The Effect of Polyglutamic Acid Produced from Glutamic Acid Wastewater on Maize Growth

This experiment uses polyglutamic acid water-soluble fertilizer produced from glutamic acid fermentation waste liquid as the experimental fertilizer to study its impact on maize yield and quality in maize cultivation. The results showed that compared to farmers who are accustomed to fertilization, the application of the new water-soluble polyglutamic acid fertilizer reduced the bald head length of corn by 0.7 cm; The weight of 100 grains of corn increased by 0.7g, resulting in an increase of 26.7 kilograms of corn per mu, with a yield increase of 5%.
