Linking yield impact to changing climate for wheat, pea and canola by cropping districts

Overview
2009 to 2011

A detailed analysis of pea, spring wheat and canola and other praririe crops is part of a current collaboration (2009-2011) with Dr Lynn Seymour, Department of Statistics, University of Georgia, USA. The aim of this project is to explore and relate the variability in yields for Saskatchewan, Alberta and Manitoba crop districts to 30 years of weather.  The objectives are to identify the effect of changed weather on crop adaptation, identify the threshold temperatures and rainfall requirement for stable yield, and develop a strategy for improving future cultivars to keep pace with climate change.  At the cropping district level, researchers and growers will be able to connect how much change in yield for wheat, pea or canola will result when certain weather measurements deviate from monthly averages or extremes for the actual months within a cropping season.   When we know how yield performs when several weather factors change together, we can change crop management accordingly, and we can provide future varieties that can tolerate a shifting climate.

Pea (Pisum sativum L.) is one of the first domesticated crops, and was the model crop for the foundational genetic studies by Gregor Mendel, which he first reported in 1865. Pea is grown in most temperate regions of the world with annual production over the past decade of 10-12 million tonnes of field pea and 14-17 million tonnes of vegetable pea. Pea belongs to the Leguminosae family and consists of two species, P. fulvum and P. sativum with several ‘wild’ subspecies of P. sativum. Canada is the leading producer and exporter of field pea in the world. Saskatchewan is the leading province in pea production followed by Alberta and Manitoba. ... [more]
