Double cropping is important for increase of farm income and rate of arable land utilization. This study was carried out to obtain information for optimum plant density of the second crop in a double cropping system. A waxy corn hybrid, Chalok 2, was sown on July 10 at the first corn cropping site. Growth characteristics and yield response of fresh waxy corn were examined under different planting densities, which were 55.5, 66.6, 83.3, and 111.1 thousands plants ha deci. Plant height was higher under high planting density than low planting density and 154 cm at the 55.5 thousand plants ha deci, and 168 cm at the 111.1 thousand plant ha deci.
