Research objectives were to investigate green manure species namely Canavalia ensiformis on yield, yield component and leaf color of rice (Oryza sativa L.) cv. Sangyodphatthalung. The experimental design was split plot design in RCB of which main plots consisted of 2 treatments of transplanting date i.e. 10 and 20 days after incorporation of biomass into the soil, whereas sub plots consisted of 9 treatments by using different rate of biomass (kg dm/rai) and application with rock phosphate, application with chemical fertilizer and application recommended chemical fertilizer i.e. 500, 1,000, 500+rock phosphate (500+RP), 1,000+rock phosphate (1,000+RP), 500+triple superphosphate (500+TP), 1,000+triple superphosphate (1,000+TP), 500+ammonium sulfate (500+AS), 1,000+ammonium sulfate (1,000+AS) and recommended chemical fertilizer (CF). The results of yield showed that significantly different with only sub plots, the treatment of 1,000+TP gave highest average yield of 404.2 kg/rai and highest average number of spikelets per panicle, whereas the leaf color were found significantly different both main plots and sub plots at 80-90 days after transplanted.
