Penelitian ini bertujuan untuk mengetahui pengaruh beberapa dosis mikoriza Glomus mosseae dan galur mutan terhadap pertumbuhan vegetatif dan generatif kedelai serta mengetahui interaksi antara kedua faktor tersebut. Penelitian ini dilaksanakan di Kebun Percobaan Dua Sektor Timur, Pengamatan persentase akar terkolonisasi mikoriza dilakukan di Laboratorium Hortikultura Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh. Analisis data yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok pola Faktorial 3 x 4 dengan 3 ulangan, sehingga terdapat 12 kombinasi perlakuan dan 36 unit percobaan, setiap perlakuan terdiri atas 4 tanaman. Faktor pertama adalah dosis mikoriza terdiri atas 3 taraf, yaitu : M0 = 0 g pertanaman, M1 = 10 g pertanaman, M2 = 20 g pertanaman. Faktor kedua adalah galur mutan kedelai Kipas Putih terdiri atas 4 taraf, yaitu : G0=Tetua, G1=B4, G2= B7, G3=B18. Parameter yang diamati yaitu tinggi tanaman, jumlah cabang produktif, umur berbunga, umur panen, jumlah polong total pertanaman, jumlah polong bernas pertanaman, persentase polong bernas pertanaman, persentase akar terkolonisasi mikoriza. Hasil analisis sidik ragam menunjukkan bahwa dosis mikoriza berpengaruh sangat nyata terhadap tinggi tanaman umur 4 MST, jumlah cabang produktif, jumlah polong total pertanaman dan persentase akar terkolonisasi mikoriza. Berpengaruh tidak nyata terhadap tinggi tanaman umur 2, 6, 8 dan 10 MST, umur berbunga, umur panen, jumlah polong bernas pertanaman dan persentase polong bernas pertanaman. Perlakuan galur mutan kedelai berpengaruh sangat nyata terhadap jumlah cabang produktif dan umur berbunga serta berpengaruh tidak nyata terhadap tinggi tanaman umur 2, 4, 6, 8, dan 10 MST, persentase polong bernas pertanaman dan persentase akar terkolonisasi. Tidak terdapat interaksi antara dosis mikoriza Glomus mosseae terhadap pertumbuhan vegetatif dan generatif beberapa galur mutan kedelai pada peubah yang diamati

This research aims to determine the effect of several doses of Glomus mosseae mycorrhiza and mutant strains on vegetative and generative growth of soybeans and to determine the interaction between these two factors. This research was carried out at the Two East Sector Experimental Gardens. Observations on the percentage of mycorrhizal colonized roots were carried out at the Horticulture Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. The data analysis used in this research was a 3 x 4 Factorial Randomized Block Design with 3 replications, so there were 12 treatment combinations and 36 experimental units, each treatment consisting of 4 plants. The first factor is the mycorrhizal dose consisting of 3 levels, namely: M0 = 0 g per plant, M1 = 10 g per plant, M2 = 20 g per plant. The second factor is the White Kipas soybean mutant line consisting of 4 levels, namely: G0=Elder, G1=B4, G2=B7, G3=B18. The parameters observed were plant height, number of productive branches, flowering age, harvest age, total number of pods per plant, number of fruity pods per plant, percentage of fruity pods per plant, percentage of mycorrhizal colonized roots. The results of analysis of variance showed that mycorrhizal dosage had a very significant effect on plant height at 4 WAP, number of productive branches, total number of pods per plant and percentage of mycorrhizal colonized roots. There was no significant effect on plant height aged 2, 6, 8 and 10 WAP, flowering age, harvest age, number of fruity pods per plant and percentage of fruity pods per plant. The treatment of soybean mutant lines had a very significant effect on the number of productive branches and flowering age and had no significant effect on plant height aged 2, 4, 6, 8 and 10 WAP, the percentage of pithy pods planted and the percentage of colonized roots. There was no interaction between the dose of Glomus mosseae mycorrhiza on the vegetative and generative growth of several soybean mutant lines on the variables observed.
