Effect of sowing date on height, crown diameter, biomass accumulation, seed biomass, and seed production (seed number), total biomass, and the slope of the transformed reproductive biomass—vegetative biomass relationship (R-V) of <i>Chenopodium glaucum</i> and <i>Amaranthus retroflexus</i>.

<p>Values are means with SE in parentheses. Different letters for the same attribute within a species indicate statistical difference among sowing date treatmetns at <i>P</i> < 0.05. Slope R-V is the slope of the regression of log transformed reproductive biomass on log transformed vegetative biomass. Intercept values were 0.139 and -0.312 and RMSE values were 0.111 and 0.117 for <i>C</i>. <i>glaucum</i> and <i>A</i>. <i>retroflexus</i>, respectively.</p><p>Effect of sowing date on height, crown diameter, biomass accumulation, seed biomass, and seed production (seed number), total biomass, and the slope of the transformed reproductive biomass—vegetative biomass relationship (R-V) of <i>Chenopodium glaucum</i> and <i>Amaranthus retroflexus</i>.
