In field trials in 1975-7 on good rye soil in Poland, 4 spring wheat cv. were given 60, 100 or 140 kg N/ha and were compared in terms of plant and ear number/msuperscript 2, tillering, 1000-grain wt., number of grains/ear and baking quality. The effects of different rates of applied N varied between yr according to climatic conditions. 1000-grain wt. decreased with increasing N fertilizer and this appeared to affect grain yield which followed the same overall pattern, although there were some differences between cv. The rate of applied N did not affect the number of ears/msuperscript 2. Total grain protein content and yield increased with increasing N.
