INTISARI Penelitian ini berjudul Pengaruh Perendaman Air pada Benih Nangka (Artocarpus heterophyllus Lamk.) dengan Berbagai Posisi Tanam Benih terhadap pertumbuhan bibit. Penelitan ini bertujuan untuk mengetahui pengaruh perendaman benih nangka dalam air dan benih ditanam dengan berbagai posisi tanam terhadap pertumbuhan bibit nangka. Penelitian ini dilakukan di Laboratorium Hortikultura dan Rumah Kawat, Jurusan Budidaya Pertanian, Fakultas Pertanian, Universitas Gadjah Mada, Yogyakarta pada bulan Februari sampai dengan Juli 2016. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial 2 x 5 dengan ulangan tiga kali. Faktor pertama adalah benih nangka ditanam dengan berbagai posisi, terdiri atas 2 level yaitu T1 (tengkurap) dan T2 (terlentang). Faktor kedua adalah perendaman benih nangka dalam air terdiri atas 5 level yaitu P1 (direndam satu hari), P2 (direndam dua hari), P3 (tanpa perlakuan/kontrol), P4 (tanpa direndam satu hari) dan P5 (tanpa direndam dua hari). Pengamatan dilakukan terhadap gaya berkecambah, indeks vigor dan indeks vigor hipotetik. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara faktor perendaman terhadap posisi tanam benih terhadap pertumbuhan bibit. Benih nangka yang ditanam tengkurap memberikan kualitas pertumbuhan terbaik. Benih nangka yang direndam selama satu hari memberikan pengaruh terbaik terhadap pertumbuhan bibit.

ABSTRACT Research titled Influence of Water Immersion on Seeds Jackfruit (Artocarpus heterophyllus Lamk.) by Various Positions Planting Seeds on seedling growth. This research was conducted to determine the effect of soaking seeds of jackfruit (Artocarpus heterophyllus Lamk.) at various positions on the growth of jackfruit seedlings. Research conducted at the Laboratory of Horticulture and WireHouse, Department of Agriculture, Faculty of Agriculture Gadjah Mada University Yogyakarta in February to July 2016. The objective of the research to determine the effect of soaking seed of jackfruit at various positions on the growth of seedlings of jackfruit. Research used a completely randomized design (CRD) factorial 2 x 5 with three replications. The first factor is the treatment of water immersion and without soaking consisting of P1 (soaked one day), P2 (soaked two days), P3 (without treatment / control), P4 (without soaked one day) and P5 (without soaked two days). The second factor is the position of seeding (hilum) that consists of T1 (stomach) and T2 (supine). Observations were made to force germination, vigor index and vigor index hypothetical. The results showed that there is no interaction between the immersion factor of the position of planting seed to growth. Jackfruit seeds were planted by the prone position gave the best growth quality. Jackfruit seed was soaked for one day gave the best effect on the growth of seedling.
