Data from: Multifaceted functional diversity for multifaceted crop yield: towards ecological assembly rules for varietal mixtures

<p>Data and code for the study &quot;Multifaceted functional diversity for multifaceted crop yield: towards ecological assembly rules for varietal mixtures&quot;</p> <p>Two data files are available:</p> <ul> <li>&quot;CWM_D.csv&quot; contains one row per experimental plot with community-weighted mean (CWM) and Rao quadratic diversity (D) indices computed on the 19 functional traits.</li> </ul> <p>The first two columns (&quot;genotype_1&quot; &amp; &quot;genotype_2&quot;) are the identity of the two genotypes in the plot, which are identical in single-variety plots. The third column (&quot;assoc&quot;) refers to the plot type: single-variety (&quot;M&quot;) or mixed-variety (&quot;P&quot;) plot. Then, all trait CWMs and Ds are reported as &quot;CWM_trait_name&quot; and &quot;D_trait_name&quot; , respectively. For single-variety plots, only CWMs are reported but in this case they correspond to unweighted-averaged trait values across replicated measurements within plots. Root trait names are followed by &quot;sem&quot; or &quot;adv&quot; depending if they were measured on seminal or adventitious roots. Reported traits are: &quot;Angle_aer&quot; (Aerial angle, &deg;), &quot;Angle_root&quot; (Root angle, &deg;), &quot;Diam_sem/adv&quot; (mean root diameter, mm), &quot;SRL_sem/adv&quot; (specific root length, m/g), &quot;RTD_sem/adv&quot; (root tissue density, g/cm3), &quot;RBI_sem/adv&quot; (root branching intensity, nb of root tips/cm), &quot;RLD_sem/adv&quot; (root length density, cm root/cm3 soil), &quot;Till_nb&quot; (tiller number per capita), &quot;Ear_bio&quot; (early biomass per capita, g), &quot;SLA&quot; (specific leaf area, m&sup2;/kg), &quot;LNC&quot; (leaf nitrogen content, %), &quot;Height&quot; (plant height, cm), &quot;Heading&quot; (heading date, Growing Degree Days), and &quot;Maturity&quot; (maturity date, Growing Degree Days).</p> <ul> <li>&quot;RAW_RYT.csv&quot; contains one row per experimental plot with absolute and relative measures of performance on several agronomic variables.</li> </ul> <p>The first two columns (&quot;genotype_1&quot; &amp; &quot;genotype_2&quot;) are the identity of the two genotypes in the plot, which are identical in single-variety plots. The third column (&quot;assoc&quot;) refers to the plot type: single-variety (&quot;M&quot;) or mixed-variety (&quot;P&quot;) plot. Then, all absolute and relative measures of agronomic performance are reported as &quot;RAW_performance_variable_name&quot; and &quot;RYT_performance_variable_name&quot;, respectively. For single-variety plots, only absolute performances are reported. Reported performance variable are &quot;GY&quot; (Grain yield, g/m&sup2;), &quot;GNb&quot; (Grain number per m&sup2;), &quot;SY&quot; (Spike yield, g/m&sup2;), &quot;SNb&quot; (Spike number per m&sup2;), &quot;BY&quot; (Biomass yield, g/m&sup2;), &quot;PY&quot; (Protein yield, g/m&sup2;), &quot;TKW&quot; (Thousand kernel weight, g), &quot;SeY&quot; (Semolina yield, %), &quot;GPC&quot; (Grain protein content, %), &quot;TW&quot; (Test weight, kg/hL), &quot;RLVA&quot; (Rate of loss of vitreous aspect, %), &quot;YI&quot; (Yellowness index), &quot;GPD&quot; (Grain protein deviation, %).</p> <p>One R code file is available:</p> <ul> <li>&quot;Mu_FD_Mu_CY_Analysis.R&quot; contains all statistical analysis performed to produce the results presented in the main text and in the Supplementary Information of the study. It uses &quot;CWM_D.csv&quot; and &quot;RAW_RYT.csv&quot; files as inputs.</li> </ul>
