Described is the use, [in the absence of (a) fertilizers and (b) Periodic Table Group IIa and greater Group metal cations and chelated metals], of aqueous solutions of the N-substituted aspartic acids, (i) N-(1,2-dicarboxyethyl)aspartic acid [`IDS'] and (ii) N,N'-1,2-ethanediylbis-aspartic acid [`ED

Described is the use, [in the absence of (a) fertilizers and (b) Periodic Table Group IIa and greater Group metal cations and chelated metals], of aqueous solutions of the N-substituted aspartic acids, (i) N-(1,2-dicarboxyethyl)aspartic acid [`IDS'] and (ii) N,N'-1,2-ethanediylbis-aspartic acid [`EDDS'], ammonium salts, alkali metal salts, ammonium-alkali metal salts and optical isomers thereof in stimulating or regulating the growth of a living, growing plant precursor [germinating seed] or plant [from the `seedling stage' to the `late-maturity stage']. Such use, optionally, is in the presence of aditional adjuvants free from fertilizer as well as Periodic Table Group IIa and greater metal Group cations and chelated metals. Also described are novel compositions comprising (a) the `IDS' and/or ammonium, alkali metal, ammonium-alkali metal salts thereof as well as optical isomers thereof in admixture with (b) the `EDDS' and/or ammonium, alkali metal and ammonium-alkali metal salts thereof as well as optical isomers thereof.
