part of a "double cropping" hybrid rice project launched in Hainan in December last year. It targets the combined early and late reaping with a yield of 1,500 kg per mu. Yuan Longping, who was also academician of the Chinese Academy of Engineering, was the chief scientist for the project.
