Abstract

Tembesu (Fagraea fragrans Roxb.) Is one tree that is very popular in Southern Sumatra region as raw material for carving and furniture industry. The need for wood reaches 3 120 m³ per year and has been supplied from plants that grow naturally or from community forest. The purpose of this study was to determine the production potential of fruit each branch so that it can predict preparations to facilitate the expansion of planting seedlings. Tembesu trees including types with wide adaptability to a place to grow as on dry land, waterlogged soil or land tides. This type includes the category of intermediate cycle (10-30) years. The average production of fruit each branch of Ogan Ilir 38 094.53 fruits, 1000 grain weight of 0.3066 gr and initial KA 7.2% textured clay dusty land. Production of Ogan Komering Ilir with sandy soil texture reach 88 862.27 fruits, 1000 grain weight of 0.2548 gr and initial seed KA 7.7%. The average production of fruit each branch is influenced by soil texture is sandy land (OKI, swamp / stagnant) production higher than that of land dusty clay (OI, dry / stagnant).Key words : tembesu, fruit production, wide adaptability

Abstract

Salah satu hal terpenting dalam penyediaan bibit tanaman adalah media yang digunakan dalam pembibitan.  Tujuan dari penelitian ini adalah untuk mengetahui pengaruh media kompos yang diberikan dan asal benih kranji (Pongamia pinnata) terhadap pertumbuhan tinggi bibit di persemaian.  Penelitian dilakukan dengan menggunakan benih yang berasal dari Bangka, Carita, Batukaras dan banyuwangi.  Masing-masing bibit hasil perkecambahan dilakukan penyapihan dalam polybag dan dilakukan pengukuran sebanyak 3 kali.  Berdasarkan hasil penelitian dapat disimpulkan bahwa pada α = 5% pertumbuhan bibit tanaman kranji sangat dipengaruhi oleh penggunaan jenis kompos dan tidak dipengaruhi oleh lokasi asal benih. Pembibitan tanaman kranji lebih membutuhkan pupuk kompos sebagai pemberi nutrisi dan perbaikan struktur media.  Media is an important in the making seedling and it use in the production of cultivated seeds have economic value, is easily available and the range of non-destructive.  Determination of nutrients in the medium nursery is one of the factors to produce seedlings with a good quality.   The aim of research is produce of good seedling based on the compost type (conventional and brand) and origin of seed (Bangka, Carita and Banyuwangi). The result is  α = 5% come from type of compost (conventional) of randomized block design with 4 treatments. Compost, besides as fertilizer also contribute improving the structure of media for producing kranji (Pongamia pinnata) seedlings.
