Water and nitrogen are two important resources for crop production. Yields in maize respond
positively with an increase in the amount of water and nitrogen applied and reaches the plateau
at their optimum doses. Hence, the present study was under taken to examine the appropriate
irrigation schedule through drip as well as nitrogen application rate.
