Morphology and Seed Yield of Drought-Stressed Soybean as Affected by H2O2 Spraying

Abstract
Soybean is considered as one of the most important legumes because of its high content of both proteins and oil, however, it is very sensitive to drought stress which was increasingly recorded over the past decade. Plants respond to drought by several changes on the physiological and molecular levels and by endogenously changing the concentrations of certain substances like reactive oxygen species (ROS). An experiment was conducted to study the effect of spraying soybean plants at two different stages with hydrogen peroxide (H2O2) on some physiological traits in addition to the final seed yield in Debrecen, Hungary in 2018. Results obtained showed that plants exhibited better physiology when sprayed with H2O2 at R2 stage which, in part, resulted in better seed yield. However, re-spraying the plants at R4 stage did not result in further enhancement. It was concluded that pre-drought H2O2 application might be a beneficial strategy in soybean production to ameliorate drought stress influence.
