OPTIMIZING MUNGBEAN YIELD AND NUTRITIONAL QUALITY: THE SYNERGISTIC IMPACT OF ZINC-ENRICHED SOIL APPLICATION AND AMINO ACID FOLIAR BOOST

Abstract

Zinc is crucial for chlorophyll production, and soil variables affect its availability for plants by regulating its sorption and desorption, thereby affecting its content. Amino acids are crucial proteins in plants for development, growth, and overall functioning, acting as stress-response molecules that initiate the production and accumulation of certain amino acids in response to environmental stresses. The study was designed in CRD-factorial to check the solo and combined application of amino acids (0 ppm, 250 ppm, and 500 ppm) and zinc (0 ppm, 10 ppm, and 15 ppm) on biochemical, growth, and yield attributes of mung bean. The results showed that total amino acids and phenolics were increased in dose (amino acids 250 + zinc 10) compared to control. In addition, crop growth rate (CGR) was increased in dose (amino acids 500 + zinc 10) over control. The 100-seed weight was also increased in dose (amino acids 250 + zinc 10) compared to control. The crop growth and yield rate decreased by increasing the amino acids and zinc doses. It is suggested to apply the dose (amino acids 250 + zinc 10) for better growth and yield production of mung bean.
