A research was intends to determine the effect of straw embedding and earthworm adduction on the growth and yield of rice crops. This research was conducted in April until August, 2017 at Greenhouse, Faculty of Agriculture, Universitas Muhammadiyah Yogyakarta. This research was conducted by using experimental method in a plastic wooden tub. This research was prepared in Complete Randomized Design (CRD) using a single factor treatment design. This research consisted of 3 treatments with 4 replications, so there were 12 experimental units. The treatments are P1 (without the adduction of straw and earthworms), P2 (embedding of 5 tons/hectare of straw), and P3 (embedding of 5 tons/hectare of straw + 60 earthworms/10 kg of soil). The results indicated that the straw embedding and earthworm adduction gave significant effect on the number of tillers, fresh crown weight, dry grain weight, grain yield/hectare on rice plants.
