In field trials at Cumra, Turkey, in 1988-89, maize hybrid TTM-813 was grown at row spacings of 30, 50 or 75 cm, with 0, 3, 6 or 9 kg cycocel ha applied at emergence or when plants were 15-20 cm tall. Plant density and cycocel application rate had significant effects on grain yield, but application date did not. There were significant interactions between plant density and application rate, and plant density, application rate and application date. Increasing application rate generally decreased plant height and leaf length of the first ear but increased ear number/plot, grain number/ear and 1000-grain weight.
