Comprehensive evaluation of production performance of nine alfalfa varieties in desert irrigation area of northern slope plain of Tianshan Mountains
[Objective]In order to identify alfalfa varieties suitable for cultivating in the desert area of the plain on the northern slope of Tianshan Mountains.[Method]The single factor randomized block design was used to deter-mine the plant height,grass yield and quality of nine alfalfa varieties. The grey correlation method was used to com-prehensively evaluate these traits.[Result]With the increase in cultivating years,the dry and fresh grass yield of al-falfa showed a downward trend. The dry grass yield in the first year of alfalfa growth accounted for 37.77％ on aver-age. The maximum plant height accumulation of Baimu 341 was 939.76 cm,which was significantly higher than that of other varieties. The total hay yield,crude protein content and relative feeding value of Knight T were the highest,which were 61602.03 kg/hm²,16.83％ and 119.16,respectively.The comprehensive evaluation results of grey cor-relation degree ranked from high to low as:Knight T＞Baimu 202＞Galaxie Max＞Adrenalin＞Baimu 341＞Baimu 371＞Survivor＞Baimu 401＞Concept.[Conclusion]The overall performance of Knight T was the best,thus it was recommended to be introduced and planted in the desert irrigation area of the northern slope of Tianshan Mountains.
