Field study on the adoption/adaptation of SRI technqiue

On 03-04 March 2009, Mr. YIM Sok Sophors conducted a field study on adoption/adaptation of SRI (System of Rice Intensification) in Thnoung village, Sdao Koang commune, Baphnom district, Prey Veng province, Cambodia.

The study aimed to know about the changes of farmers' practices in term of rice production in the village, especially to see the differences before and after the intervention of CEDAC's project in that studied village. It is to note that this study is only a part of the whole study on SRI in 20 villages within CEDAC's target villages. 10 farmers including the chief of village based farmer association and its members as well as the non SRI farmers were also invited to join the group discussion. To seek for more detail information, seveal farmers were in-depth interviewed.

Based on the result of this study, it is able to know that some techniques of SRI have been adapted by the villagers such as:
  1. 80% of the farmer families in the village have reduced the amount of rice seed for broadcasting on the seedbed. 22% of seed quantity is reduced as the previously used 57.5 kg/ha and it is now only 45 kg/ha.
  2. The age of seedling is also reduced according to the rice varieties
  3. The number of rice stem per hill is also reduced from averagely 6 stems per hill but it is now only 3 stems per hill
  4. Farmers have tried to make further compost of supplying to their rice fields. The average amound of compost is increased from 1750 kg/family/year up to 2425 kg/family/year.
  5. The rice yield is also increased from 1.1 t/ha before the project's intervention up to 1.87 t/ha at the current time.
However, there are some techniques that farmers have not wildely practiced, such as:
  1. The size of seedbed, but they just improve the preparation
  2. Uproot only healthy seedlings for transplanting
  3. Transplanting in row and equal from one hill to another
  4. Transplanting immediately after uprooting
  5. Weeding, water management, soil leveling are not widely adapted,
In short, it is able to conclude that farmers have adapted the techniques of SRI that enabled them to increase the rice yield significantly. However, there is a need of effort in order to mainstream other techniques of SRI to the farmers in the communities.
