Abstract
An experiment was conducted at the Waimanalo Research Station of the University of Hawaii, Honolulu, to study the effect of nitrogen and inter-cropping on agronomic traits and productivity of sweet con:, during 1993-94. Sweet cons was planted as a sole crop and as an inter-crop in between sugarcane rows at N levels of 0, 75, 150 and 300 kg ha'. The results of the study indicated that cropping system did not affect number of roil plane, fresh weight ear', and number of groins ear'. Total fresh weight of ears ha-', was higher in inter-cropped corn. Ears plant', in both cropping systems were the maximum at 300 kg N Fresh weight ear' increased signifkantly up to 150 kg N in sole sweet corn and up to 300 kg N ha' in inter-cropped sweet corn. Grains ear' were similar at various applied N levels in sole corn, whereas, in inter-cropped sweet corn it increased with increasing N levels. Total fresh weight of ears he was the maximum at 300 kg N ha' (16.41 t ha-' in sole crop and 21.11 t has in inter-cropped sweet corn).
