Description

Do early season problems 'disappear' in corn7 Plant-to-plant and in-field variability was a concern across numerous corn fields in 2007. In addition, fields had uneven seeding depths, shallow nodal root systems, sidewall compaction, and other problems were common. We will discuss the importance of uniformity in fields relative to yield partitioning and yield determination in corn. First we present a primer of early season root systems and then we present a list of 9 early-season management/environmental factors that affect plant-to-plant and in-field variability and reduce yield potential. Anything that disrupts early-season growth can have a negative impact on yield. Here we will discuss only nine.
