Abstract: An experiment is carried out that effect of N application at different rates on grain yield and qual-i ty of two wheat varieties under the totaLpure N 240 kg/hm2.The results indicate that increasing N application rate can enhance grain yield and quality but there are different between two wheat varieties.Little base N and more application N at jointing stage increase grain yield and improve development time, value and curve area sig-nificantly for mul-i spike type wheat variety.Increasing N application has little effect on grain yield of large-spike variety.Keeping more base N and little application N is benefit for large-spike variety increasing grain yield and improving quality.Considering grain yield and quality, base N 50% and application N 50% or base N 30% and application N 70% is suitable for mul-i spike variety.In the meantime base N 70% and application N 30% is suitable for large-spike variety.
