12 Cassava Varietal Improvement Objective: - High root yield/ high starch yield in form of dry matter content - Early harvesting - Adaptation for unfavorable condition - For human consumption - Resistance CBB, brown leaf spot, root rot, red mite and termite - Good plant type suitable for cultural practice and harvesting

13 collection, introduction hybridization seedling selection clonal selection preliminary yield trial standard yield trial regional yield trial farmer’s field yield trial farmer’s field test variety recommendation (seed) Figure 1 Flow chart of cassava varietal improvement (cuttings)

17 Cultural practices - Land preparation - Planting methods, spacing - Planting times and age harvest - Weed control - Cassava stem storage - Fertilization and soil conservation

18 Pest and diseases Fortunately, Thailand has not experienced any serious pest and diseases infestation in cassava. - Cassava bacteria blight (CBB) - Cassava brown leaf spot, root rot - Red mite, termite, white grub

19 Farmer participatory research and extension (FPR & FPE) The use of FPR & FPE showed that farmers become more aware of the importance of soil conservation. The most appropriate methods of soil erosion control were selected by farmers and tested their own fields to develop the most suitable practices for their own conditions. It was very effective in developing more suitable varieties and production practices which farmers could readily adopt and then disseminate to after farmers in neighboring communities.

20 Cassava leaves as animal feed - Protein content % - Harvest every 2-3 months for 1 year could produce dry foliage varied from 4-12 t/ha - Good profile of amino acid as compound with soybean meal and alfalfa hay - Increase the milk thiocyanate content could enhance milk quality and milk storage

21 Vision and Development Strategy of Thai Cassava 1.The whole of fresh root yield go to produce chips and pellets of 50% and to produce starch of 50% 2. To establish cluster of Thai cassava 3.Government maintain the high price 1.50 baht/kg of fresh root for farmers 4.Remain farmers ’ income oriented policy 5.To change using high yield varieties 6.Short term target yield at t/ha medium term at 31 t/ha 7.Starch export would continue to expand world wide especially in Asia countries 8. Ethanol production for domestic use
