Wheat grain yield response to elevated temperature and nitrogen locations
Aims

To study the effect of elevated temperature, sowing time, variety, and N rate on wheat yield.

Key messages
  • Elevated temperature reduced yield by 0.3 – 0.4 t/ha per degree (°C) higher during pre- and post-flowering. •
  • The effect of temperature was offset by grain number per m2 .
  • Higher N rates may partially mitigate the effect of elevated temperature..
