520 _aThe effect of potassium (0, 50, 100 and 200 mg/pot) was studied on growth characteristics and nitrate reductase activity in maize (Zea mays) seedlings during water stress and subsequent recovery. In irrigated plants K('+) increased the rate of leaf area expansion, leading to increased leaf area per plant. Increased leaf area was associated with decreased chlorophyll content. Water stress (-15 bars) enhanced the stomatal resistance of leaves which was further accentuated by K('+) application. Nitrate reductase activity rose in irrigated plants 24 h after K('+) application. Subsequently, as water stress developed, K('+) helped to maintain higher NR activity
