Indian farmer sets new world record in rice yield

MANILA, Philippines – Indian officials have confirmed a farmer’s claim of beating the rice yield world record of 19 tons per hectare previously held by hybrid rice developer Yuan Long-ping of China.

Sumant Kumar, a rice farmer from India’s state of Bihar who uses a new rice-growing method called the System of Rice Intensification (SRI), reported a harvest of 22.4 tons (448 cavans) per hectare last November. His claim was confirmed in a verification visit by Bihar State agriculture officials, including the agriculture director, the official in charge of national food security, “a team of agriculture experts”, and the Nalanda district agriculture officer, who said, “the team found the claims true.”

Sumant’s neighbors got slightly lower yields, but still ahead or at par with the previous world record. Rice farmer Krishna Kumar got 22 tons, Nitish Kumar 19.6, Ramanand Singh 19.2 and Sanjay Kumar 19 tons. All used the SRI method. Almost 90 percent of rice farmers in the Nalanda district are already using SRI, district agriculturist Sudama Mahto said.

    Kumusta All,
    You don’t hear much from me lately , but I am here and intensifying grain with the SRI approach in US. people here cannot yet appreciate the importance of this and maybe will never do so till too late. I am very pleased to see progress world wide on this effort and even more pleased that it is small holder farmers, both men and women of many race and nationality doing the best with this. Small farms and observant farmers are the seed places of great discoveries for future world needs and indeed foundations of peace, where hunger is displaced by nutrition and skills at repairing soils and enhancing the potential of crops.
    right now , my work is to apply the wonderful inventions of TM Ismahoon from Thambutagama, Sri Lanka.
    A builder of small affordable and efficient threshing machines capable of rice , corn, beans and every grain in between. Also solar dryers for fish, fruits, vegetable and grains.
    Intensified tools that can follow the intensification methods of growing crops is an identified need everywhere.
    I will post more as time permits.
    another topic I will write about soon is the radioactivity fallout from Fukushima and ways to protect ourselves , food and water. the problem will not diminish or go away in our lifetimes.
    best regards, M

    Hybrid rice nga ang ginamit ni Sumant Kumar. Pero hinati nya ang bukid nya sa dalawa, yung isa SRI, yung isa pa, hindi SRI (dating gawi). Parehong hybrid variety ang ginamit nya sa dalawa. Sa SRI, 22.4 tons/ha ang nakuha nya. Sa hndi SRI, 6.5 tons/ha lang. Ibig sabihin, hindi yung variety ang importante kundi yung paraan ng pag-aalaga.
