Data on Phaseolus vulgaris L. waste were reported by Pineda-Insuasti et al. (2014) and Fialho et al. (2019) and will be labeled “Waste 1” and “Waste 2,” respectively, in further discussion. Waste 1 refers to “harvest wastes, the entire plant” (Pineda-Insuasti et al., 2014). Waste 2 refers to “Straw bean: the residue of production of the bean” (Fialho et al., 2019). Similarly, data for Zea mays L. cobs from Latshaw and Miller (1924) and Titiloye et al. (2013) will be labeled “Cobs 1” and “Cobs 2,” respectively. The row “Zea mays L.—average” denotes average composition of the entire plant, based on organ weights reported by Latshaw and Miller (1924).
