Cassava leaf has a potential to be used as a protein source for animal feed. This research was conducted to determine the effect of fertilizer on protein content and yield of cassava leaf. Five cassava cultivars were planted at Sriracha Research Station. There were two fertilizer levels; no fertilizer application and application of fertilizer formula 15-15-15 at the rate of 100 kg/rai. Planting space was 1*1 meter apart. Cassava leaf was randomly harvested at 4, 8 and 12 months after planting. At 4 months, leaf protein content in all cultivars had increased with fertilizer application. Without fertilizer application, average from all cultivars, leaf protein content was 18.75 percent, whereas 22.45 percent was obtained with fertilizer application. Fertilizer had no effect on leaf protein content when harvested at 8 and 12 months, Fertilizer application had increased leaf yield in all cultivars and harvesting times. Leaf yields were different according to cultivars and harvesting times.
