|
Alley cropping field experiment has been carried out for 24 months in lime-stone based dryland farming area of southern Bali to study the chemical composition and nutritive value of 16 provenances of Gliricidia sepium. The design was a completely randomized block arrangement, consisted of 16 treatments(G. sepium provenances) and 6 blocks as replications with 12 plants per provenance. Of the 16 gliricidia provenances, six were from Mexico(M), four were from Guatemala(G), one each was from Colombia짤, Indonesia(I), Nicaragua(N), Panama(P), Costa Rica짰 and Venezuela(V). After 12 months establishment, the gliricidia were lopped at 150 cm height regularly 4 times a year, twice during the 4 months wet season and twice during the 8 months dry season. The highest ash, mineral, total soluble phenol, prussic acid and digestibility were in V1; the highest crude fiber component was in M39; the highest gross energy was in P13, while the highest organic matter was in M35. Based on the highest nutritive constituents, V1, C24 and G14 were ranked first, second and third respectively, while based on the lowest non-nutritive constituents C23, V1 and N14 were ranked first, second and third, respectively. The importance of such provenances as source of nutrients for the ruminant during the dry season were discussed. |
