With the advent of more readily accessible high clearance application equipment, there has been considerable discussion in regards to the use of high clearance application equipment to deliver crop inputs to corn at times which have previously not been as feasible (ie. taller corn), particularly with the aims of pushing yields through promoting greater kernel set. Intensive, unconventional management practices such as these are often promoted by corn-yield contest growers for breaking through ‘yield barriers’. This project has been developed to investigate the influence of application timing of foliar fungicides, foliar nitrogen fertilizer, and soil surface applied fertilizers on kernel set and yield in grain corn.
