Impact of excess moisture due to precipitation on barley grain yield in the Canadian prairies

In the last decade the majority of insurance claims from barley farmers were based on excess moisture problems. Analysis on the effect of monthly accumulated precipitation data (May - July) on crop losses between 2005 and 2016 with regional barley yield data collected from rural municipalities and agricultural divisions for Manitoba, Saskatchewan and Alberta was conducted. A significant negative relationship with total precipitation during May to June was observed. This period coincides with leaf emergence to the booting stage in barley.
