Abstract: TECHAPINYAWAT, SOMBUN, University of the Philippines at Los Banos, January, 1982. Studies on Inoculation of Ipil-Ipil Leucaena leucocephala (Lam.) De Witts] with Rhizobia and Mycorrhizal Fungi. Major Professor: Dr. Percy E- Sajise. The interaction between vesicular-arbuscular (VA) mycorrhiza and Rhizobium sp. strain L-15 and varying phosphorus levels using sterile Macolod clay loam soil from Pating Lupa, Mount Makiling, Philippines and their effects on growth of Jeucaena leucocephala was studied. Mixed mycorrhizal spores obtained from rhizosphere of leucaena leucocephala was more efficient in improving growth of Leucaena compared to the other mycorrhizal types used in the inoculation treatment leucaena - Rhizobium symbiosis enhanced atmospheric nitrogen fixation, whereas mycorrhiza enhanced nutrient uptake. Double inoculation with Rhizobium and mycorrhiza increased the uptake of N, P, K, Ca, Mg, and improved growth of Leucaena greater than that of either Rhizobium or mycorrhiza treated Plants especially in soil with low phosphorus and nitrogen availability. Rhizobium and mycorrhizal inoculations stimulated nutrient uptake, nodulation, nitrogen fixation and growth of Leucaena with low phosphorus application in the soil. Phosphorus levels above 30 kg P20s/ha depressed mycorrhizal development and activities. These results showed that double symbiosis with Rhizobium and mycorrhiza were synergistic and stimulated nodulation, nitrogen fixation, nutrient uptake and improved growth of Leucaena leucocephala.

TECHAPINYAWAT, SOMBUN, University of the Philippines at Los Banos, January, 1982. Studies on Inoculation of Ipil-Ipil Leucaena leucocephala (Lam.) De Witts] with Rhizobia and Mycorrhizal Fungi. Major Professor: Dr. Percy E- Sajise.

The interaction between vesicular-arbuscular (VA) mycorrhiza and Rhizobium sp. strain L-15 and varying phosphorus levels using sterile Macolod clay loam soil from Pating Lupa, Mount Makiling, Philippines and their effects on growth of Jeucaena leucocephala was studied.

Mixed mycorrhizal spores obtained from rhizosphere of leucaena leucocephala was more efficient in improving growth of Leucaena compared to the other mycorrhizal types used in the inoculation treatment leucaena - Rhizobium symbiosis enhanced atmospheric nitrogen fixation, whereas mycorrhiza enhanced nutrient uptake.

Double inoculation with Rhizobium and mycorrhiza increased the uptake of N, P, K, Ca, Mg, and improved growth of Leucaena greater than that of either Rhizobium or mycorrhiza treated Plants especially in soil with low phosphorus and nitrogen
availability.

Rhizobium and mycorrhizal inoculations stimulated nutrient uptake, nodulation, nitrogen fixation and growth of

Leucaena with low phosphorus application in the soil. Phosphorus levels above 30 kg P20s/ha depressed mycorrhizal development and activities.

These results showed that double symbiosis with Rhizobium and mycorrhiza were synergistic and stimulated nodulation, nitrogen fixation, nutrient uptake and improved growth of Leucaena leucocephala.
