Abstract: 6-oxo-1,4,5,6 tetrahydropyridazine-3-carboxylic acid or its salts or 1-methyl 6-oxo-1,4,5,6-tetrahydropyridizin-3-carboxylic acid or its salts, to plants can cause an increase in parameters such as germination, seedling emergence, growth, drought tolerance and recovery, yield, rhizobia induced root nodulation as compared to untreated wild type plants. 1-Methyl 6-oxo-1,4,5,6 tetrahydropyridazine-3-carboxylic acid or its salts is chemically the simplest 1-alkyl 6-oxo-1,4,5,6-tetrahydropyridazine-3-carboxylic acid and as such is an example showing the effectiveness of a 1-alkyl 6-oxo-1,4,5,6 tetrahydropyridazine-3-carboxylic acid. Higher series derivatives such as 1-alkyl 6-oxo-1,4,5,6 tetrahydropyridazine-3-carboxylic acids also induce beneficial effects on treated plants.
