QUIZ – Seeding delays Madeleine Baerg May 11, 2022 Three questions on seeding into moist soils, appropriate seeding rates and yield for late-seeded canola. 1. Packing pressure appropriate for the soil conditions is one way to increase canola seed survival. Which one of the following is the true statement:In moist to wet soil conditions, reduce packing pressure to limit hard crusting.In moist to wet soil conditions, increase packing pressure to squeeze moisture away from the seed row.In dry conditions, reduce packing pressure so moisture can infiltrate through soil pores.In dry conditions, increased packing pressure will reduce yields due to compaction. 2. A scenario: Canola seed has a thousand seed weight (TKW) of 6 grams. The farmer wants a stand of 6 plants per square foot. At 50 per cent seed survival – which is common – the seeding rate required to hit that target is 6.9 lb./ac. What seeding rate (lb./ac.) is required if the farmer can increase seed survival to 80 per cent?3.54.34.911.5 3. Based on Manitoba crop insurance data from 2010-2019, what is the percent-of-average yield for canola seeded the first week of June?708090100 Loading...
