Abstract

Glasshouse experiment was conducted to study the effect of mycolThizae inoculation and it 's interaction with P supply on P leaf content and quality of oiipalm seedling. Factorial experiment was 81Tangedin Randomized Block Design with threer eplications. The first factor were mycolThizae inoculation : without inoculation, mixed mycolThizae, Acaulospora sp, Glomus manihotis, Glomus sp.l, Glomus sp.2, Glomus sp,3. The second factor were level ofRoch Phosphate fertilizer: 0 g/seedling, 2 giseedling, 4 g/seedling and 6 g/seedling. MycolThizae inoculation affected the P leaf content and percentage of infection significantly; Glomus sp decreased P leaf content. Acaulospora sp. gave the best quality of seedling, but Glomus sp.3 gave the bad one, The Rock Phosphate application did not affect on P leaf content absozptJ'on efliciency and inoculation percentage due to hIgh soil phosphoros content, 1) Dosen Jurusan Budidaya Pertanian, Faperta, WB 2) Mahasiswa Jurusan Budidaya Pertanian, Faperta, IPB '7
