Abstract:

To enrich the suitable forage species in Shandong, this paper reports the observations on the growth traits, yield and quality of five Pennisetum varieties which were introduced from south China and planted for two production cycles from 2019 to 2020. The comprehensive evaluation was conducted with grey relational analysis to identify the most suitable varieties in this region. The results showed that the ratio of leaf/whole plant, the ratio of stem/whole plant and the ratio of leaf/stem of each crop of forage grass among the tested varieties were significantly different, and the plant height was not obviously different. The leaf/whole plant ratio and leaf/stem ratio of Pennisetum purpureum ‘Red' (RED) were the largest, and the stem/whole plant ratio of P. purpureum× P. glaucum ‘Reyan No.4' (RY4), P. purpureum ‘Guiminyin' (GMY) and P. purpureum ‘Guimu No.1' (GM1) were relatively high. The average yield of fresh and hay grass of the tested varieties were 120.36 and 20.20 t/hm2 respectively, and the fresh grass yield and hay yield of GMY, P. sinese (JJC) and GM1 were higher than those of other tested varieties. The results also showed that the CP content of each crop of forage grass of the varieties was higher than 11%, but the difference was not significant (P>0.05), and the content of NDF, ADF and ADL were also not significantly different among the varieties in most crops (P>0.05). The grey correlation analysis results indicated that GM1, GMY and RED had better comprehensive performance in yield and quality, and were suitable for promotion in this region.
