The plant growth regulating activity of (2-chlorophenyl) (5-(2-hydroxyphenyl)-3-(pyridin-3-yl)- 1H-pyrazol-4-yl) methanone and its binary complexes of Fe (III) and Cu (II) on Trigonella foenum-graecum (Methi) have been studied at pH 4.5 and 9.0 in order to make suggestions whether this ligand and its binary complexes of can be used as plant growth regulators. The plant growth was decided by measurement of parameters like percentage of germination, survival, seedling height, soot length, root length, root/soot ratio and width of young leaf. The average values of these parameters have been used to make a conclusion about plant growth regulating activity of ligand and its complexes.
