【 摘 要 】

The effort to secure the sustainability of rice productivity is one of the main priority in providing enough food for rapidly growing population in Indonesia. Meanwhile, intensive use of agrochemicals fertilizers since the adoption of green revolution not only has boosted food production significantly but also accelerated to the soil health degradation. The intensive research has been done to develop of biofertilizers as consortia of inoculants (Azotobacter sp., Azospirillum sp., Pseudomonas sp., Bacillus sp., and Acinetobacter sp). The formulated bioterilizers combined with water saving technology were implemented' as an integrated organic-biofertilizers based of nutrients management and 'water saving technology, known as "IPATBO". Two young single rice seedling were planted at 30x35 cm, fertilized with 2-5 ton ha-1 of organic ameliorant, and' 500-1000 g of biofertlizers inoculant. The summarized field results from 2007-2018 at different locations in revealed that (1) the efficiency of water irrigation uses was increased by 35 %, (2) twin seedling planting technique of IPATBO increased the rice grain yield by 20-30 % compare to conventional methods, (3) application of 2-5 tons ha-1 of organic ameliorant reduced the application inorganic fertilizers by 25-50 %, improved the soils health and increased the rice productivity significantly. The obtained rice grain yield ranged from 6-11 t ha-1 was increased by 50-200 %. Briefly, IPATBO has a great prospect to increase the productivity from 5-6 to 6-8 tons ha-1 of rice grain yield and to improve the sustainability of food security in Indonesia.
