Abstract: A pot experiment with 3 potassium application levels,0,1.5 and 4.0 g/kg(K2O)was conducted at two temperatures to study the effect of potassium fertilizers on the growth and nutrient uptake of maize The results demonstrated that the growth of maize with 1.5 g/kg(K2O),especially at lower temperature,is better than the other two treatments The results also indicated that,at low temperature,potassium application improved K uptake by plants and too higher potassium application results in decrease of P uptake and content of maize plants.

Key words: Maize (Zea mays L), Potassium, Phosphorus, Temperature
