A field experiment with four irrigation and four nitrogen treatments was carried
out with wheat (cv HD 2932) for two rabi seasons, 2009-10 and 2010-11 at ICAR-Indian Agricultural
Research Institute, New Delhi to quantify the water and nitrogen use efficiencies under
differential water and nitrogen levels. Responses of water-use efficiency (WUE), nitrogen-use
efficiency (NUE) and wheat yield to variable water and nitrogen levels were investigated. Yield and
NUE are significantly affected (P ≤ 0.05) by the different water and nitrogen levels. Under low
water level condition along with no nitrogen stress resulted in only 5% decrease in yield compared
to the highest yield but it had increased NUE from 34 to 38%. Therefore, low water stress can be
allowed which can result in higher NUE and non-significant decrease in yield. The study revealed
the lower water stress resulted in higher NUE, higher water stress resulted in decline in NUE.
