Fig. 1. Effect of soil extractable Cl content (0.0- to 0.2-m layer) on relative grain yield of wheat in 10 sites from the sandy Pampas region fertilized with Cl. Each point is the average of two Cl fertilizer sources (KCl and NH4Cl) and two foliar fungicide treatments. The solid line shows the quadratic fitted relationship between variables for the Cl unfertilized treatments.
