Effect of Phosphate Solubilization Microorganism (PSM) and Plant Growth Promoting Rhizobacteria (PGPR) on Yiels and Yield Component of Soybeans (Glycinemax)

In order to study the effect of Rhizobium, vesicular Arbuscular Mycorrhiza (VAM) and plant growth promoting rhizobacteria (PGPR) on soil enzymatic activities, yield and yield components of soybean (Glycine max L.) an experiment was conducted at Malinau-East Kaliamantan during dry season 2010. Experiment laid out as split plot based on randomized complete block design with five replications. Application of Rhizobium and check or without Rhizobium) were as main plots and four biofertilizers (Vesicular Arburcular Mycorrhiza (T1); Pseudomonas sp., Bacillus sp. and Streptomyces sp (T2); combination of T1 &T2 and and check or without any biofertilizer were as sub plots treatments. Results showed that treatments of biofertilizer (Rhizobium and VAM), liquid organic biofertilizer and both combination increased ratio of filled pod to empty one and soil enzymatic activities and subsequently reduce the intensity of leaf spot diseases. The correlation of biofertilizer with soil biochemical properties will be discussed more detail in this paper. Proseding Seminar Nasional Pengelolaan Organisme Pengganggu Tanaman Ramah Lingkungan.
