ABSTRACT
This research was aimed to evaluate the productivity of native pasture
in Timor Island by introducing various palatable species. The study was carried
out on native pasture in Tuatuka, Timor Island for seven months. The study was performed by using
randomized block design (RBD) with eight treatments (S0: no introduction, S1: Cynodon dactilon, S2: Dicanthium aristatum, S3: C. plectotachyus, S4: Brachiaria decumbens, S5: Desmanthus virgatus, S6: Macroptilium atropurpureum, S7: Clitoria ternatea) with four replications. Procedures on this study include
trial plots preparation, tillers preparation for each species, introduction of
species in trial plots, maintenance and observation of the productivity.
Variables observed were forage production (fresh and dry matter (DM) in ton/ha), nutrient
content (%) and stock capacity (animal unit (AU)/ha). Data were analyzed for variance based on
RBD and followed by Duncan’s test. Analysis of variance showed that
introduction of species had a very significant effect (p < 0.01) on
all observed variables. The introduction of M. atropurpureum produced the highest
fresh forage (2.1 t/ha) and DM production (0.69 t/ha). M. atropurpureum also had the highest DM content (43.61%), nitrogen free extract
(52.52%) and stock capacity (1.06 AU/ha). The highest crude protein and crude fiber content were found in D. virgatus (4.31% and 36.62%).
The highest extract ether was observed in D. aristatum (1.48%). No
introduction had the lowest productivity, but demonstrated the highest ash
content. The introduction of palatable species increased the productivity of
native pasture in Timor and M. atropupureum was the best
introduced species.
