Leaf area was measured for soybean in the growing season of 2018 at the Agrometeorological Research Station, Keszthely, Hungary, in evapotranspirometers (unlimited watering) and on the field with natural water supply (rain-fed plots). The experiment was carried out with two varieties (Sinara and Sigalia). During the investigation period leaf area was measured weekly. The results showed that there was no significant difference in leaf area between the two varieties. Optimum water supply for Sigalia resulted in significantly higher leaf area compared to natural water supply.9ensoybeanGlycine max L.leaf areaunlimited wateringnatural water supplyidegen nyelvű peer review publikációtudományterületek::környezettudományoktudományterületek::növénytudományok
