The effects of drainage on the growth and yield of winter wheat established on restored opencast land were studied within a rotation experiment over a period of four years. Previous cropping significantly influenced yields during the third and fourth seasons of the trial. As a result of drainage, grain yields were considerably improved, largely due to increased leaf canopy development, particularly during early spring. Higher concentrations of extractable soil nitrogen, coupled with a more extensive root system, were largely responsible for enhanced nitrogen uptake.
