Abstract
Legumes are known as green concentrate for ruminants in the tropics and their availability was essential to support livestock productivity. The research was conducted to update the morphology and nutrient quality of four species as fodder crops that grew in lowland agroecosystems (14m above sea level), namely: I. endecaphylla, I.zolingeriana, P. javanica, and P. triloba. Characterization begins with the collection of secondary and primary data, including: soil conditions (soil type, pH, macro and micro nutrients), habitus (origin, growth characteristics, and plant height), morphology (leaves, stems, flowers, fruits, seeds, cuttings/how to grow shoots), production or yield potential, quality (nutritional value and anti-nutritional content). Comparative data was presented descriptively. The results showed that the plants grow in grumosol soil with a pH of H2O 8.2, a pH of KCl 6.9 was slightly alkaline, with 0.17 percent of total nitrogen, 11.0 ppm available P2O5, and 33.08 cmol cation exchange capacity per Kg-1. The four legumes observed were local variety with the typical growth of spread, creeping and upright-branching. Except for I.zolingeriana (tap root), all three varieties have fibrous roots and compound leaves. The leaf width of P. javanica and P. triloba (22.7cm and 34.0cm) was higher than that of I. endecaphylla and I.zolingeriana (4.3cm and 11.3cm). The results of proximate analysis showed that I.zolingeriana had the highest Crude Protein content (percent) (22.0), followed by P. triloba (18.6), P. javanica (18.2), and I. endecaphylla (15.5). While the highest Neutral Detergent Fiber content (percent) was found in P.triloba (59.5), followed by I.zolingeriana (57.4), P. Javanica (57.4), and I. endecaphylla (49.9). The four legumes had secondary metabolites. P. javanica showed the highest concentration of total Alkaloids, Saponins, Terpenoids, Tannins, Phenolics, and total Flavonoids which ranging from 73.5 to 3685.5 ppm. However, the four legumes were safely
