Job Demands, Resources, Occupational Burnout, And Individual Work Performance Among Commune-Level Civil Servants: Evidence from Gia Lai, Vietnam

/0 Comments/in /by

The operation of Vietnam’s two-tier local government system, comprising the provincial and commune levels, has heightened the requirements placed upon commune-level civil servants in relation to initiative, coordination, digital casework, and accountability for outputs. This study examines the associations among personal resources, the work environment, job demands, new-task demands, occupational burnout, and individual work performance. Data were collected in 2026 from 563 non-managerial professional civil servants working at commune level in Gia Lai Province. The scales were assessed using Cronbach’s alpha, exploratory factor analysis, confirmatory factor analysis, and covariance-based structural equation modelling in SPSS and AMOS; indirect effects were evaluated using 5,000 bootstrap resamples. The model demonstrated a good fit to the data (χ²/df=1.280; CFI=0.978; TLI=0.976; RMSEA=0.022; SRMR=0.034) and explained 42.6% of the variance in occupational burnout and 59.3% of the variance in individual work performance. Job demands and new-task demands were positively associated with burnout, whereas burnout was negatively associated with work performance. Implementation competence exhibited the strongest direct association with performance, followed by digital adaptability and public service motivation. Although the work environment did not demonstrate a sufficiently robust direct association with performance, it contributed to lower burnout. Both indirect paths, JD→BO→IWP and DQ→BO→IWP, were statistically significant. The findings indicate that strengthening administrative performance at commune level requires an integrated approach combining competence development, work design, digital support, and the prevention of sustained occupational depletion.

Factors Regulating Symbiotic Nitrogen Fixation Efficiency in Legume Crops: Mechanisms, Environmental Constraints, and Future Perspectives

/0 Comments/in /by

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.

Organic vs. Inorganic Fertilizers: A Review on Sustainable Mung Bean Production under Kabul Semi‑Arid Conditions

/0 Comments/in /by

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.

Flax (Linum usitatissimum L.) is an important oilseed and fiber crop with significant economic value. Efficient irrigation management is essential for improving crop productivity under the semi-arid conditions of Kabul, where water resources are limited. However, information on the optimum irrigation interval for flax production in this region is scarce.

This field experiment was conducted at the Agricultural Research Farm of the Faculty of Agriculture, Kabul University, during the spring season of 2025.The objective of this study was to evaluate the effect of different irrigation intervals (4, 8, 12, 16, and 20 days) on the growth and yield of flax, Badakhshee variety. The experiment was arranged in a Randomized Complete Block Design (RCBD) with five treatments and three replications across two sites.

Data were recorded on plant height, number of branches per plant, number of pods per plant, number of grains per pod, 1000-grain weight (g) and total yield per hectare. The results showed that irrigation intervals significantly (P ≤ 0.05) affected all measured parameters. The highest plant height (68.67 cm), number of pods per plant (189), and grain yield (1856.67Kg ha⁻¹) were obtained under the 12-day irrigation interval, which increased yield by approximately (27.87%) compared to the 20-day interval. In contrast, the lowest values for most traits were recorded under the 20-day irrigation interval.

These findings indicate that irrigation every 12 days provides optimal moisture conditions for flax growth under Kabul agro-climatic conditions. Therefore, this interval is recommended for maximizing yield while ensuring efficient water use.

Soybean Growth and Yield Response to Fertilizers: A Comparative Review of Organic and Inorganic Inputs under Kabul Semi‑Arid Conditions

/0 Comments/in /by

Soybean (Glycine max L.) is a globally important crop valued for its high protein and oil content, yet its productivity in Afghanistan remains constrained by poor soil fertility and reliance on chemical fertilizers. This review article synthesizes experimental evidence on the comparative effects of organic inputs (night soil, farm manure) and inorganic fertilizers (diammonium phosphate, urea) on soybean growth and yield under Kabul’s semi‑arid conditions. The purpose of this study is to evaluate sustainable nutrient management strategies that enhance crop productivity while maintaining soil health.

Field trials conducted at Kabul University employed a randomized complete block design with five treatments: control, night soil, farm manure, DAP, and urea. Growth parameters such as plant height, branches per plant, leaf number, and pods per plant were measured alongside yield attributes including 100‑seed weight and grain yield. Results demonstrated that organic amendments significantly improved soybean performance compared to chemical fertilizers. Farm manure produced the tallest plants, highest branching, and maximum pods per plant, with grain yield reaching 1725 kg/ha. Night soil accelerated flowering and pod formation while also improving yield (1616 kg/ha). In contrast, urea resulted in the lowest yield (1262 kg/ha), highlighting the limitations of sole reliance on chemical inputs.

