Abstract
Field experiments were set up at ADAS Rosemaund (Herefordshire) and Sutton Bonington (Leicestershire) to examine the effects of reducing seed rate on the yield and yield components of 4 varieties of winter wheat, in harvest years 1996-9. Each variety was sown at six seed rates from 20 to 640 seeds m-2 and at 3 sowing dates at ADAS Rosemaund. Sampling, at harvest and at major growth stages, facilitated comparisons of yield, crop growth and yield components. A second series of experiments at ADAS Rosemaund only, investigated interactions between seed rate and variety (using two seed rates and up to 22 varieties).
