Fig. 2: Distribution of partial Land Equivalent Ratio (pLER) and the importance of moderating factors shaping it.
From: Ecological drivers of intercropping performance for enhanced global crop production
a Histogram of relative yield (pLER). b Importance of moderators in determining the yield change of the intercropping system. The dashed line, solid red line and the shaded area in a represent pLER = 1, the mean effect size and the 95% bootstrap confidence intervals for the mean effect size. The numbers denote the total observations with the numbers of studies in parenthesis. The relative importance in (b) is quantified based on metaforest model and expressed as percentage relative to the top variable ‘Relative Density’, which is set to 100%.
