Purpose of this study is to get balanced fertilization technology to reduce the use of inorganic fertilizer> 20% and K fertilizer efficiency of = 50% to increase rice productivity in Buru held in the village of the District Waelo Waeapo, Buru, January-December 2011. Treatments tested consisted of the first factor is the kind of organic fertilizer (O), ie without organic matter (O0); straw compost added 3 t / ha (O), and manure added 3 t / ha (O21) and the second factor is 5 doses of inorganic fertilizer (A), ie 0% x dose of NPK Phonska (A), 25% x dose of NPK Phonska (A1), 50% x dose of NPK Phonska (A2 ), 75% x Phonska dose of NPK (A) and 100% NPK dose x Phonska (A). Straw compost used at this stage of the study was obtained from the results of the straw while composting manure compost taken from the composting is done by local farmers. Each treatment was repeated 3 times, the total treatment is 45 treatments. Base used urea fertilizer 150 kg / ha. Lowland rice varieties are grown in a manner Cigeulis transplanting and planting system tiles are applied with a spacing of 25 cm x 25 cm. Pest control is done in an integrated manner. Parameters measured were maximum vegetative phase of plant height, number of tillers per hill, number of productive tillers per hill and panicle length, number of grains per panicle, number of empty grains per panicle, number of filled grains per panicle, weight 1000 grain seeds, tile result, the yield per hectare). The results of the study showed that 1) the use of manure and rice straw compost at a dose of 3 tons per hectare to increase productivity in succession of paddy rice 4.37 tons / ha and 4.51 t / ha, 2) Provision of straw compost at a dose of 3 tons per ha was able to save the use of chemical fertilizers by 50%. 430
