A field experiment was conducted on make to evaluate the nitrogen losses from arm and calcium ammonium nitrate (CAN),each ® 150kg N ha'applied all at sowing ,1/2 at sowing + 1/2 with 2nd irrigation (28 days after sowing) and 1/3 at sowing + 1/3 with 2nd irrigation + 1/3 at tasseung (70 days after sowing), Prior to sowing and after harvesting the crop, soil samples were collected from each plot at 0-30, 30-60, 60-90, 90- 120 and 120-150 cm depths to fallow nitrate movement in soil profile. N(h-N concentration was higher id plots which received all urea and CAN 0 sowing, h was followed by two splits and three splits of either urea or CAN in descending ord
