    Abstraksi

    Molibdenum (Mo) merupakan unsur yang penting untuk pembentukan nodul dan metabolisme nitrogen oleh tumbuhan legum. Sehingga penelitian ini dilakukan untuk menguji efek Molibdenum pada pertumbuhan dan hasil tanaman kedelai (Glycine max L. Merr.). Bahan penelitian yang digunakan adalah kedelai varietas GEMA, jenis tanah mediteran merah, pot plastik, (NH 4 ) 6 Mo . Penelitian dilaksanakan di Rumah Plastik di Kebun Percobaan Agroteknologi Universitas Trunojoyo Madura dengan ketinggian tempat ±5 meter diatas permukaan laut, sejak bulan Desember 2017 – Maret 2018. Rancangan lingkungan menggunakan Rancangan Acak Lengkap (RAL). Rancangan perlakuan satu faktor dengan takaran 150 g/ha – 600 g/ha. Pengamatan dilakukan secara destruktif terhadap parameter pertumbuhan dan hasil. Data dianalisis dengan Anova dilanjutkan BNJD taraf 5%. Hasil analisis pengaruh Molibdenum berpengaruh nyata terhadap jumlah bintil akar tetapi tidak berbeda nyata pada variabel jumlah akar, bobot kering akar, tinggi tanaman, jumlah cabang, jumlah polong isi setiap tanaman, dan bobot biji kering serta biomassa tanaman (akar, batang dan daun). Kata kunci: Kedelai, Molibdenum, Pertumbuhan dan Hasil.

    Abstraction

    Molybdenum (Mo) is an important element for nodule formation and nitrogen metabolisms by legume plant. The research to examine effects of Mo on growth and production of Soy plant. The materials used are soybean varieties of GEMA, Mediteran soil, plastic pot and (NH 4 ) 6 Mo 7 O . The research was carried out in the experimental farm Agrotechnology of Trunojoyo Madura University with approximately 5 meters above sea level.The research was arranged in complete random design (CRD) with treatments consisted of two levels namely 150 and 600 g (NH4) 6 Mo 7 O 24 24 /ha. Data were analysed by Anova and the difference among means were analysed by DMRT ? 5%. The result showed that Mo significantly increased number of root nodules but not on root number, root dry weight, plant height, branch number, total number of pod per plant, weight of dry seed, and dry matter of plant biomass. Possibly, other factors from soil that may interact the effect of Mo on growth and yield of soybean were discussed. Keywords: Soybean, Molybdenum, Growth and Results.
