Thailand's cassava production for 2569/70 shows planted area expanding 2.29% to 6.766 million rai (driven by attractive prices), but per-rai yield declining 1.32% to 2.77 tons/rai, limiting overall production growth to just 0.94%. Key constraints include acute shortage of quality planting material, widespread leaf spot disease spreading across northern and northeastern regions, and early harvesting by farmers facing liquidity pressures—collectively undermining productivity gains and starch content efficiency.
