The aim of this research was to test the growth of palm oil varieties seedlings with some concentration of nutrients. This research was conducted at Greenhouse Faculty of Agriculture University of Sumatera Utara, from August to October 2017. The research design used randomized block design (RBD) with 2 factors. The first factor was varieties consist of 3 varieties namely DxP Avros, DxP Langkat, and DxP Yangambi. The second factor is the concentration consisting of 4 levels (8 HS, 1 HS, 1,2 HS and 1,4 HS). The observed variables were plant height (6, 8, 10, and 12 weeks after planting), number of leaves, stem diameter, root number and root length. The results showed that varieties significantly different to the plant height, stem diameter, and root length. The different concentration of nutrients had no significantly effect to all observed variables, and there was no interaction between the two treatments. 6 observed variables had high heritability at plant height 6, 10, and 12 weeks after planting, number of leaves 8 weeks after planting, stem diameter, and root length characters.
Penelitian ini bertujuan untuk menguji pertumbuhan beberapa varietas bibit kelapa sawit dengan pemberian beberapa konsentrasi nutrisi AB Mix dengan sistem hidroponik di pre nursery. Penelitian ini dilaksanakan di Rumah Kaca Fakultas Pertanian USU dari bulan Agustus sampai dengan Oktober 2017. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) dengan 2 faktor perlakuan. Faktor pertama adalah varietas yang terdiri dari 3 varietas yaitu DxP Avros, DxP Langkat, dan DxP Yangambi. Faktor kedua adalah konsentrasi yang terdiri dari 4 taraf yaitu 8 HS, 1 HS, 1,2 HS dan 1,4 HS. Peubah amtan yang diamati adalah tinggi tanaman, jumlah daun, diameter batang, jumlah akar dan panjang akar. Hasil penelitian menunjukkan bahwa perlakuan varietas berbeda nyata terhadap peubah amatan tinggi tanaman pada umur 6, 8, 10, dan 12 MST (minggu setelah tanam), diameter batang, dan panjang akar. Sedangkan pemberian konsentrasi nutrisi yang berbeda berpengaruh tidak nyata terhadap semua peubah amatan yang diamati, serta tidak ada interaksi antara kedua perlakuan. Terdapat 6 peubah amatan yang memiliki nilai duga heritabilitas tinggi, yaitu tinggi tanaman 6, 10, dan 12 MST, jumlah daun 8 MST, diameter batang, dan panjang akar pada karakter.
