Seed was sown at the spacing of 25 and 50 cm between hills and 75 cm apart in rows. Plant per hill was set at 1, 2 and 3 plants. The results showed that when plant per hill was increased, the value measured from seven characters were also increased e.g., the plant height, ear height, number of yellow leaf per plant, percentage of lodging, number of total ear per area, number of ear with unfilled seed set per area and cob weight from the unfilled seed set per area. In contrary, the value measure2048d from other sixteen characters were decreased when increased number of plant per hill e.g., plant diameter, ear width, ear length, ear weight, 1,000 seed weight, number leaf per plant, leaf area per plant, dry weight per plant, ear number per plant, seed weight per ear, cob weight per ear, seed number per ear, seed weight per area, cob weight per area, percentage of ear with filled seed set and yield per rai. Highest seed yield of 367 kg per rai was obtained from 25 x 75 cm and 1 plant per hill (8,533 plants/rai) and 355 kg per rai was obtained from 50 x 75 cm and 2 plants per hill (8,533 plants/rai). The lowest seed yield was 210 kg per rai when sweet corn was grown at 25 x 75 cm with 3 plants per hill (25,599 plants/rai). All plant densities used in the experiment did not affect the seed qua
