Abstract

Penelitian ini bertujuan untuk mengetahui keragaan fenotipe progeni kedelai generasi F4 yang dapat tumbuh dan berproduksi tinggi pada tanah salin berdasarkan karakter agronomis. Penelitian ini dilaksanakan di rumah plastik lahan Fakultas Pertanian, Universitas Sumatera Utara, Medan dengan ketinggian tempat ±25 meter di atas permukaan laut pada bulan Februari sampai Juni 2016. Analisis yang digunakan dalam penelitian ini adalah analisis sidik lintas dan uji t pada generasi F4. Parameter yang diamati adalah tinggi tanaman, jumlah cabang, luas daun atas, luas daun tengah, luas daun bawah, umur berbunga, umur panen, jumlah polong, jumlah polong berisi, jumlah polong hampa, bobot biji per tanaman, bobot 100 biji, dan bobot per biji. Hasil menunjukkan bahwa komponen yang memberi pengaruh langsung positif terbesar terhadap produksi biji per tanaman pada kondisi salin adalah  jumlah polong dan komponen yang memberikan pengaruh tidak langsung terbesar adalah umur panen. Tanaman yang terpilih berdasarkan produksi bobot per biji tanaman dengan intensitas seleksi 20% terdapat pada 5 nomor tanaman yaitu P2.16.7; P3.28.1; P3.54.6; P3.69.2; dan P6.6.3.

Abstract

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.
