Corn is the important food crop in the world. National demand for corn is increasing every year. The low productivity of corn can caused by non-intensive cultivation techniques. Efforts to increase corn production can be done by using of high yielding varieties and fertilizing. The also important factor is plant spacing. Plant spacing affects the number of plants, the process of receiving sunlight, water and nutrients which also affect the process of photosynthesis and assimilation between plants. The aim of this research was to examine the effect of different plant spacing and to evaluate plant spacing that could increase the growth and yield of hybrid corn. This research was conducted in UNS experimental field Jumantono, Karanganyar start from June-November 2019. Design utilization was exprimental method with Randomized Complete Block Design (RCBD) of 1 factor, consist of 4 levels, the treatment was 60 cm x 30 cm (J1); 60 cm x 40 cm (J2); 60 cm x 50 cm (J3); and 60 cm x 60 cm (J4). There was replicated 6 times. The result showed that plant spacing of 60 cm x 60 cm has increase on cob weight with husk, cob weight without husk, number of cob per plant and grain yield per plant compared with plant spacing of 60 cm x 30 cm. The plant spacing treatment of 60 cm x 60 cm can improve quality of yield per crop but have not been able to increase the quantity of hybrid corn yield.
