New record in Bihar thanks to SRI

Written by Nicola Piras last modified Dec 14, 2011 06:25 PM
Darveshpura, a village in Nalanda district, Bihar, the third most populated state of India, located in the eastern part of the country, has been theatre of an incredible success.

A young farmer named Sumant Kumar set a new record in rice production beating the existing world record held by the so called “Father of Hybrid Rice”, the Chinese scientists Yuan Longping. This latter managed to produce 190 quintals of paddy in a hectare by means of a hybrid rice (DH2525), while Sumant achieved the extraordinary yield of 224 quintal paddy per hectare adopting “the system of rice intensification" (SRI).

Sumant’s result is of great significance. But what makes it noteworthy is not the record itself; or better, it is not merely that. There is more, it is the method that Sumant has employed to gain his bumper yield – SRI – which makes his record so relevant. Several times, on the pages of our magazine, SRI has been presented as a promising alternative to conventional ways of rice production. Yet, notwithstanding its potentialities, many within the formal agricultural establishment have often neglected, when not denied, its ability to be a convenient system of cultivation.

This approach was developed in Madagascar in 1983 by the French Jesuit Father Henri de Laulanié. It is the result of a series of empirical experiments in rice cultivation that de Laulanié started in the 1960s in order to help local farmers to deal with the scarcity of external input. As promoters like to define it, SRI is the system by which you can “produce more from less”. There are six basic elements that characterize and differentiate it from common practices:

  1. Seedlings are transplanted at a much younger age;
  2. single seedlings instead of clumps;
  3. wider spacing in square pattern;
  4. no floated but moist soil;
  5. rotary weeding;
  6. increased use of organic fertilizer.

The application of these elements promises numerous advantages like higher yield, reduced requirement of seeds and demand of water.

But why such a simple method, which is supposed to drastically reduce farmers' dependence from external inputs, at the same time allowing more gains, has found so many sceptics among farmers and institutions?

What we have to keep in mind is that SRI has not to be considered as a fixed set of rules but as a general method that farmers have to adapt – rather than adopt – to their local realities. This is why many of its supporters talk of SRI in terms of 'work in progress', as an approach that farmers have to tailor to their specific local conditions. Whether SRI will give positive results will depend in great part on how farmers (with the support of institutions that will provide adequate infrastructures) will be able to adapt it. As Norman Uphoff, Professor Emeritus at Cornell University in Ithaca, New York, noted in an interview for the World Bank Institute, one of the main constrains in shifting to SRI is mental: ideas about getting more production with less input, or getting more rice reducing plants density seems to many farmers counterintuitive and refrain them to trust SRI.

For rice farmers, practices such as flooding the ground are considered as mandatory and indispensable to get a rich harvest. Moreover, SRI demands to change production techniques which are rooted in millennia of rice cultivation history. A shift to SRI requires first of all a change in mentality, and changes in mentality are probably the most difficult to accomplish. Even though SRI is already gaining more and more consensus, advocates can now count on Sumant's record as a representative example to promote the potentialities of this new methodology.

Please do provide details of the rice variety / varieties used by the young farmers to achieve these world record yields,

I should be easy to now aim for breeding varieties over the next decade - with yield potentials tending towards the 30 tons and upwards!

Dear Madan,
Your response to the report on a record yield with SRI methods suggests that you missed the point of the article, that these results are not based on a particular variety. When the same hybrid varieties that gave farmers in Darveshpura village yields of 19-22 t/ha were used in the same season on the same farms by the same farmers (same soils, same climate), their average yield was about 7 t/ha, one-third as much as with SRI crop and water management. The lesson from Darveshpura should be that we focus more on giving crops their optimal growing conditions, to get the most productive phenotypes from given genotypes. You should consider our website:

This claim that the Darveshpura yields were faked is made without any knowledge of the facts or circumstances. I would invite Bill or anyone else who has doubts about this report to contact me at for details and information, or to read the article on this in AGRICULTURE TODAY (June 2012) written with DRD scientists and the NGO worker who knows most about the local situation. That article was cut in half by the editors so a lot of data were left out, but I can provide that upon request.

Fisrtly, I apreciate to SRI, Sumant Kumar and his friends

Our experiments showed that cultivation with no chemical fertilizer no chemical pestiside gave varied yield from 8 to 17 tons per hectar. Mostly from 10 - 12 tons per hectar.

Mr Uphoff, can I get your detail information about Mr Sumant Kumar did when he got the excelent yield? What kind of organic fertilizer? Did he use bacterial fertilizer or some other kinds?

Thank you

Heru Hartanto
