The Study on the Variations of Nitrogen and Potassium Efficiencies With Different Wheat Varieties

Jia Yuehui et al (Beijing Agricultural College,Beijing 102206)  
Soil experiments were carried out with 8 wheat varieties supplied by Teaching and research section of wheat breeding in Agronomy Department in Southwest Agricultural University and planted widily in Chongqing. The results are following as: No significant variations were observed in N absorption efficiency among wheat varieties in low and high fertilization treatments, the difference among wheat varieties is in middle. N utilization differentiated obviously in 8 wheat varieties in variable fertilizer treatments. The K absorption and utilization efficiencies were obtained differently in wheat varieties in low.middle and high fertilization treatments. By the experiment conclusions, we would know XiFu 10 was worth of planting in modern Agriculture; XiFu 3 was able to well under the conditions of different fertilization
