Komponen Dinding Sel Indigofera (Indigofera zollingeriana) di Lahan Gambut Berdasarkan Umur Panen 2, 3, 4 dan 5 Bulan setelah Pemangkasan

The purpose of this study was to determine the appropriate harvest age and the content of neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), hemicellulose and cellulose of Indigofera zollingeriana growth in sapric type peatlands based on harvest age of maturity (2, 3, 4 and 5 months) after pruning. Indigofera zollingeriana foliage was obtained from the existing plot that is a ± 3.5 year old that grows in the research farm of the UIN Agriculture Research and Development Station Laboratory, Faculty of Agriculture and Animal Sciences, State Islamic University of Sultan Syarif Kasim Riau. The research design used was a randomized complete block design (RCBD) consisting of 4 treatments and 4 groups. The treatments were: (1) I. zollingeriana biomass harvested at 2 months of maturity; (2) I. zollingeriana biomass harvested at 3 months of maturity; (3) I. zollingeriana biomass harvested at 4 months of maturity; (4) I. zollingeriana biomass harvested at 5 months of maturity. The results showed that the differences in harvest age of I. zollingeriana at 2,3,4 and 5 months after pruning did not significantly (P>0.05) affect the content of NDF, ADF, hemicellulose and cellulose. However, the increase in harvest age of maturity from 4 to 5 months significantly (P <0.05) increased the ADL content of I. zollingeriana from 6.02% to 12.37%. Based on the research data, it can be concluded that the cell wall components of I. zollingeriana in the form of NDF, ADF, hemicellulose and cellulose were relatively stable on sapric type peatlands with an increase in harvest age from 2 to 5 months after pruning. However, the ADL content increased significantly at the 5 months of harvest age of maturity.
