A field experiment with triticale cvs. Tango and KG-20 was set up on acid soil (pHH2O 4.2) to evaluate the effect of different rates of mineral (N120; P80, 160; K53) and organic fertilisers (manure) and liming on grain yield and yield components. Both mineral and organic fertilisation and liming induced a significant increase in grain yield components, particularly grain number/weight per spike and spike number / square meter, resulting also in a significantly higher grain yield in fertilised treatments. Soil liming and organic fertilisation had a higher effect in grain yield as compared to the increased P rate, mostly due to P immobilisation in the highly acid environment. In regions where liming is economically acceptable, it should be used in growing triticale on highly acid soils to increase pH above the suboptimal level (pH 5.0) for enhanced yield potential.
