Crops with uniform stands have the advantage of producing higher grain yields under good growing conditions and management systems than crops with poor stands. Delayed emergence and complete failure of seed emergence are causes of uneven crop stands early in the season. Determining the correct nitrogen rate for plants of uneven emergence will prove to be beneficial in nitrogen use efficiency and crop yields. The objectives of this study were to determine corn (Zea mays L.) nitrogen responsiveness as a function of interplant competition arising from delayed emergence and to assess nitrogen requirements associated with 3 plant sequences, with and without delayed emergence. These variables were investigated at two experimental sites established in the spring of 2007, near Stillwater, OK at the Lake Carl Blackwell Agronomy Research Farm under irrigation and at the Efaw Agronomy Research Farm in a rainfed environment. Dekalb (DKC 66-23) Bt corn hybrid was planted in early to mid April at a seeding rate of 73779 plants ha-1. Each 2.7 m-row was planted by hand to maintain 18 cm-inter row spacing. A total of 15 plants within row were divided into five 3-plant subgroups. Each subgroup contained three plants, two plants planted on the same day and a delayed plant planted between the two plants. The delayed plants were planted 4, 7, and 10 days after initial planting to simulate various delayed emergence scenarios, as well as receiving varying amounts of by plant nitrogen fertilizer to assess nitrogen response. Evaluation of by plant fertilizer demands to assess nitrogen response will further increase nitrogen use efficiency while facilitating higher grain yields by treating variability in emergence.
