From: Low irrigation water minimizes the nitrate nitrogen losses without compromising the soil fertility, enzymatic activities and maize growth

Fig. 2

Effect of the interaction between nitrogen dosages and irrigation regimes on the activities of (a) nitrate reductase (NR) NR, (b) nitrite reductase (NiR) NiR, (c) RubisCoRubisco, (d) glutamine synthase (GS) GS, (e) glutamate dehydrogenase (GDH) GDH, and (f) glutamate synthase (GOGAT). The nitrogen treatments are control (0), 200, 250, 300 and 350 kg N ha− 1. The number of observation (n = 16) and HW and LW represent the irrigation water at the rate of 80 and 60% of field capacity
