Integrated crop-N system management to establish high wheat yield population

It is essential to identify the main components that limit crop yield to achieve high crop yields. We collected data from 156 experimental field plots over six crop seasons to determine the degree to which wheat yield is limited by spike number and to further understand the effects of different sowing dates, seeding rates, and nitrogen (N) management on population development and yield. High yields in plots (>8.5 t ha−1) were attributable to...
