Abstract
ABSTRACT
The study was conducted in Babulu District, North Penajam Paser Regency, East Kalimantan, on acid soil (pH = 3.77), with dusty sandy soil texture. The land was not cultivated but only cleared and experimental plots were made, with a dose of 10 tons/ha of manure and 4 tons/ha of dolomite.. The three types of Banggala grass as treatments (Panicum maximum cv Hammil, Panicum maximum cv Riversdale, and Panicum maximum cv Purpleguenea) were planted as intercrops between palm trees, in each plot measuring 6x15 m2, with a spacing of 1x1 m2. The research design used a Randomized Block Design (RAK), and each treatment received 10 replicate plots. The observed variables were biomass production, leaf, stem, leaf/stem ratio, and forage quality (CP, CF, energy, Ca, and P). The results showed that the fresh biomass production of Panicum maximum cv Hammil was significantly higher than Panicum maximum cv Riversdale, and Panicum maximum cv Purpleguenea. Fresh leaf production of Panicum maximum cv Purpleguenea was significantly higher than Panicum maximum cv Hammil and Panicum maximum cv Riversdale, However, the production of fresh stems of Panicum maximum cv Hammil was significantly higher than the two, so that the highest leaf/stem ratio was achieved by Pannicum maximum cv Hammil. The crude protein of Panicum maximum cv Riversdale was significantly the highest, but there was no difference between Panicum maximum cv Hammil and Panicum maximum cv Purpleguenea. The energy content of Panicum maximum cv Hammil was significantly lower than the two. The crude fiber of Pannicum maximum cv Hammil was significantly higher than the others, while the Ca and P content of Panicum maximum cv Purpleguenea was significantly lower than the others.
