The Gowth and Leaf Area Development of Finger Millet Under Salt Stress

The high yielding Kenyan cultivar of finger millet (Eleusine coracana L. Gaertn, "Ekalakala-1"), was grown in pots and subjected to substrate salt levels ranging between 0 and 1.2 s m**-1 electrical conductivity (EC). The plants were raised for a total of 58 days after sowing (DAS). The se...

Summary:The high yielding Kenyan cultivar of finger millet (Eleusine coracana L. Gaertn, "Ekalakala-1"), was grown in pots and subjected to substrate salt levels ranging between 0 and 1.2 s m**-1 electrical conductivity (EC). The plants were raised for a total of 58 days after sowing (DAS). The seedling dry weight and height, number of live leaves and their areas were determined at various dates during growth. The medium (0.8 s m**-1) and high (1.2 s m**-1) salt stress significantly reduced the percentage seed germination, relative growth rate and height of seedlings. It was concluded that the cultivar has a high physiological resistance to salt stress but that, for agricultural purposes, economic production may only be achieved if the substrate has a saturated extract with and electrical conductivity at or below 0.8 s m**-1.
