Abstract:
Climate change, resource depletion, and biodiversity loss are all threatening our agriculture. A new agricultural revolution is required to improve crop yield while also ensuring food quality and safety in a sustainable manner. Seed priming with yeast and chitosan can help to ensure agriculture's long-term viability. Seed elicitor priming is a powerful technique that alters seed metabolism and signalling pathways, affecting not just germination and seedling establishment, but also the entire plant life cycle. Improved plant growth and development, higher productivity, and improved food nutritional quality are just a few of the benefits. Elicitor -priming affects biochemical pathways as well as the balance of reactive oxygen species and plant growth hormones, promoting stress and disease resistance while reducing pesticide and fertiliser use. The germination percentage, shoot height, and shoot weight were all used to assess seed vigour. The addition of yeast and chitosan as an elicitor had a modest positive effect on seed vigour, implying that pre-sowing treatments can have positive or negative effects on seed vigour depending on the dosage of treatments. More research is needed to establish their effects and the best seed priming dosage.
