Phosphorus Placement Effects on Phosphorous Recovery Efficiency and Grain Yield of Wheat under No-Tillage in the Humid Pampas of Argentina
Figure 5
Available soil P-Bray at tillering (0–10 and 10–20 cm) affected by placement method and P rate. Means followed by the same letter are not significantly different from each other based on the LSD 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. P-B: phosphorus broadcasted. P-L: phosphorus banded at sowing.
