Abstract

Freshly harvested Drummond rattlebox [Sesbania drummondii (Rydb.) Cory ♯3 SEBDR] seed germinated best after 2.5- to 4-h acid scarification in concentrated sulfuric acid. Optimum temperature for germination was 30 to 35 C. At 10 and 45 C no germination occurred for up to 7 days. Six days after planting in a silt loam soil there was 95 and 80% emergence of Drummond rattlebox from depths of 0.5 and 1 cm, respectively. No emergence was observed from depths of 11 cm or greater 12 days after planting.
