Abstract
`Silver Queen', `Incredible', and `Challenger' sweet corn ( Zea mays L.) cultivars were evaluated at different nitrogen (N) fertilization rates at Springfield, Tenn., in 1993, 1994, and 1995. `Incredible' was more productive than `Silver Queen' and `Challenger'. Of the three cultivars, `Silver Queen' had the tallest plants, longest ears, and most attractive ears. Nitrogen fertilization rates were 0, 50, 100, and 150 (100 lb/acre at planting and 50 lb/acre sidedressed) lb/acre (0,56, 112, and 168 kg·ha -1 ). The 100 lb/acre rate of N applied at planting appeared to be sufficient for producing sweet corn in soils with an annual cropping frequency. Height of plants and ear diameters were larger at the higher fertilization rates, but differences among treatments were not great and were usually not significant. The cultivars of different genetic types did not differ in response to N fertilization rates. Cultivar × year interactions were significant for most factors evaluated, but most other interactions were not significant.
