Graduate Student (M.Sc.) Position Influence of inbred vigour on nitrogen fertilizer requirement and risk of environmental loss.
In the seed corn industry there is considerable variation in inbred vigor in terms of seed yield and quality (seed size, cob size, number of kernels per cob etc.) and also plant morphology such as plant height and leaf area. But little is known about N requirement or N content among inbreds with different vigour. Thus, this project will look at industry extremes, so called ‘strong and weak’ inbreds, to determine if they require different rates of nitrogen fertilizer.
