Flaming treatments were applied utilizing a custom-built research flamer mounted on the back of a four-wheeler driven at a constant speed of 6.4 km h−1. The propane doses tested were 0, 13, 24, 44 and 85 kg ha−1. ![]() We initiated a 2-year field study at the Haskell Agricultural Laboratory of the University of Nebraska, Concord, NE using five propane doses applied at four growth stages of VC (unfolded cotyledons), VU (fully unrolled unifoliate leaves), V2 (second trifoliate stage) and V5 (fifth trifoliate stage). The objective of this study was to investigate the response of soybean to broadcast flaming as influenced by propane dose and crop growth stage. Propane flaming could be an additional tool for weed control in organic soybean production. ![]() Weed management is a major constraint in organic crop production.
