Abstract: To select alfalfa varieties adapting in saline areas of the Yellow River Delta, a three-year field experiment of complete randomized block was conducted to compare the plant height and hay yield of 50 alfalfa varieties. The results showed that: the production performance of different alfalfa varieties were different, except that‘Sijiwang’could not grow normally; the varieties‘SR4030’,‘Zhongmu No.1’,‘55V12’, ‘Zhongmu No.2’,‘Magna 6’,‘agna 551’,‘Xinmu No.2’and‘Lumu No.1’had higher hay yield and plant height, and the above two indexes of‘SR4030’reached 20.53 t/hm2 and 76.50 cm, respectively; on the contrary, the hay yield and plant height of‘Longmu No.806’,‘Caoyuan No.3’,‘Dafuhao’,‘DLF- 194’, ‘Alfaqueen’,‘Aergangjin’,‘Alfaking’and‘Aohan’were lower. Overall, the hay yield and plant height of different alfalfa varieties decrease with the increase of stubble. ‘SR4030’ has the best production performance, and is most suitable for planting in saline areas of the Yellow River Delta, followed by‘Zhongmu No.1’,‘55V12’and‘Zhongmu No.2’.
