Az-Azahra, et al (2024) Effectiveness 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 application on the growth of red chili plants during the vegetative stage under waterlogging. Journal of Suboptimal Lands. https://doi.org/10.36706/jlso.13.2.2024.686

Riparian wetlands hold great potential for agricultural cultivation but present challenges, particularly during waterlogged conditions that often occur during the rainy season. A recent study explored the effectiveness of biochar in supporting the growth of red chili plants (Capsicum annuum L.) under such conditions.

The study tested different treatments using rice husk and coconut shell biochar, comparing them to a control without biochar. Waterlogging can cause serious stress to plants, leading to reduced shoot and root growth, fewer leaves, and decreased dry weight. However, biochar is known for its ability to improve soil structure and nutrient retention.

Results showed that while waterlogging had a negative impact on plant growth overall, biochar treatments—particularly with rice husk biochar—led to significant improvements in root length, leaf area, and overall plant resilience compared to the control group. However, in waterlogged conditions, plants treated without biochar surprisingly demonstrated better growth than those treated with biochar.

The findings suggest that while biochar can enhance growth under normal conditions, its benefits under prolonged waterlogging may be limited or complex. Rice husk biochar showed the most promise for improving plant recovery after waterlogging, likely due to its ability to improve soil aeration and nutrient absorption.

These results emphasize the need for further research into biochar’s role in different environmental conditions and its potential to support sustainable agriculture in challenging environments.
