Pemberian Pupuk Hayati Konsorsium Bakteri Selulolitik Berbasis Limbah Cair Organik Terhadap Pertumbuhan Dan Hasil Tanaman Kedelai (Glycine Max (L.) Merrill) Pada Tanah Ultisol
ABSTRACT
Soybean is a concern of the Ministry of Agriculture because of the increasing demand along with the increase in the domestic population while soybean production is decreasing. Efforts that can be made to increase soybean production are by developing the area of cultivated land. Meanwhile, fertile agricultural land is increasingly limited so that its expansion can only be carried out on marginal lands such as Ultisol soil which has several problems. Therefore, fertilization and organic matter are expected to improve Ultisol soil fertility. The fertilization technology used is biological fertilizer. Microorganisms used in the manufacture of biofertilizers in this study were cellulolytic bacteria consisting of six isolates from oil palm empty fruit bunches, acacia litter and rice straw that had been consorted. While the nutrient providers for bacteria to survive include rice washing water, tofu liquid waste, coconut water waste and oil palm liquid waste. This research was conducted experimentally using a non-factorial completely randomized design which consisted of 12 treatments. The results showed that the biofertilizer of a consortium of cellulolytic bacteria based on organic liquid waste affected the growth of soybean plants where a dose of 15 ml of biofertilizer of liquid waste from rice washing water and tofu water obtained the highest plant yield and the highest number of productive branches. Biofertilizer of oil palm liquid waste at a dose of 15 ml obtained the highest total number of root nodules and the highest number and percentage of effective root nodules among other treatments.
