Abstract:

A field study was conducted during 1997 and 1998 summer season to find out the effect of 4 irrigation schedules, based on actual evapotranspiration (ET), and 4 rates of nitrogen on maize. Averaged over the two seasons, the response of total dry matter (TDM) and I3 (-8 bars) based on crop evapotranspiration was greater than control (I1) or I2 (-4 bars) irrigation schedule. The study showed that seasonal water requirements of the maize crop under irrigated conditions vary from 181 mm to 220 mm after due account of rainfall. Average response varied at 5.90 gm-2mm-1 and 2.37-3.01 g mm-2mm-1 for TDM and grain yield, respectively.
