| Abstract: | An experiment was carried out to compare the yield difference between leaf-age diagnostic and conventional fertilization techniques,and the results indicated that leaf-age diagnostic technique could result in 3% yield increase more than conventional method.The application of 70.5 kg/hm2 of N,47.0 kg/hm2 of P2O5,and 23.5 kg/hm2 of K could lead to the highest yield,8 402.4 kg/hm2. |
