Short Communications


Two experiments were carried out with coconut seedlings grown in polybags filled with soils from maritime and forest environments. Salination treatments of 0, 2, 4, 6, 8, 10 and 12 g of common salt were applied to each polybag seedling fortnightly. The youngest open leaf, which was next to the spear leaf, of each seedling was sampled for chemical analysis after 12 months of seedling growth. Na and Cl content of leaf increased appreciably as a consequence of increased salt application while N, K, Ca and, to a lesser extent, P decreased with salinity. N and K content were higher in leaves of coconut plants grown in the forest soil while Na content was higher in those grown in the maritime soil. Antagonistic effects also occurred between Na and K, and Ca and P in both soils.
