Abstract:

A field study was conducted in Faisalabad, Pakistan, during the 1997 and 1998 summer seasons, to determine the effect of 4 irrigation schedules (control, -4, -8 and -12 bars), based on actual evapotranspiration (ET) and 4 N fertilizer rates (0, 100, 200 and 300 kg/ha) on maize cv. Golden. Averaged over the 2 seasons, the response of total dry matter (TDM) and I3 (-8 bars) based on crop evapotranspiration was greater than the control (I1) or I2 (-4 bars) irrigation schedule. The seasonal water requirements of the maize crop under irrigated conditions varied from 181 mm to 220 mm after due account of rainfall. The average response varied from 5.90 and 2.37-3.01 g/mm2/mm for TDM and grain yield, respectively.
