The beneficial residual effects of the previous regular applications of sodium chloride fertilizers on mature coconuts were evaluated in a long‑term experiment conducted in an inland Tugbok soil (typic Tropudalfs) of Davao, Mindanao (Philippilines). Sodium chloride (common salt) at increpasing rates of 0.0, 0.88, 1.76, 3.52. and 7.04 kg/tree per tree was tested.,
At higher rates of NaCl fertilizer (1.76‑7.04 kg/tree per year) applied regularly for 5 years, the residual respofise in terms of nuts and copra yield tended to, occur for a longer period of 5 years. Except soil Na, soil. properties were not significantly affected by NaCl application.
Implications of the findings are discussed in relation to sound coconut crop agronomy and soil management.
