The effects of plant density and tiller removal were determined on yield and agronomic characters of 3 sweet corn cultivars during the growing periods in 1997 and 1998 in Isparta plain in Turkey. Ear yield varied depending on cultivars and the highest ear yield was obtained for cv. Merit in 1997 and 1998 (13.8 and 11.8 t ha-1, respectively). Number of tiller plant 1, ear length, ear diameter and filled ear length decreased in high plant density (9.5 plants/m2). Plant height and ear yield increased as the plant density increased. While tiller removal did not affect statistically significant any characters except the filled ear length in sweet corn varieties in 1997. It reduced plant height and ear yield in the second experimental year.
