Abstract

The effect of five N top-dressing rates (0, 50, 100, 100+50, 100+100 kg ha -1) on the yield and grain protein content of winter wheat was examined in wet and dry years on loam and clay soils. Rainfall deficiency in the winter months (Dec.-Feb.) led to a lower soil NO 3-N content in late winter. The total quantity of soil nitrate-N and mineral fertiliser N was more closely correlated with the yield in the wet year on both loam and clay soils. In the wet year the reduction in the protein content could be counteracted by lower N doses on clay soils than on loam soils, which had poorer water retention.
