Abstract. The experiment aims to knowing the effect off row circle planting method on growth of sweet corn. This research was conducted in the Sub District of Siman District of Siman, Ponorogo, with altitude 140 amsl and textured clay grumosol soil types. The research used a randomized block design (CBD) with 4 kinds of planting spaces included C1 = 8 plant / (60x80) cm2, C2 = 16 plant / (60x80) cm2, C3 = 12 plant/ (60 x 80) cm2, C4 = 1 plant/ (60 x 80) cm2, C5 = 1 plant/ (60 x 80) cm2 with mowing. Each experimental unit was repeated 5 times so that there were 25 units. The observation was done at on 21,28, 35, 42 and DAP (day after planting). Some vegetative growth traits of sweet corn were determined as: plant height (cm), no. of leaves (leaf plant-1), leaf area (m2). Data obtained from observations were analyzed using analysis of variance (ANOVA) with a confidence level of 95%. The result showed not significantly different between row circle planting method on height of plant, number of leaf, leaf area, and leaf area index. However, it was clearly seen on the graphic that in treatment with C1 = 8 plant / (60x80) cm2 on 49 dap had the tallest height with a value of 194.60 cm. On the other hand, was observed in treatment 1 plant/ (60 x 80) cm2 with a value of 184.40 cm.
