Effects of Cutting Times on Yield and Quality of Different Forage Grasses and Alfalfa Varietiesl

The yield and quality of different forage grasses and alfalfa varieties in different cutting times were studied in this trial.The results indicated the suitable cutting period of alfalfa was earlier flowering stage, and grass and hay yield in the stage were highest;the suitable cutting period of forage grass was flowering stage.Grass and hay yield of different alfalfa cultivars had no much difference significantly,while higher than yield of forage grasses.Crude protein yield of alfalfa was highest when cutting in squaring stage and crude protein of forage grasses was highest in flowering stage.Crude fat yield of alfalfa was highest when cutting in earlier flowering stage and crude fat of forage grasses was highest in multi-flowering stage.And in same cutting period,crude protein and crude fat yield of alfalfa were higher than forage grasses.Comprehensive evaluation from vield and quality,FGC-301 and FGC-201 in alfalfa varieties and awnless brome were adanted in Hobbot.
