Sweet corn is widely consumed because it has a sweeter taste than regular maize and has straw which is often used as a substitute source of fiber for livestock. Increased plant spacing was expected to increase the growth and yield of sweet corn. This research aimed to determine the effect of plant spacing on the growth and yield of sweet corn. The method used was a Randomized Complete Block Design (RCBD) with 1 treatment factor consisted of 4 levels of plant spacing, consisted of 75 × 12,5 cm, 75 × 17,5 cm, 75 × 25 cm, and 75 × 35 cm. Each level of experiment was carried out in plots measured 375 x 175 cm with a distance between plots was 25 cm. Each treatment was repeated 6 times so that 24 experimental plot units were obtained, in each experimental plot there were 3 sample plants so that 72 sample plants were obtained. Data analysis used analysis of variance at 5% level and if significant, continued using Duncan’s Multiple Range Test at 5% level. The results showed that the plant spacing of 75 × 12.5 cm gave better results of fresh weight straw per hectare and dry weight straw per hectare. The plant spacing treatment of 75 ×17,5 cm gave better results in terms of weight of cob with husk per hectare weight of cob without husk per hectare.
