Metode Penelitian dilaksanakan dalam bentuk percobaan dengan menggunakan rancangan petak terbagi (RPT), sebagai berikut : Petak Utama (PU) adalah 6 genotipe kedelai (g) mutant generasi ke 4 yaitu : g (genotipe Menyapa, 50 Gy ); g 1 2 (genotipe Orba, 50 Gy); g (genotipe Tanggamus, 50 Gy); g (genotipe Menyapa, 0 Gy); g (genotipe Orba, 0 3 4 5 Gy); g (genotipe Tanggamus, 0 Gy). Anak Petak (AP) adalah kombinasi Jenis mikoriza vesikular arbuskular 6 (m) yaitu control (tanpa mikoriza (m ), mikoriza Glomus sp. + Gigaspora sp. (m ), Glomus sp.+ Acaulospora 0 1 sp. (m ), Gigaspora sp. + Acaulospora sp. (m ), (Glomus sp. + Gigaspora sp. + Acaulospora sp.) (m ). Setiap 2 3 4 perlakuan pada petak utama, dan anak petak dikombinasikan sehingga terdapat 30 kombinasi perlakuan. Masing-masing kombinasi perlakuan diulang sebanyak 3 kali sehingga seluruhnya terdapat 90 unit tanaman. Hasil penelitian menunjukkan bahwa : kombinasi jenis mikoriza (Glomus sp. + Gigaspora sp. + Acaulospora sp.) merupakan kombinasi terbaik terhadap pertumbuhan dan produksi genotipe kedelai, Genotipe Menyapa, 50Gy; genotipe Orba, 50 Gy; genotipe Tanggamus, 50 Gy menghasilkan pertumbuhan dan produksi yang lebih tinggi dibanding genotipe Menyapa, 0 Gy; Genotipe Orba, 0 Gy; Genotipe Tanggamus, 0 Gy. Kata kunci : kombinasi, jenis, potensi, mikoriza, genotipe. ABSTRACT This study aimed to determine the potential of combination applications of vesicular arbuscular Mycorrhizae (VAM) types on the growth and production of soybean genotypes. The research was conducted in experimental forms using a Split Plot design (SPD), as follows: The main plot (MP) consisted of th six soybean genotypes (g) of the 4 mutant generations, namely Menyapa genotypes, 50 Gy (g1), Orba genotypes, 50 Gy (g2), Tanggamus genotypes, 50 Gy (g3); Menyapa genotypes, 0 Gy (g4), Orba genotypes, 0 Gy (g5), Tanggamus genotypes, 0 Gy (g6). Sub plot (SP) was a combination of Vesicular Arbuscular Mycorrhizae (m) types, namely control (without mycorrhiza (m0), Glomus sp. with Gigaspora sp. (m1), Glomus sp. with Acaulospora sp. (m2), Gigaspora sp. with Acaulospora sp. (m3), (Glomus sp. with Gigaspora sp. with Acaulospora sp.) (m4). Every treatment in the main plots and subplots was combined so that there were 30 treatment combinations. Each combination treatment was repeated 3 times, so of which there are 90 units of the plants. Results showed that the combination of types of mycorrhiza (Glomus sp. + Gigaspora sp. + Acaulospora sp.) was the best combination for the growth and production of soybean genotypes. Menyapa genotypes, 50Gy; Orba genotypes, 50 Gy; Tanggamus genotypes, 50 Gy generated higher growth and production than Menyapa genotype, 0 Gy; Orba genotype, 0 Gy; Tanggamus genotype, 0 Gy. Key words: Combination, type, potency, mycorrhizae, genotype. brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by Jurnal Online Politeknik Pertanian Negeri Pangkajene Kepulauan
