Salt stress is the second most widespread soil problem after drought in arable crop production worldwide. Excess salt in soil adversely affects plant growth, development, and productivity when osmotic stress reduces water uptake by roots. This publication provides standard operating procedures for managing crop phenotyping in controlled/semi-controlled environments and natural field conditions. As a comprehensive reference, the publication will support IAEA Member States in the application of these procedures to increase the productivity of arable food crops to help withstand the impact of climate change on agriculture.
