Description
The central Andes of Peru are characterised by moderately acid soils, a pronounced dry season of 4-5 months and temperatures that decrease as night frosts increase with altitude. Above an altitude of 3200 m asl, the proportion of pastures in land use increases. However, native pastures lack sufficient quality and quantity to maintain· animal production, particularly in the dry season. Where irrigation is not available, introducing annual legumes may be an option to improve native pastures. In a trial to test adaptation of subterra.nean clover (Trifolium subterraneum L.), 5 Australian cultivars were sown at 4 different altitudes between 3300 and 4150 m, and with 4 sowing dates between September and December. Early sowing and optimal altitudes (between 3600 and 3800 m) gave higher forage dry matter and seed yields. The most promising cultivars were Clare under suboptimal, and Howard and Woogenellup under optimal conditions.
