| A field experiment was conducted to investigate effect of nitrogen, phosphorous, potassium, boron and molybdenum fertilizer on the yield, nutrient uptake and utilization of broad bean. The results showed that nitrogen, phosphorous, potassium, boron and molybdenum fertilizer had significant influence on yield and biomass and the yield increase percentage ranked N>P>K>Mo>B. Under N∶P∶K∶Mo∶B=1∶0.99∶0.86∶0.0043∶0.0023, the accumulation amount of N, P and K in shoot was 358.55, 42.07 kg·hm-2 and 206.34 kg·hm-2, respectively. Agronomic use efficiency of N, P and K was 11.19, 15.70 kg·kg-1 and 7.5 kg·kg-1, respectively. Fertilizer use rate of N, P and K was 19.35%, 18.49% and 19.35%, respectively. Physiological use efficiency of N, P and K was 57.82, 84.91 kg·kg-1 and 14.63 kg·kg-1, respectively. The nutrient requirement for the broad bean grain of one hundred kilogram was 4.9 kg N, 1.1 kg P2O5, 4.9 kg K2O, and N∶P∶K ratio was about 1∶0.22∶1.00. |
