ABSTRACT Introduction Previous studies showed that biochar amended soils significantly enhanced the growth and yield of quinoa under water limitations. So it becomes an emerging agronomic strategy to consider for sustainable production. Biochar can specifically be considered area particularly receiving low annual rainfall more vulnerable current climate change conditions. Materials Methods A field experiment was conducted using variety INIA 415 Pasankalla, employing a factorial design assess effects different application rates made municipal pruning waste agricultural (0, 1, 2, 3 t·ha⁻¹), three irrigation intervals (irrigation every 5 days, 10 15 days). The volumetric soil moisture content, hydraulic properties, quinoa's biometric characteristics components were evaluated.

Chenopodium quinoa Willd. (quinoa), a highly nutritious pseudocereal, is promising crop to address global food insecurity challenges intensified by population growth and climate change. However, drought stress remains significant constraint for cultivation. The plant exhibits several morphophysiological adaptations water conditions, including root system modifications, reduced rate, leaf abscission, stomatal closure. While these enhance tolerance, they can also negatively impact growth, potentially through alterations in architecture, physiological changes, e.g., regulations, anatomical changes. Different studies have suggested that soil amendment with biochar, pyrolyzed organic material, improve productivity under conditions. Biochar application the significantly enhances physiochemical characteristics maintains status, thereby promoting mitigating negative consequences of on production. This review focuses current understanding behavior potential biochar as management strategy. We summarize existing research applying biochar-amended alleviate stress.

Globally, Hibiscus sabdariffa L. (Malvaceae), commonly known as roselle or hibiscus, is a multipurpose vegetable crop. In Malawi, where it referred to ‘Chidede’ (Chichewa), recognized an underutilized traditional plant with significant potential. Traditional production in Malawi being promoted enhance nutritional food security and climate change mitigation. Recently, biochar has become increasingly used improve agricultural productivity through climate-smart technologies. To date, the influence of rice husk (RHB) on H. remains underexplored. This study aims evaluate effects RHB vegetative growth, response water stress, post-stress recovery using greenhouse pot experiment. Our findings indicate that biochar-amended soil enhanced height, stem thickness, total leaf area by 16.5%, 12.0%, 12.9%, respectively. Water stress significantly reduced all assessed growth parameters (p < 0.05) except average per plant. Under conditions, biochar-treated plants were taller had higher specific 0.05), demonstrating positive effect. A analysis revealed fully recovered height biomass, while partial was observed for root collar diameter compensatory area. Biochar-treated exhibited superior compared those grown unamended soil. Overall, larger diameter, fresh greater These underscore biochar’s potential sustainable amendment enhancing resilience crops. Further studies should explore field experiments access environmental heterogeneity examine diverse factors influencing efficiency.
