Management for Maximum Economic Yield of Open Pollinated and Hybrid Canola

This research was initiated to determine whether higher yielding hybrid rapeseed (canola) varieties require a higher level of management to express higher yields, compared to older open pollinated canola varieities.

IPNI-1999-CAN-SK24

Many of the agronomic practices used for canola production were developed prior to 1980, although they have been updated somewhat with new information generated since that time. The check variety in use in 1980 was Regent. Based on relative variety comparisons, some that are currently being grown have much higher yield potential. Read more

Interpretive Summary

Management for Maximum Economic Yield of Open Pollinated and Hybrid Canola, 2001 Hybrid varieties of canola are new to farmers in western Canada, and there is a lack of understanding as to the level of management and inputs required to optimize yield relative to established open pollinated varieties. Inputs that are seen as critical to optimizing yield include seeding rate, fertility level, and fungicide use for control of white mold (sclerotinia spp. ).

Management for Maximum Economic Yield of Open Pollinated and Hybrid Canola, 2000 Hybrid varieties of canola are new to farmers in western Canada, and there is a lack of understanding as to the level of management and inputs required to optimize yield relative to established open pollinated varieties. Inputs that are seen as critical to optimizing yield include seeding rate (crop establishment), fertility level (N, P, K, and S), and fungicide use for control of white mold (sclerotinia spp. ).
