Abstract

The objective of this research was to determine the best biourine concentration on the rubber seedling. This research was conducted at Teaching and Research Farm, Agriculture Faculty, Mendalo Darat, Jambi. This experiment was designed using completely Randomized Design with five treatment, and three replications. The treatments were  the level of biourine concentration : uo= 0% bio-urine, u1= 2,5%, u2= 5,0%, u3= 7,5% dan u4= 10,0%. Three were 15 units of treatments. Statical analysis showed that cattle biourine  at  7, 5 % gave the best growth of rubber seedling, shoot height and root dry weight. Key word: Urine , rubber, shoot

Abstract

The research investigated the influence of four isolates of arbuscular mycorrhizal fungi(AMF) on the growth of duku seedlings. The research used randomized block design with onefactor of some isolates AMF: Glomus-sp 3, 6, 15, and 16 at a dose of 20 g per polybag. The resultsshowed that inoculation of AMF isolates increase the canopy and root growth of the dukuseedlings. Duku seedlings inoculated with mycorrhiza showed higher plant height, stem diameter,dry weight, secondary roots number and length, than the control. Furthermore, mycorrhizalinoculation increased the absorption of nutrients (Phosphor) in the leaves of duku seedlings. Rootstaining results showed that AMF colonization in the duku roots only indicate hyphae; the otherstructures (vesicles, arbuscular and spores) were not detected.
