Today's agriculture faces many concerns in maintaining crop yield while adapting to climate change and transitioning more sustainable cultivation practices. The application of plant biostimulants (PBs) is one the methods that step forward address these challenges. advantages PBs have been reported numerous times. Yet, there a general lack quantitative assessment overall impact on production. Here we report comprehensive meta-analysis (focus non-microbial PBs) over thousand pairs open-field data total 180 qualified studies worldwide. Yield gains upon biostimulant were compared across different parameters: category, method, species, condition, soil property. results showed (1) add-on benefit among all categories average 17.9% reached highest potential via treatment; (2) applied arid climates vegetable had yield; (3) efficient low organic matter content, non-neutral, saline, nutrient-insufficient, sandy soils. This systematic review provides guidelines gives consultants growers insights into achieving an optimal from application.

Climate change is a critical yield–limiting factor that has threatened the entire global crop production system in present scenario. The use of biostimulants agriculture shown tremendous potential combating climate change–induced stresses such as drought, salinity, temperature stress, etc. Biostimulants are organic compounds, microbes, or amalgamation both could regulate plant growth behavior through molecular alteration and physiological, biochemical, anatomical modulations. Their nature diverse due to varying composition bioactive they function various modes action. To generate successful biostimulatory action on crops under different parameters, multi– omics approach would be beneficial identify predict its outcome comprehensively. ‘ omics’ greatly helped us understand mode plants at cellular levels. acting messenger signal transduction resembling phytohormones other chemical compounds their cross–talk abiotic help design future management changing climate, thus, sustaining food security with finite natural resources. This review article elucidates strategic prospects mitigating adverse impacts harsh environmental conditions plants.

Organic biostimulators support wheat growth in unfavorable conditions; however, to date, multifactorial assessments of their role the plant–pesticide–pathogen system have been poorly investigated. The goal this study was evaluate changes metabolite profile (protein, carbohydrate, phenolic compounds, acid phosphatases, and amino acids) antioxidant potential (antioxidant enzymes) that is infested with F. culmorum exposed humic acids, nitrophenols, six pesticides. Additionally, concentration mycotoxins grain dissipation time pesticides plants were determined. In experiment, we explored differentiated activities acids nitrophenols metabolism during fungal pathogenesis pesticide protection. Nitrophenols decreased oxidative stress through induced catalase activity. contrast, contributed highest enhancement total level carbohydrates (27%) inoculated wheat. Both reduced mycotoxin (DON, 3-AcDON, 15-AcDON, NIV) by 32% increased (13%). Unexpectedly, shortened degradation (DT50) spiroxamine up 60% overall results provide novel information on metabolites, defense, pesticide–biostimulator–pathogen system.
