Establishment of Tall Fescue and White Clover: Effects of Seeding Method and Weather1

Richard H. Hart, G. E. Carlson and H. J. Retzer2

We drilled and broadcast-seeded tall rescue (Festuca arundinacea Schreb.) and white clover (Trifolium repens L.) on three soil types, on 29 dates in 1963 and 1964. Tall rescue yields of the spring after seeding were generally higher from drilled than from broadcast stands. Although drought in the spring of 1965 reduced yields from most of the 1964 seedings, rescue yields were mainly limited by soil moisture supply immediately after germination. If drought occurs in this critical period, the rescue should be reseeded, because future forage yields will be greatly reduced. However, irrigation during this period should greatly increase potential yields the following year. The amount of white clover in the stand was limited by moisture and competition with rescue; there was more clover in broadcast stands, where competition with rescue for light and moisture was less severe, and in stands planted in summer, when more light could penetrate the stand.

Key Words: drilled vs. broadcast • yield prediction
