"Current recommendations for fresh market sweet corn suggest row spacing of 30 to 40 inches and in-row spacing of 8 to 10 inches for early varieties and 9 to 12 inches for late varieties. This corresponds to populations from 13,068 to 26,136 plants per acre. Variety trials at Pinney-Purdue Agricultural Center have been planted at row spacings of 30 or 36 inches and populations of 20,328 plants per acre. Some cultivars may perform well at higher populations. This trial was conducted to evaluate yield and ear characteristics of two cultivars at populations up to 50% higher than normally used in Purdue variety trials."
