Abstract

Development was followed in Connecticut and Maryland. Germination of yellow foxtail (Setaria lutescens (Weigel) F. T. Hubb. occurred over a long time period. Tillering of the developing plants was affected by spacing between plants and location. The average number of tillers in Maryland was 75 for plants spaced 12 in. apart and 26 for plants spaced 2 in. apart. In the greenhouse under short day conditions seed heads were readily produced. Under continuous light no seed heads formed. Giant foxtail (S. Faberii Herrm.) followed a similar growth pattern but the plants were larger and formed fewer tillers. Growth of both species was severely affected by shading. Both species rooted from cuttings.
