Effects Of Irrigation With Saline Water, And Soil Type On Germination And Seedling Growth Of Sweet Maize (Zea Mays L.)
Germination and early growth of maize Sweet Maize (Zea mays L.), var.
(SEL. CONETA) under irrigation with saline water were investigated in a pot
experiment with different soil types. Seven salinity levels of irrigation water
up to 12 dS/m were used on a Clay soil (C) and a Sandy-Loam (SL).
Emergence of maize was delayed under irrigation with saline water, and the
final percentage of germination was reduced only at 8 dS/m or above.
Seedling shoot and root growth were reduced starting at 4 dS/m of irrigation
water. Salts accumulated more in the C soil but reductions in final
germination rate and seedling growth were larger in the SL soil, although
differences were not always significant. Data indicate that germination is
rather tolerant to salinity level in var. SEL. CONETA whereas seedling
growth is reduced at moderate salinity levels, and that soil type affects plant
performance under irrigation with saline water
