Pertumbuhan dan Hasil Tiga Varietas Alfalfa (Medicago sativa L.) dengan Perlakuan Tiga Macam Rhizobium pada Media Tanam Regosol Asal Banguntapan
ABSTRACT: Different alfalfa
varieties type of Rhizobium (a side of 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 other
potential rhizobium expected to
form root nodules
of alfalfa. The purpose
of this research is to study the interaction of the three varieties of alfalfa inoculated with different type of
rhizobium on growth and quality of alfalfa yield of the first cut.
The experiment was conducted using a completely randomized design 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 measurements and observations were done on growth parameters and the
quality of the results and were analyzed by analysis of variance with a
completely randomized design, and followed by Duncan's multiple range test
level 5%. Regression correlation analysis 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. 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. 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. Nutritional quality and in vitro digestibility of Multiking1,
Vernaland Common are not significantly different.
Keywords: alfalfa varieties,
type of rhizobium, growth, quality of yield, and in vitro digestibility
