Pest control is a major challenge for both commercial and smallholder farmers in Cambodia. Many pest problems have evolved and one of the more serious ones is a growing pest resistance to the plant protection products currently on the market. By adding adjuvant to plant protection products, farmers can reduce the amount they use, lower production costs, minimise harm to the environment, and increase their yields.
Cassava farmers use traditional growing practices learned from their neighbours and communities. Changing the use and timing of fertiliser application can improve yields, but cassava farmers in Cambodia are seen as a small market, so fertiliser companies haven't invested in delivering information services.
Cambodia wants to increase rice exports - especially the fragrant varieties that can compete internationally with the Thai rice varieties. The Sen Kra Ob variety competes well in the export market, has high yields and can produce two, or in some cases, three crops per year.The problem is that there are too many versions of the seeds distributed by seed producers and millers.
Many farmers in Cambodia lack knowledge about pest control and often have trouble identifying the pest and selecting the best remedy. Pest control became very topical in 2010 due to uncertainty around pesticide policies, especially related to imported products. There were new companies entering the market and CAVAC saw an opportunity to both benefit the farmers and improve the sales of pesticide companies.
Cambodian cassava farmers have limited knowledge about how they can improve their yields with fertiliser and pesticides. And because rice is the dominant crop in Cambodia, agricultural input companies have had little incentive to target cassava farmers with their marketing outreach and information services.
AQIP Seed Company, a semi private organisation, is the largest rice seed producer in Cambodia. But further growth of AQIP as a private company is hampered by limited access to capital, lack of much needed investment in processing equipment and storage, and sufficient management and marketing skills.
Because of labour shortages, rice farmers in Cambodia have abandoned transplanting and broadcast their seeds by hand. Farmers that manually broadcast use very high seed rates of 150 to 400 kg per hectare. This is not only costly but also makes it impossible to build a sustainable seed supply system.
Cassava has become Cambodia's second largest crop after rice, and production volumes are increasing year by year. Although national production is increasing overall, many smallholders who continue to use traditional methods are experiencing a decrease in yields.
Mr. Keo Leam is broadcasting rice seed in one of his rice fields. After attending a demonstration with Lay Seng company, he has increased his yield from 6.5 tonnes to 8.23 tonnes and reduced the production cost.
