  33. Summary ----- Single rotation, 7-year cycle 2000 • Grass-clover sown in autumn – red clover • Winter wheat 5.9 t/ha, triticale 7.5 t/ha • Potatoes, 32.7 t/ha Tuber size - good • Winter oats 5.8 t/ha. Spring 4.6 t/ha. • Lupins 2.4 t/ha • Spring barley 4.5 t/ha • Cultivar evaluation -- Teagasc & DAFF

  34. Conclusions ----- • Winter wheat -- no major production problems. Good yields. • Potatoes – weeds ! Yield, Harvest early August. Suitability ! • Oats - yields good. Sow late-Oct / early-Nov. • Lupins Totally unsuited. • Spring barley. Should do better with lupins gone • Cultivars. Potato – blight and slug resistance. Cereals cultivars. • Nutrients No major decline or depletion. Monitor.
