GROWTH POTENTIAL, PRODUCTION AND NUTRITION CONTENT OF INDIGOFERA ZOLLINGERIANA PLANTED UNDER THE OIL PALM PLANTATION IN JONGGOL BOGOR, INDONESIA

摘要

Indigofera zollingeriana has a huge potential as an alternative livestock feed and this plant is able to grow under low-intensity light conditions. The purpose of this study was to determine the relationship between the growth potential and nutritional content of the plant I. zollingeriana planted in palm plantation stacking rows (5 years old). This study was designed using a randomized groups design. The treatments consisted of two factors: the Indigofera treated with oil palm empty fruit bunches (EFB) (I+T) arid Indigofera without EFB (I). The treatments were repeated in triplicate and six experiment units. The variables observed were the morphology (plant height, number of branches, and trunk diameter), production (fresh and dried biomass per plant), and nutritional content (crude protein, crude fat, crude fijper, and gross energy). The results of the study revealed that oil palm empty fruit bunches had a significant effect on the plant height (cm), trunk diameter (cm), and number of branches atI+T (303.7±24.5 cm/plant), I+T (5.38.+0.06 cm/plant), I+T (73.6±11.3 branches/plant), respectively. The content percentage for crude protein, crude fiber, and crude fat in plants treated with oil palm empty fruit bunches were, respectively, 11.07 %, 2.12%, and 9.97%. It can be concluded that all the growth variables, namely heigh|, diameter, and the number of branches varied. Plant height, number of branches, and the trunk diameter were influenced by the EFB treatment and oil palm canopy shade. I.zollingeriana can be cultivated under oil palm stand with the oil palm empty fruit bunch treatment and would grow to be more productive and have a high nutritional content.
