ABSTRACT: Intensive use of fertilizer N will stimulate mineralization of soil organic matter, causing a decrease in organic C content dan decreased soil health. Remediation of health and fertility of paddy fields can be done by utilizing the integrated biofertilizer with straw compost. This study aims to get a diluent of biofertilizer and available around the farmers as well as to test the ability of biofertilizers in increasing rice yields with two cropping systems (IPAT and Legowo). IPAT application of cropping systems on biofertilizer application with three a diluent (husk, compost and manure) gives the average number of panicles per hill and higher grain yield, respectively for 23,23% and 11,3% compared to treatment legowo cropping systems. Diluents rational biofertilizer is manure and compost, good for cropping systems and Legowo IPAT. The highest grain yield occurred at doses of urea fertilizer application of 200 kg ha-1, 2 ton ha-1 straw compost and 400 g ha-1 biofertilizer, planting system IPAT with compost as a diluent of biofertilizer that is equivalent to 8,85 tons ha-1.
