Saline soil poses a significant challenge to agricultural productivity, particularly in coastal regions. A study conducted at Noakhali Science and Technology University investigated the potential of biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More to improve the growth and yield of okra under saline conditions. Biochar was applied in three doses, and the results indicated significant improvements in various growth and yield parameters of okra.

The study found that higher biochar doses resulted in increased plant height, number of leaves, lamina length, and petiole length. Additionally, biochar-treated plants exhibited earlier flowering and higher chlorophyll content, indicating enhanced photosynthetic efficiency and stress tolerance. The application of biochar also positively influenced okra fruit characteristics, including increased fruit length, diameter, and weight. The number of fruits per plant and overall yield were notably higher in biochar-treated plants, with the 4 tons/ha treatment proving the most effective.

Biochar improves soil properties by enhancing nutrient availability, improving soil structure, and increasing water-holding capacity. These benefits help mitigate the adverse effects of salinity stress on okra plants, leading to better growth and higher yields. The study’s findings suggest that biochar could be a sustainable solution for farmers in coastal regions facing soil salinity issues, potentially leading to improved crop performance and food security. Further research is needed to integrate biochar application into agricultural practices for wider adoption and to fully realize its benefits in saline-affected areas.
