Sorghum in the western zone: row configuration x population x hybrid - "Koiwon", Bellata 2014-15 locations
Aims

 To answer some of these questions and provide data for use in modelling the trial outcomes over long-term climatic data sets. 

Key messages
  • In a low-yielding season varying row configuration had no effect on sorghum yield.
  • Yield declined as plant population and hybrid tillering ability increased and staygreen levels decreased.
