Abstract

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 consisted 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 evaluated. 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.
