Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Abstrak Inokulasi Fungi Mikoriza Arbuskular (FMA) pada fase pembibitan kelapa sawit dapat meningkatkan kualitas bibit. Adanya FMA pada akar bibit kelapa sawit membantu pengoptimalan masa pertumbuhan awal bibit di pembibitan ataupun di lapangan. Namun, dewasa ini dosis dan waktu inokulasi FMA pada bibit kelapa sawit belum diketahui secara pasti. Oleh karena itu, penelitian ini bertujuan untuk 1) mengetahui waktu inokulasi FMA yang tepat, 2) mengetahui dosis FMA yang tepat, 3) mengetahui hubungan antara waktu inokulasi dan dosis FMA terhadap pertumbuhan bibit kelapa sawit. Penelitian dilaksanakan pada bulan Oktober 2011 sampai dengan Juni 2012 di Laboratorium Produksi Perkebunan dan rumah plastik Fakultas Pertanian Universitas Lampung. Penelitian menggunakan 2 faktor perlakukan yaitu 4 taraf dosis FMA ( 0, 200, 400, dan 600 spora) dan 4 taraf waktu inokulasi ( 0, 1, 2, dan 3 bulan setelah bibit di semai). Inokulum spora FMA yang digunakan adalah campuran dari Glomus sp.1, Glomus sp.2, Glomus sp.3, Entrosphospora sp, dan Gigaspora sp. Perlakukan diterapkan ke dalam satuan percobaan menurut Rancangan Kelompok Teracak Sempurna (RKTS). Kesamaan ragam antar perlakuan diuji dengan Uji Bartlett, sedangkan kemenambahan data diuji dengan uji Tukey. Pemisahan nilai tengah diuji dengan uji Beda Nyata Terkecil (BNT) pada tarafα 0,05. Hasil penelitian menunjukkan bahwa waktu inokulasi saat bibit berumur 1 bulan meningkatkan pertumbuhan bibit kelapa sawit melalui peningkatan bobot kering tajuk, bobot segar tajuk, dan tinggi tanaman, sedangkan dosis 400 spora FMA meningkatkan pertumbuhan bibit kelapa sawit melalui peningkatan bobot kering tajuk, bobot kering akar, bobot segar tajuk, jumlah daun, tinggi tanaman, dan persen infeksi akar. Respons bibit kelapa sawit terhadap waktu inokulasi ditentukan oleh dosis inokulum spora FMA yang digunakan hanya pada variabel pengamatan tingkat kehijauan daun dan tinggi tanaman, tidak nyata pada variabel kunci (bobot kering akar dan tajuk) sehingga dosis inokulum spora FMA yang tepat untuk masing-masing waktu inokulasi tidak dapat diketahui. Kata kunci : waktu inokulasi, dosis inokulum spora fungi mikoriza arbuskular, bibit kelapa sawit. Abstract Inoculation of arbuscular mycorrhizal fungi (AMF) at seedling stage of oil palm will improve the quality of the seedlings. The presence of AMF inside oil palm seedlings root will enhance the seedlings growth at nursery stage and later in the field. However, the information on the right time to inoculation the germinated seed of oil palm and how much the spore number of AMF to be used are limited. The presence study therefore aimed 1) to determine the exact time of AMF inoculation, 2) to determine the exact dose of AMF spore, 3) to determine whether the exact dose of AMF spore to be used is depend on the inoculation time, and 4) to determine the exact dose of AMF spore for every inoculation time. This experiment was conducted from October 2011 to June 2012 at plastic house and Laboratory of Estate Crop, Faculty of Agriculture, University of Lampung. A two factors experiment arranged in a randomized block design was used. The first factor was four level of inoculation time (0, 1, 2, and 3 months old the seedlings) and the second factor was four level of AMF spore number (0, 200, 400, and 600 spores). The AMF Inoculum used comprising Glomus sp.1, Glomus sp.2, Glomus sp.3, Entrosphospora sp, and Gigaspora sp. The data optained were subjected to Barlett test to evaluate the homogeneity of variances among the treatments and Tukey test to check the additivity of the data. The least significant difference (LSD) test in α level 0,05 was used for mean separation. The results obtained showed that AMF inoculation at one month old seedlings had the better growth of the seedlings through the increment of seedlings height, shoot fresh weight, and shoot dry weight, while 400 spore number gave the better seedling growth through the increment of seedling height, number of leaves, shoot dry weight, root dry weight, and percentage of root infection. Number of spore to be used was determined by the time of inoculation only detected at plant height and leaf greenness level. Therefore, the best combination of spore number and time of inoculation could not be determined in this study. Key words : time of inoculation, spore number of arbuscular mycorrhizal fungi, oil palm seedling.
