| Abstract | System of Rice Intensification (SRI) is a promising rice production technology that could enhance rice yield with environmental sustainability. However, there are potential threats and constraints reflecting to it dissemination prospective. The primary objective of this study was to explore the various factors influencing the dissemination of SRI to facilitate related recommendations for its greater improvement. The data for this study were obtained from focus key informant and related SRI implementing agencies and structured questionnaire surveys conducted in Tramkak and Dangtung district of Cambodia. Regression analysis represents that SRI yield is determined by (i) labor for weeding and management, (ii) number of irrigation provide, (iii) labor availability, (iv) age of seedling, and (v) total fertilizer use. Another regression model shows the factor influence to size of land allocation for SRI such as (i) labor availability, (ii) distance from house, (iii) number of contact with extension last year and (iv) land size holding. SRI technology lead significant decrease in farm input and extremely cut the bottle neck of labor for uprooting while there significant increase in Labor demand for weeding and management. SRI generally gets 16-30% increase in yield compared to conventional. The major obstacles for SRI practicing and its dissemination were draught, labor shortage, and availability of irrigation facilities. SRI shows a great potential for Cambodian farmers. Although constraints limit its use on larger proportions within a farm and certain farming households might not be able or willing to apply it, its potential should not be missed. |
