The effect of sowing date and fungicide application on grain yield of canola – Alma Park 2015

Abstract

Key findings »» Sowing date and varietal phenology both affected the exposure of canola to rain days and potential disease infection. »» Early sowing increased the level of pod blackleg infection. »» Early sowing increased sclerotinia infection in the early flowering variety Hyola® 575CL but not in the slower variety Pioneer® 45Y88 (CL). »» Grain yield was higher from the later sowing date (22 April) than the early sowing date (7 April). »» Grain yield was closely correlated to total biomass accumulation, which was greater from the 22 April sowing time than the 7 April sowing time.
