摘　　要：Globally,salinity is a brutal environmental constraint that poses a major threat to agriculture worldwide,causing nutrient imbalances and oxidative stress,leading to reduced crop yields and quality.Date palm waste from the agro-industry is a major environmental problem,but its conversion to biochar for soil amendment could help alleviate the effects of salinity stress.Pepper is a commonly grown horticultural crop that is sensitive to salinity.That’s why the current experiment was conducted with the novel idea of exploring the potential use of biochar-based fertilizer derived from date palm waste as a mitigation strategy for salinity-related problems in pepper.The study was conducted as a pot experiment in a growth chamber under controlled conditions.The experiment con-sisted of four treatment groups:Control(no salinity stress);BM350E(biochar application only);NaCl(salinity stress without biochar application);BM350E+NaCl(combined biochar and salinity stress application).The soil was amended with biochar at a concentration of 3 g kg^(-1) soil and pepper seedlings were exposed to salinity stress with 150 mM NaCl for seven days.The morphological,biochemical,and physiological responses were then eval-uated.The use of BM350E biochar significantly improved plant growth under saline conditions,increasing shoot fresh weight by 9.41%,root fresh weight by 15.32%,shoot length by 5.22%,and root length by 12.57%.It also increased chlorophyll a(Chl.a)by 8.28%,chlorophyll b(Chl.b)by 80.20%,and carotenoids(Car)by 52.43%while increasing antioxidant enzyme activities.In conclusion,BM350E biochar has the potential to effectively mitigate the negative effects of salinity on pepper growth.
