Seed soaking in and/or foliar spray by silicon or proline effects on nutrient content (i.e. N, P, K, Ca, and Na) and K+/Na+ ratio of salt-stressed maize plants in two growing seasons. Data are means (n = 5) ± SE. The same letters in each column indicate no significant differences according to the LSD test (p ≤ 0.05). TW tap water, Si silicon, Pro. proline.
