The focus of discussions between Cambodia’s senior agriculture officials and scientists from the International Rice Research Institute (IRRI) at IRRI headquarters recently was to help Cambodia find ways to considerably increase its annual rice production in the next 10 years. “The most important priorities for the country right now are the seed systems and varieties that can adapt to drought, flooding, and other stresses caused by climate change,” said Mr. Ngin Chhay, director of the Department of Rice Crops at the General Directorate of Agriculture of Cambodia.
Dr. Abdelbagi Ismail, the torch-bearer of the Stress-tolerant Rice for Africa and South Asia project, briefed the officials on educating smallholder farmers in Cambodia on “Accelerating the Adoption for Stress-Tolerant Varieties (ASTV).” Dr. Abdelbagi, who is leading this project supported by the United States Agency for International Development, said that “IRRI is pursuing this opportunity because of the success and impact these climate-resilient rice varieties had in South Asia.” He further added, “Our hope is to repeat this success in Cambodia and see how these varieties can really make a difference for farmers’ livelihoods and food security in the country.” He stressed, “We also want IRRI’s assistance in developing integrated pest management approaches and implement these within the country.” He lamented the fact, “Cambodian farmers commonly misdiagnose some rice diseases and often use chemical control ineffectively.”
To facilitate the distribution of seeds and the targeting of appropriate varieties to specific environments, IRRI is conducting the Remote sensing-based Information and Insurance for Crops in emerging economies (RIICE) project in the country. “In RIICE, we monitor the rice areas every season,” said Dr. Nasreen Khan, head of the GIS lab at IRRI. “We use radar technology that can penetrate clouds. Every 12 days, we get satellite images to help analyze and map rice production areas. The project also provides estimates of yields in the middle and the end of the season for local monitoring.”
IRRI’s agronomist, Dr. Yoichiro Kato, stressed the importance of crop and nutrient management practices for increasing productivity. “Besides improving the seed systems and developing new enabling policies, we also need to improve farmer’s management practices to maximize rice production,” he noted. Over the past 7 years, IRRI on-farm demonstrations across 192 sites showed that rice farmers can harvest an additional tonne when new varieties are combined with best management practices on nutrients and pest control leading to the increase in farmers’ net income. The IRRI-led Ecologically-based Participatory IPM Package for rice in Cambodia project aims to develop site-specific, environment-friendly integrated pest management (IPM) packages for rice farmers in the country.
Postharvest management and technologies are also critical to Cambodia’s goal of becoming a major rice exporter. “Postharvest issues are playing an increasingly important role in Cambodia,” said Secretary of State H.E. Ty Sokhun of the Ministry of Agriculture, Forestry and Fisheries. “We still command a competitive price at the farm level, but our concern is transportation and processing.” Engr. Martin Gummert, IRRI postharvest and farm mechanization expert, shared an overview of how IRRI has been working with Cambodian farmers and industry leaders on different postharvest technologies since 2005. Some of the technologies that have been introduced include combine harvesters, flatbed dryers, laser levelers, hermetic storage systems and others.\
