Different developmental stages of foxtail millet (Setaria italica L. BEAUV.) were studied during dry seasons in 1989 and 1990. Two cultivars, Bogra-1 and Titas, were employed in the study. Twelve morpholog-ically different and distict growth stages were identified, viz, seedling emergence, 3-leaf, 5-leaf, crown root initiation (CRI), maximum tillering (MT), panicle primordium initiation (PPI), flag leaf, booting, heading, milk, dough, and physiological maturity. Bogra-1 took 11 and 8 days more to attain physiological maturity than Titas in 1989 and 1990, respectively. In both years, growth rate was the highest at heading stage in Bogra-1 and at PPI stage in Titas, although leaf area in both cultivars was maximum on 41 days after emergence (DAE) of seedlings which was around PPI stage. Bogra-1 produced higher grain yield than Titas.
