Abstract

Kurniaty R. 2016. The use of mycorrhiza and Rhizobium in the growth of three months saga seedling (Adenanthera pavonina). Pros Sem Nas Masy Biodiv Indon 2: 6-9. Plants saga tree (Adenanthera pavonina) having benefits versatile because almost all parts of the crop can be used so that economically valuable high. Wood saga can be used as building material and furniture. Seeds saga have the potential who has a promising as a renewable energy source of them because of the seeds his containing 14-28% fatty oil which could be classified as non-food. In addition, oil derived from the seeds of the saga is also very good to treat a disease in, scurvy, injuries, making candles, batik industry, and materials making soap. The research aims to understand the influence of the use of mycorrhizal and Rhizobium in growth seedlings saga age 3 months. Inoculating Rhizobium liquid as many as 1 mL using injecting on roots and plants surrounding the hole. The provision of mycorrhizal done by entering 2 g mycorrhizal (Glomus sp.) into a whole plant at the same time as Rhizobium. The design used is a random factorial consisting of two factors treatment. The first is Rhizobium (A) namely: A1 = control and A2= Rhizobium sp. The second factor is mycorrhizal (B) consisting of two the standard: B1 = control and B2 = Glomus sp (2 g/ polybag). The results showed that the treatment A2B2 (Rhizobium + mycorrhizal) put a value colonization roots highest namely 68.88% with live percent 99.26%, height 10.08 cm, diameter 1.67 mm, biomass 0.56 g, TR ratio 2.01 and IMB 0.06. Nutrient absorption, treatment A2B2 is the nutrient in N 60.30% compared to control, the nutrient P 66.66% compared to control and the nutrient K 123.17% compared to control.
