In Australia, Ground Cover reported that a researcher is investigating whether Central Queensland’s warmer nights are behind its lower sorghum yields.
A Central Queensland researcher is examining the effects of elevated night-time temperatures on sorghum this summer to understand how these conditions affect grain yields, according to the report.
Doug Sands, a Principal Research Agronomist at the Queensland Department of Primary Industries (DPI), has launched a 2-year pilot project to explore how higher minimum night-time temperatures affect sorghum respiration and consequently grain yield.
The research stems from grower feedback through GRDC’s National Grower Network, where concerns about low sorghum yields in Central Queensland were raised.
Sands is evaluating various sorghum hybrids to identify a select few for testing in the heat chambers in summer 2026-27. This research aims to identify any genetic influences on minimum night-time temperature respiration responses.
