Phosphorus Placement Effects on Phosphorous Recovery Efficiency and Grain Yield of Wheat under No-Tillage in the Humid Pampas of Argentina

Figure 3

Phosphorus recovery efficiency (PRE) in dry matter (DM = grain + residues) and grain of  NT wheat as affected by placement method and P rate. Means followed by the same letter are not significantly different from each other based on the Duncan test (0.05). Phosphorus response is compared using 25, 50, and 150 P rates (gray). Phosphorus placement method is only compared at 25 and 50 P rates (black). P-B;  phosphorus broadcasted. P-L:  phosphorus banded at sowing.
