Use of 6-oxo-1,4,5,6-tetrahydropyridizin-3-carboxylic acid, 1-methyl 6-oxo-1,4,5,6-tetrahydropyridizin-3-carboxylic acid and 1-aklyl-6-oxo-1,4,5,6-tetrahydropyridazine-3-carboxylic acid for improving growth performance in plants

A method for improving plant performance, comprising:

• contacting a plant with a compound including at least one of 6-oxo-1,4,5,6-tetrahydropyridizin-3-carboxylic acid or 6-oxo-1,4,5,6-tetrahydropyridizin-3-carboxylic salt to enable an increase in performance of the plant over that of untreated plants by increasing at least one of:
• weight and biomass of the foliar parts the plant over that for wild type plants;
• weight or biomass of the roots of the plant over that for wild type plants;
• seedling emergence of the plant over that for wild type plants;
• yield of the plant over that for wild type plants;
• agronomic performance of monocotyledonous and dicotyledonous plants over that for wild type plants;
• drought resistance over that for wild type plants;
• drought recovery over that for wild type plants;
• germination and seedling emergence rate of plants in cool and warm germination temperatures over that for wild type plants;
• root nodulation with a nitrogen fixing bacterium.
