Abstract

A field trial was conducted on irrigation schedules and nitrogen levels in maize grown on light red sandy soils of A.R.S., Garikapadu during rabi 1999-2000 to 2001-02 in split plot design. The treatments consisted of four irrigation schedules (0.6, 0.8, 1.0 IW/CPE ratio and 5 irrigations at crop phenological stages in main plots and 5 nitrogen levels (0, 60, 120, 180 and 240 N kg/ha) in sub plots. Grain yield, WUE and nitrogen use efficiency and water requirement were worked out. Maximum grain yield was recorded when the irrigation was scheduled at 1.0 IW/CPE and nitrogen fertilized upto 240 kg/ha.
