In order to fulfil rice production, there were new land clearing programs outside Java, including Merauke, Papua. There were several obstacles on rice cultivation in this area such as low soil fertility which has an effect on less optimal production. The objective of the research was to determine the effect of rice straw with biodecomposer and biofertilizer application for improving soil quality in new land clearing in Merauke, Papua. The research design was a split plot with the main factor was fertilizer (with and without rice straw with biodecomposer and biofertilizer application). The sub factor was three kinds rice varieties. The data were collected consist of soil chemical and biological properties, the rice growth and yield components. The results showed the addition of fertilizer did not significantly improved soil quality in new land clearing in Merauke, Papua. On the contrary, biofertilizer affect to seed vigor and viability in the nursery. The fertilizer addition significantly effected on rice growth and yield components, it was suspected by rice varieties having different resistance to pests and diseases and straw as compost will suppress the blast growth through temperature factor during decomposition. The highest yield was reached by Inpari 33 of 8.20 Mg ha −1 .
