Meta‐analysis of salt stress response of yield and growth in three experimental settings and across different levels of salinity. Ratio of grain yield (per plant or per hectare) in saline stress conditions to control conditions (A). Ratio of shoot dry weight in saline stress conditions to control conditions (B). Ratio of root dry weight in saline stress conditions to control conditions (C). Field: black squares; pots outdoors: purple circles; pots in a greenhouse: blue triangles. Number of data points in each bin of salinity presented in the tables within each plot; statistical analysis for pair‐wise comparison of settings included at the top of each plot, obtained with Mann–Whitney U test for A and B, permutation t test for C; error bars represent the standard error.
