Fig. 2. Visual iron deficiency chlorosis (IDC) scores of soybean planted at 432 000 seeds ha–1 and with the addition of glyphosate-susc. soybean or oat. Glyphosate-susc. soybean was added at the rates of 124 000 or 247 000 seeds ha–1 (+124 K susc. and +247 K susc., respectively). Oat was added at rates of 19 and 37 kg ha–1 (+19 kg oat and +37 kg oat, respectively). Figures represent studies at two chlorotic environments in 2002 (Environments 1 and 10). Iron deficiency chlorosis scores were recorded on five dates. n = 6 ± SE.
