Experiments were conducted at the Tamil Nadu Agricultural University, Coimbatore for four consecutive seasons during 1989 kharif to 1990 kharif to elucidate the response of nitrogen and irrigation levels under sole and intercropped maize Zea mays L. The first set of experiment showed a linear response of yield with an increase in nitrogen levels. The second set of experiment clearly revealed that the crop responded upto 187.5 kg N ha in both sole and intercropped situations. The intercrop did not cause either competitive depression or nitrogen transfer any level of irrigation or nitrogen. Irrigation at an IW/CPE ratio of 0.75 significantly increased the growth and yield of maize at all the levels of nitrogen and systems of cropping.
