This study was conducted from May–September 2025 / the 2025 growing season at the Research Farm of the Department of Agronomy, Faculty of Agriculture, Kabul University, to evaluate the effects of organic and inorganic fertilizers on the growth, yield, and yield components of mung bean (Vigna radiata L.) variety 08 Zudrus. The experiment was arranged in a randomized complete block design (RCBD) with four treatments with three replications. Treatments included a control, NPK fertilizer, XiR Biomass containing 10% humic acid, and XiR Biomass containing 20% humic acid. Data on growth, yield components, and yield parameters were analyzed using STAR software (version 2.0.1) through analysis of variance (ANOVA) at the 5% significance level. Fertilizer treatments significantly influenced several growth and yield traits. XiR Biomass containing 20% humic acid produced the tallest plants (35.10 cm), the highest number of pods per plant (10.53), and the greatest biological yield (7851.63 kg ha⁻¹), whereas XiR Biomass containing 10% humic acid produced the highest grain yield (2202.38 kg ha⁻¹) and number of grains per pod (11.00). In contrast, tiller number, branch number, pod length, pod width, and 100-seed weight were not significantly affected. Overall, XiR Biomass organic fertilizers showed greater potential than NPK fertilizer for improving mung bean growth and productivity under the agro-ecological conditions of Kabul.

Mung bean (Vigna radiata L.) is a short‑duration legume of high nutritional and agronomic importance, particularly suited to semi‑arid regions such as Kabul, Afghanistan. Despite its potential, mung bean productivity in Afghanistan remains below global averages, constrained by poor soil fertility, limited varietal development, and inadequate crop management practices. This review synthesizes Kabul University research and global literature, focusing on the comparative impacts of organic and inorganic fertilizer practices on mung bean yield attributes. Organic fertilizers such as farmyard manure, compost, and humic‑acid enriched biomass enhance soil structure, microbial activity, and long‑term fertility, whereas inorganic fertilizers supply rapid nutrient availability but risk soil degradation if used exclusively. Evidence from Kabul trials demonstrated that humic‑acid enriched organic fertilizer (OF2) produced superior plant height, grain number per pod, seed yield, and biological yield compared to NPK and control treatments, underscoring its relevance for semi‑arid Kabul conditions. Integrated nutrient management (INM), combining organic and inorganic inputs, offers synergistic benefits by balancing productivity with sustainability. However, adoption in Afghanistan is constrained by economic limitations, weak extension services, and limited varietal testing. This review concludes that INM represents the most sustainable pathway for mung bean cultivation in Kabul’s semi‑arid environment, while highlighting research gaps in varietal response, soil fertility restoration, and farmer adoption strategies.

The sustainable management of soil fertility is essential for improving common bean (Phaseolus vulgaris L.) productivity under the semi-arid conditions of Afghanistan. This study evaluated the comparative effects of two organic fertilizers, inorganic fertilizer (NPK), and their integrated application on the growth and yield performance of common bean during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University. The experiment was arranged in a Randomized Complete Block Design (RCBD) with six fertilizer treatments and three replications. Growth traits, yield components, grain yield, biological yield, and harvest index were analyzed using analysis of variance (ANOVA), and treatment means were separated by Tukey’s HSD test at the 5% probability level. Fertilizer treatments significantly influenced most growth and yield parameters. The integrated application of 50% OF-1 + 50% NPK (T5) consistently produced superior plant growth, increased yield components, and achieved the highest grain yield, biological yield, and harvest index compared with the sole application of organic or inorganic fertilizers and the unfertilized control. The improved performance of the integrated treatment was attributed to enhanced nutrient availability and more efficient nutrient utilization throughout the crop growth period. These findings demonstrate that integrated nutrient management is a sustainable and effective strategy for increasing common bean productivity under semi-arid agroecological conditions. Future studies should evaluate long-term effects of integrated nutrient management under diverse agroecological conditions.

Symbiotic nitrogen fixation (SNF) is a fundamental biological process that enhances legume productivity while reducing dependence on synthetic nitrogen fertilizers. However, its efficiency varies considerably across production systems because it is regulated by complex interactions among plant genetics, rhizobial compatibility, physiological processes, environmental conditions, and agronomic management. This review synthesizes current knowledge on the mechanisms regulating SNF and critically examines the biological, environmental, and management factors that determine its effectiveness. The review integrates evidence from the literature on the molecular basis of legume–rhizobium symbiosis, physiological regulation of nitrogen fixation, the influence of soil properties, nutrient availability, climatic stresses, and agronomic practices, and evaluates emerging technologies and future research directions. The synthesis demonstrates that SNF performance is inherently context-dependent and cannot be optimized through a single intervention. Instead, successful nitrogen fixation requires coordinated management of host genotype, rhizobial inoculants, soil fertility, water availability, and crop management while accounting for local environmental conditions. The review also identifies important knowledge gaps, including limited long-term field validation, insufficient integration of multidisciplinary approaches, and challenges in translating emerging genomic, microbial, and precision agriculture technologies into practical farming systems. Overall, this review emphasizes that integrated, site-specific management combined with continued advances in biofertilizer development and multidisciplinary research is essential for maximizing SNF efficiency, reducing reliance on synthetic nitrogen fertilizers, and supporting sustainable, climate-resilient agricultural production.
