China's 'father of rice' throws doubt on Indian record holder

A hybrid rice developer in China has called into question an Indian farmer's contention that he had harvested 22.4 tonnes of rice on one hectare of land, breaking a world record of 19.4 tonnes set by the Chinese scientist, reported the state-run China News Service on Thursday.

Sumant Kumar, a young farmer in the Nalanda district of India’s poor state Bihar, said last year that he achieved the record yields by using a method called System of Rice Intensification (SRI). Farmers using the herbicide-free method have reported higher yields with fewer seeds and less water and chemicals, according to a report by The Guardian.
