Study on Nitrogen Application Rate for High-yielding Wheat

doi:10.3321/j.issn:1000-7091.2002.z1.038

Abstract

Abstract: Suitable nitrogen application rate was studied through plot trials with different varieties and locations,located trials with different seeding date and seeding rate,and high yielding technology demonstration.Results showed that the suitable organic fertilizer rate was 3 000 kg/667m ²,nitrogen rate was 12～14 kg/667 m ² and P 2O 5 rate was 6～8 kg/667 m ² for the mid yielding soil to maintain a high yielding level and improve the soil fertility.

Key words: Wheat, High yielding, N application rate
