Abstract:

We compared the agronomic character,yield and quality for Zhonghuang 30,Tiefeng 31and Tiedou 37 under different fertilizer levels and planting densities(12.0，16.5，21.0×104 plants·ha^-1)，Results showed （ⅰ） the seed yield varied with plant density significantly and got highest underplant density of 21.0×104 plants?ha-1, while was not significant under different fertilizer level;（ⅱ）Seed protein and oil varied with fertilizer levels and planting density, protein content of Zhonghuang 30 and Tiedou 37 was improved, while seed oil was decreased under middle fertilizer level and low plant density;（ⅲ）The protein content was improved for Zhonghuang 30 and Tiefeng 31in middle fertilizer level and middle plant density.The seed oil concent was decreaesed for Zhonghuang 30 in the treatment of fertilizer and the seed oil concent was improved for Tiefeng 31and Tiedou 37 in middle plant density;（ⅳ）The seed protein concent was improved for Zhonghuang 30 and Tiedou 37 in the treatment of fertilizer and high plant density. The seed oil content was improved for Tiefeng 31in the treatment of fertilizer.
