ABSTRACT
This study was conducted to investigate the effects of different Nitrogen (N) application rates (150, 200, 250, 300 and 350 kg N ha-1) and different Intra Row Spaces (IRS) (140 mm=102 040 plants ha-1, 180 mm=79 370 plants ha-1, 220 mm=64 930 plants ha-1, 260 mm=54 940 plants ha-1, 300 mm=47 620 plants ha-1) on fresh ear yield of sweet corn which was grown as second crop in south-eastern of Turkey during 1998 and 1999. N, IRS and N x IRS interaction were significant (p<0.01) for fresh ear yield. The highest fresh ear yield (16.01 t ha-1) was obtained from 300 kg N ha-1 x 220 mm (64 930 plants ha-1) IRS application. Increasing nitrogen applications increased fresh ear yield.
