The primary objectives of this study were to: (1) obtain an estimate of the degree to which inter-plot competition exists in forage sorghum yield trials; and (2) provide a basis for suggesting corrective measures. The row arrangements required to achieve the primary objective provided an opportunity to study the response of forage sorghum to different row spacings.
The elimination of inter-plot error, boarder effect, is essential to proper interpretation of data from experimental agronomic units or plots. Economics either from the cost of labor aspects often determine plot size. Frequently forage sorghum, Sorghum vulgare (Pers.) yield influence of tall, (T) or short (s) growing varieties on neighboring plots of the opposite height character were examined during 1963, 1964, and 1965 at Lincoln, Nebraska and Manhattan, Kansas. Tests were established to measure the interactions of these height variables with row spacing and orientation and soil moisture conditions.
