Abstract:
In order to get a better understanding of the effects of starter-N plus topdressed N on N accumulation,distribution and yield of soybean,a pot experiment was conducted with 5 different N application times under the rate of N 50 kg·ha-1:all N as basal fertilizer(A),all N as topdressing at R3/R4 stage(B,C),N 15 kg as basal fertilizer and 35 kg as topdressing at R3/R4 stage(D,E).Results are shown as follow:at R5 stage,N accumulation(NA)in leaves of E was 11.5% lower than A,yet NA in nodules of E was 36.6% greater than A,suggesting that a smooth N transportation was ensured by E.NA in roots and pods of E were 21.7% and 64.2% greater compared to A(P<0.05)respectively,indicating that N demand of seeds after R5 stage could have been met by starter-N combined with topdressing.NA in whole plant of D and E was 82.6% and 105% greater than A(P<0.01)respectively at R4-R8 stages.There was a significant positive correlation between NA in R4-R8 stages and soybean yield(r=0.795**),and the improvement of NA after R4 stage was very important in achieving soybean yield potential.Seeds per plant of D and E was 14.8% and 15.8% greater than A(P<0.01),respectively,and yield of D and E was 17.6% and 19.9% greater than A(P<0.01),respectively.
