Fig. 8From: Low irrigation water minimizes the nitrate nitrogen losses without compromising the soil fertility, enzymatic activities and maize growthCorrelation between nitrogen content (soil N, NO3−_N leachate, and plant N) and plant enzyme activities under two different irrigation regimes i.e. HW irrigation and LW irrigation. HW and LW represent the irrigation water at the rate of 80 and 60% of field capacity and GOGATBack to article page
