Fig. 3. Effects of manure application frequency (before first crop, F1, before first and second crops, F1 + F2, or before all three crops, F1 + F2 + F3) and rate (recommended rate, R1, or twice the recommended rate, R2) on Harvest 3 (sorghum ratoon) dry matter (DM) and N uptake (within a soil type and application rate, application frequency bar means having different lowercase letters differ at P < 0.05; within a soil type and application frequency, application rate bar means having different uppercase letters differ at P < 0.05).
