| Abstract: | Changes of hay yield and economic values were Studied.Preliminary results indicated that there were significant diffrence among hay yields of 31 different alfalfa,of all,Amerigraze 401+Z was the highest,its hay yield was 9516.48 kg/hm2; Coumbo was the lower.Comprehensive appraisal on economic value of 31 alfalf a showed that Ameriguard 302+Z was the first. |
