Abstract: | A precursor in tetrapyrrole biosynthesis, 5-aminolevulinic acid (ALA), was applied via presowing soaking in Vigna catjung,
V. mungo, and V. radiata. ALA increased plant growth and influenced dry matter accumulation in leaves, stems, and pods through
increased chlorophyll content and photosynthetic CO2 absorption. At harvest, ALA treated plants had increased number of pods per plant, seeds per pod, 100 seed dry matter, biological
yield, and the harvest index. Therefore, pretreatment of seeds with optimal concentration of ALA is recommended for improving
the growth and productivity of tropical legumes.
