Abstract


Biofertilizer mengandung mikroorganisme hidup dengan kemampuan melarutkan unsur makronutrien dan memproduksi fitohormon. Konsorsium bakteri merupakan kumpulan dari 2 atau lebih bakteri yang membentuk suatu komunitas dari genus yang berbeda. Agar mendukung aplikasi biofertilizer diperlukan adanya sinergisme antar bakteri. Pada penelitian ini akan dilakukan uji sinergisme dan uji potensi biofertilizer secara kualitatif. Tujuan dari penelitian ini adalah mengetahui sinergisme dan potensi bakteri sebagai biofertilizer. Hasil menunjukkan bahwa dengan deteksi kualitatif  keenam isolat bakteri tersebut tidak mampu menambat nitrogen, melarutkan fosfat dan kalium serta tidak dapat memproduksi fitohormon IAA namun dapat bersinergi secara positif.

Keywords


biofertilizer; fosfat; kalium; IAA; nitrogen; sinergisme.
