The aim of this research  was knowing the interactions that occur between Legowo row planting system and variations of fertilization on the growth and yield of rice. The research was conducted in Sentono, Karangdowo District, Klaten regency, Central Java. Research started in April to August 2016. The study uses factorial design with two factors. The first factor was the variation of fertilization that consists of three levels, namely: P1 was the dosage recommendation in the form of chemical NPK fertilizer application 600 kg / ha, P 2 = 50% chemical NPK fertilizer dosage recommendation with 10 ton / ha of BATAN’s organic fertilizer products; P3 = 50% chemical NPK fertilizer dosage recommendation with 10 ton / ha of organic compost product of the Faculty of Agriculture UPN "Veteran" Yogyakarta. The second factor was the variation of Legowo row planting system, namely: J1 = 2: 1, J2 = 3: 1, J3 = 4: 1. Each treatment was repeated 3 times and each test with 3 samples per plot, so we get 27 experimental plots in the size of 4 m x 4 m with plantation space of 12,5cm x 25 cm x 50 cm. Based on further analysis of variance with Duncan's Multiple Range Test (DMRT) with a level of 5%. The result shows that there was no interaction between Legowo row planting system and fertilizing variation on all parameters of growth and yield. Treatment of theFertilization variations P1 showed significant difference higher on all parameters growth but no significant difference lower on yield rice compared with P2 dan P3. Other hand that percent of unproductive tillers on P1 showed significant difference higher than P2 and P3. Treatment of Legowo row planting system J1 produce a significantly different higher on yield than J2 and J3, meanwhile there was no significant difference among J1 and J2 on grain weight per hill and per hectare. Organic fertilizer substituted 50% NPK and legowo row planting system 2:1 increased 12.5% to the 4:1 legowo row planting system
