The combination use of biofertilizer and inorganic nitrogen (N) fertilizer is required to increase rice productivity and reduce land degradation. This study aims to determine the responses of four rice varieties in various fertilization packages that can save inorganic N by using nitrogen fixing bacteria as bio–fertilizer. The research was conducted in the Experimental Farm Faculty of Agriculture, Hasanuddin University. A randomized block design (RBD) with two–factors between varieties and fertilizer package was selected. The results revealed that Pandan Putri variety had the best result based on the 1,000 grains (28.42 g) weight while Inpari Sidenuk variety was excellent based on per clump weight of rice grain of 71.64 g. Ciliwung variety showed the best quantity of productive tiller (16.44 tiller). The fertilization package of half–dose urea in combination with 2.5L of Azotobacter demonstrated the best number of productive tillers (17.03 tiller) and grain weight (73.10 g) with a two times (1.25–0–1.25) application. It was concluded that the combination of half dose urea and biofertilizer of Azotobacter increased the growth and production of rice plant.
