Actual and changes in Mn concentrations (from month 0) in leaf 1 of coconut palms that were treated with manganese sulfate via soil application, petiole injection, or trunk injection. Means with different letters following are statistically different at the P = 0.05 level based on the Waller-Duncan k-ratio method. (n = 10)
