Purpose: The development of plant biostimulants from fish industry waste will increase crop yields and reduce environmental pollution. The aim of our study was to develop an optimal method for the production of fish hydrolysates and to test their effectiveness as plant biostimulants for important crops such as corn and beans.
Method: Three different hydrolysates were used: I - from guts only, II and III - from guts and heads. I and III were hydrolyzed using fish guts own enzymes, while II was additionally stimulated with nitric acid.
Results: It was found that for beans, the treatment with a low concentration of fish hydrolysates (1%) was more optimal, while for corn, higher concentrations of hydrolysates (2% and 5%) were more effective. Treatment with all hydrolysates reduced the chlorophyll a content in maize leaves. For plants, hydrolysates from fish guts alone were more effective as biostimulants, especially for legumes that formed a root-nodule symbiosis.
Conclusion: According to all the studied indicators, hydrolysate I (only from viscera) at a concentration of 1% was the most effective in the treatment of beans and corn, increasing the index of seedling vigour, growth and total vegetative mass.
Research Highlights
• Use of fish waste hydrolysates can increase crop and reduce environmental pollution
• Beans require lower concentrations of fish waste hydrolysates than corn.
• Hydrolysate from only fish viscera acts better as a biostimulant.
• Hydrolysate with heads has fewer enzymes and fewer low-molecular-weight peptides.
• Hydrolysate with heads has a lot of calcium, which negatively affect
