| Abstract: | An optimized regression design with three factors and five levels was adopted to study the effects of N,K and S fertilizers on the yield and nitrate content of radish.The optimum combination of three fertilizers is N 180~200 kg/hm~(2) (K_(2)O) 120~150 kg/hm~(2) S 135~160 kg/hm~(2),which can get higher yield of radish with a low content of nitrate. |
