Abstract：For researching the effect of nitrogen and potassium fertilizers on sweet sorghum ,some agronomic characters and sugar contents of sweet sorghum hybrid (Liao-tian 1) were determined under different fertilization methods .The result indicated that the plant height ,fresh weight and estimated total sugar content of sweet sorghum with the treatment of entire base fertilizer applica-tion of compound fertilizer 600 kg/ha were all the lowest of all treatments .The plant height and fresh weight of the treatment with compound fertilizer 300 kg/ha as seed manure and urea 300 kg/ha as topdressing were the highest of all treatments .In the filling stage ,the LAI of sorghum with compound fertilizer 300 kg/ha as seed manure and urea 450 kg/ha as topdressing was higher than other treatments in the experiment .Under the fertilization method of compound fertilizer 300 kg/ha as seed manure and urea 150 kg/ha and potassium sulfate 150 kg/ha as topdressing ,the es-timated total sugar content of sweet sorghum was the highest in the experiment .
