Comparison of leaf area of soybean under unlimited watering and rain-fed condition
Keywords:
soybean, Glycine max L., leaf area, unlimited watering, natural water supplyAbstract
Different methods have been used to measure leaf area of soybean (Glycine max L.). In this study, high resolution photos of soybean leaves were processed using a histogrambased threshold method. 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.
