Quantitative assessment of soybean drought loss sensitivity at different growth stages based on S-shaped damage curve

Crop drought loss sensitivity assessment is fundamental for managing agricultural drought risk. Potted soybean water deficit experiments with different irrigation treatments during two seasons (2015 and 2016) were conducted in China’s Huaibei Plain. S-shaped soybean drought loss sensitivity curves at four growth periods were established, and the sensitivity of seed formation to water deficit during different stages was quantitatively compared....
