Sorghum growers weigh up January heatwave risk

Plain text source: 
Sorghum growers weigh up January heatwave risk.. Sorghum growers looking to plant in November are being urged to weigh up the risk of excessively high temperatures occurring in January and coinciding with critical development phases of crops... The research found the most severe impacts on yield occurred when high temperatures around flowering reduced the viability of sorghum pollen causing reduced seed set and yield loss, according to Professor Graeme Hammer, Director of the University of Queensland's Centre for Plant Science at the Queensland Alliance for Agriculture and Food Innovation (QAAFI)...
