Yield varied from 0.76 to 4.03t/ha across the paddock according to the yield map. Most of the yield variation was due to soil type with higher yield on the limey rising ground and the lower yield on the clay soil type. On average, there was no positive response to cultivation on yield (Table 2 and Figure 1). Assessment of impact on Annual Ryegrass populations found Ryegrass numbers to be low across the paddock (<1/m2) and there was no difference between treatments. Most of the ry |
