Pea yields on the prairies are not consistent in amount from year to year due to stress in the growing season. Pea yields are substantially reduced in warm summers. A preliminary analysis of the check varieties, as well as newly released varieties (cultivars) from the Saskatchewan and Western Canada Cooperative pea yield trials (2000 to 2009) shows that days to maturity and length of reproductive growth are both reduced in warm or dry summers, resulting in low yield. With a warming climate, the pea crop is going to be stressed more often, resulting in shorter times of growth and substantial reductions in yield amount and quality. An analysis of the COOP yield trials should be completed by late 2010.
The objectives of the Pulse Research Group Physiology Program is to investigate whole plant and field responses of crops, particularly pulse crops, to nutrient, water and weather. To understand and improve yield formation in pulse crops in a warming climate. To investigate and improve nitrogen ... [more]
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]
