Statistics vs statistics: what they mean and how they can influence results locations
Aims

To determine whether sowing direction influences wheat and barley grain yields in the southern grains region.

Key messages
  1. Yields were increased by 0.4t/ha (15%) in barley and 0.2t/ha (10%) in wheat at Horsham in 2014 by sowing east/west. Sowing direction did not alter grain quality. 
  2. Varietal characteristics (maturity, height and growth habit) were not found to influence the yield response.
  3. Similar findings have been found in NSW, in the presence of weeds, and WA, with or without weeds.
