Abstract
  • The influence of planting patterns and plant spacings on grain yield in field corn (Zea mays) was studied at the Oregon State University Botany and Plant Pathology Field Laboratory near Corvallis, Oregon in 1969. Plant characteristics and yield components studied included plant height, ear height, number of ears, ear weight and weight of 100 kernels. All factors seem to be influenced by spacing rather than planting pattern. Grain yield and plant height increased with increasing plant density until an optimum density was reached. Further increased in density reduced yield and plant height. Ear height tended to increase as plant density increased. Number of ears, ear weight and kernel weight decreased with increasing plant density. Grain yield was directly associated with plant height and kernel weight while kernel weight was directly correlated with number of ears and ear weight.
