Under Concurrent Drought and Herbivory, Drought Dominates Herbivory on Morpho-Physiological Responses in Soybean.

ABSTRACT: Drought and insect herbivory constantly threaten yield and productivity of crops like soybean (Glycine max). Recent advances in crop science have examined these stressors either individually or sequentially, but concurrent interactions have not been well understood. Therefore, using two soybean cultivars (Blackhawk- drought susceptible and Magellan- drought tolerant), we investigated how concurrent drought and herbivory by the fall armyworm (Spodoptera frugiperda, FAW) affect soybean and FAW traits. Four treatments drought-D, herbivory-H, drought × herbivory-DH, and well-watered-WW were imposed at the third-trifoliate stage (V3) for a week. During the treatment period, daily measurements of net photosynthesis rate, stomatal conductance, transpiration rate, and soil moisture were taken, whe
