Abstract
An ^experiment on sugarcane intercropping was conducted at the Waimanalo research station of the University of Hawaii during 1993-94. Sugarcane was planted with sweet corn and wheat at N levels of 0, 75, ISO, and 300 kg ha' to study the effects of N and intercropping on growth behaviour, and productivity of sugarcane. The results of the study indicated that the plant height was significantly affected by the cropping systems, at early growth stages, with the tallest plants in cane intercropped with com and shortest in sole cane. Plant height in sole cane continued to he the maximum with 300kg N ha' up to 216 days after DAP. Cane plants in sweet corn were taller at ISO kg N ha'1 at early stages and at 300 kg N ha'1 at later stages of growth. However, cane plants intercropped with wheat were tallest in 300 kg N ha' and shortest in 0 kg N her' at all stages. At early stages ljeaf Area Index (LAI) was higher at 150 kg N ha'1 in sole cane, and later it was maximum at 300 kg N ha'. Leaf Area Index (LAI) in intercropped cane was the maximum at 300 kg N ha'1 and minimum in control. Application of 150 kg N ha1 produced the maximum dry matter (61.72 t ha') and sugar yield (18. XX t ha') in sole cane. Whereas, 300 kg N ha'1 was required to produce the maximum dry matter (62.49, and S7.H6 t ha') and sugar yield (15.92 and 14.33 t ha') in cane intercropped with sweet corn and wheat, respectively. Total dry matter and sugar yields increased with increasing N levels from 0 to 150 kg ha' in sole cane. Whereas, both dry matter and sugar yield increased in intercropped cane with increasing N leve
