Response of Cottom (Gossypium hirsutum) to Flame Cultivation

摘要

Field studies to evaluate the response of cotton to flame cultivation were conducted in 1994, 1995, and 1996. Flame cultivation at different liquid propane-gas (LP-gas) pressure settings (100 and 175 kPa) with or without watershield protection was applied to cotton at two stages of growth (20 to 25 cm and 40 to 45 cm tall). In 1994, younger cotton was more susceptible to flame cultivation than older cotton, and flaming at an LP-gas pressure of 175 kPa without watershield protection increased plant injury regardless of growth stage, whereas injury was not evident in 1995 and 1996.
