To solve the problem of carrier based biofertilizer, which had short comings of less microbial viability resulting in poor response in field, Bio NPK-Liquid biofertilizer (Plant Growth Promoting Bacterial-PGPB consortium) technology was developed at AAU and brief details of technology are given below. Unique traits of ‘Bio NPK-Liquid biofertilizer (PGPB consortium)’. • Bio NPK-Liquid biofertilizer (PGPB consortium) is a consortium of nitrogen fixing (Azotobacter chroococcum ABA 1, Azospirillum lipoferum ASA 1), Phosphate solubilizing and Potash mobilizing native bacteria (Bacillus 3 sp.), which are all compatible with each other. • Shelf life more than 1 year • Microbial population of 50 crores per ml • Better efficiency • Save Nitrogen, Phosphorus & Potash to the tune of 25-30 % • Increase crop production up to 8-10 % • Eco-friendly and non-polluting • Easy to use and transport • Acceptable by farmers • Suitable for drip irrigation and greenhouse • Highly advantageous for organic farming. • Useful in all crops however, when it is to be used in pulses, application of Rhizobium culture with Bio NPK is desirable.
