Daftar Isi:
- Different three varieties of alfalfa and three type of Rhizobium, (a side for Rhizobium meliloti) affect to root nodule formation that will have an influence on the growth and yield quality of alfalfa. The rare presence of Rhizobium meliloti so it need to look for the other potential rhizobium to form root nodules of alfalfa. The objective of this research is to study the interaction of the three varieties of alfalfa inoculated with three type of rhizobium on growth and quality of alfalfa yield of the first cutting. The experiment was conducted using a completely randomized design (CRD) with factorial experiment in March to June 2012 in the Green House Laboratory of Forage and Pasture Feed Faculty of Animal Husbandry Gadjah Mada University. Data observed were analyzed by analysis of variance with a completely randomized design, and followed by Duncan's multiple range test at the level of 5%. Regression and correlation analysis were performed to determine the relationship between two variables to determine the effect of growth and quality of alfalfa yield. The results showed that various rhizobium inoculated on Multiking 1, Vernal and Common failed and the unable to form viable root nodules. Infact several physiological parameters such as growth and photosynthetic rate, net assimilation rate and relative growth rate, showed significant differences between the combination treatment. Generally indicates that all combinations of treatments have relatively high levels of khlorofil, value between 1 to 3.3. Dry weight of plants affected by leaf area and photosynthetic rate. Highest plant dry weight is Common inoculated with Legumes cover crop harvested at 7 weeks. The highest value of total N content of the leaves found in were of Multiking 1 inoculated Rhizobium multistrain. Quality nutrients such as crude protein, crude fat, crude fiber, ash content and energy digestibility Variety Multiking 1, Vernal and Common are not significantly different. In vitro digestibility of Multiking 1, Vernal and Common are not significantly different.
