Corn growth is influenced by cultural practices and available natural resources. The rate of growth and development changes during the season (fig. 1.1). In South Dakota, water and nitrogen (N) are important resources that limit yield. Other factors that reduce yield include disease, insects, weeds, and deficiency of other plant nutrients. For example, disease and insect infestations can reduce water and nutrient uptake or severely damage the plant to the point of yield loss. Weeds compete with the crop for water, nutrients, and light. Stress from temperature and water extremes affects nutrient availability, often increasing pest population and occurrence and ultimately reducing plant growth.
