Plants encounter numerous biotic and abiotic challenges, with biotic stresses significantly limiting wheat productivity. Competition for nutrients and space among plants adds another layer of stress. Defense priming is a promising approach to enhancing plant protection against these environmental stresses. This study explores BABA (β-aminobutyric acid) priming in wheat againstBipolaris sorokinianaunder varying degrees of competition. We assessed growth parameters, disease phenotype, biochemical changes, and yield-related traits in both primed and non-primed wheat under disease pressure and competition. Our findings revealed that growth parameters declined in both primed and non-primed wheat as competition increased. However, primed wheat showed better morphological growth than non-primed wheat at each competition level. Under disease pressure, primed wheat demonstrated protection comparable to non-challenged plants at all competition levels, while non-primed plants were susceptible. Non-primed wheat under high-density (HD) conditions exhibited the highest disease susceptibility due to intense competition. BABA-primed plants showed better disease protection at each competition level compared to non-primed plants. BABA priming allowed plants to mitigate competition effects and maintain a consistent defense response. The yield performance of primed wheat was superior to that of non-primed wheat across all competition levels. Our research suggests BABA priming as an effective pesticide-free strategy for crop protection against pathogens under competitive conditions.