The findings confirm that organic fertilizers enhance soil structure, microbial activity, and long‑term fertility, making them vital for sustainable soybean production in semi‑arid Kabul. Integrating organic inputs into nutrient management strategies can reduce dependence on chemical fertilizers, improve food security, and support climate‑resilient agriculture in Afghanistan.

The Effects of Behaviour-Based and Cognition-Based Interventions on Work-Life Balance Outcomes among Workforce in Indonesia

/0 Comments/in /by

Work-life balance has become increasingly important within the changing employment environment. However, evidence on how employees actively regulate the boundary between their professional and personal roles continues to be shaped largely by studies from Global North and office-based settings. This study investigates the influence of behaviour-based and cognition-based personal interventions on the three dimensions of work-life balance outcomes: work-related, nonwork-related, and stress-related. Adopting a quantitative, cross-sectional, and explanatory approach, data were gathered through a self-administered online survey from 427 employees representing various industries across Indonesia. Multiple linear regression models were then estimated, corresponding to each outcome dimension. The results showed that all models were statistically significant and that both intervention types were statistically significant to predict the three outcome domains. Behaviour-based interventions produce the strongest effect, particularly for work-related outcomes (β = 0.635) and stress-related outcomes (β = 0.625). Cognition-based intervention also contributes significantly, with their largest effect found for nonwork-related outcomes (β = 0.340). The work-related outcomes model has the strongest explanatory power with an adjusted R2 of 0.809. Overall, the findings indicate that behavioural and cognitive interventions operate as complementary mechanisms and broaden the relevance of previous studies’ findings of personal-intervention framework in the wider multisector workforce in Indonesia.

Review of Organic and Inorganic Fertilizer Practices in Mung Bean (Vigna radiata L.) under Kabul Climatic Conditions

/0 Comments/in /by

Mung bean (Vigna radiata L.) is a short-duration pulse crop of global importance, valued for its nutritional quality, nitrogen-fixing ability, and adaptability to semi-arid climates. In Afghanistan, particularly under Kabul agro-climatic conditions, productivity remains below global averages due to poor soil fertility, limited access to improved varieties, and inadequate nutrient management. This review synthesizes recent evidence (2022–2026) on organic and inorganic fertilizer practices in mung bean cultivation. Organic amendments such as poultry manure at higher application rates (8–10 t ha⁻¹) significantly enhance vegetative growth, pod formation, and grain yield [1,2,4]. Inorganic NPK fertilizers provide immediate nutrient availability but risk long-term soil degradation if applied alone [3,6]. Integrated nutrient management (INM), combining mineral fertilizers with organic inputs, improves soil fertility, microbial activity, and sustainability, offering superior productivity outcomes [7,11,12]. Improved varieties such as Enam demonstrate positive responses under INM strategies, underscoring the importance of genotype × environment × management interactions [2,5,9]. Recent studies highlight biofertilizers and micronutrient supplementation as promising approaches to further enhance nodulation, nitrogen fixation, and seed quality [3,8,10]. Key research gaps remain in varietal performance, soil fertility constraints, and region-specific INM practices. Adoption of integrated fertilizer management can substantially improve mung bean productivity and soil health in Kabul and similar semi-arid regions, contributing to food security and sustainable agriculture.

Mung bean (Vigna radiata L.) is an important pulse crop with considerable potential to enhance food and nutritional security, improve soil fertility, and increase farmers’ incomes in Afghanistan. However, its productivity remains constrained by the widespread use of low-yielding varieties and the challenges associated with semi-arid climatic conditions. This study evaluated the Agronomic performance and yield potential of four mung bean varieties under the Agro climatic conditions of Kabul, Afghanistan, where low annual precipitation, high summer temperatures, and climatic variability limit crop production. The experiment was conducted using a Randomized Complete Block Design (RCBD) consisting of four treatments: Helmandi (T1), Local (T2), 08 Certified (T3), and 07 Certified (T4), with six replications. Data were analysed using analysis of variance (ANOVA), and treatment means were compared using an appropriate mean separation test.

The results demonstrated significant differences (P < 0.05) among the evaluated varieties. The 07 Certified variety (T4) produced the highest mean grain yield (1,833.77 kg ha⁻¹), followed by 08 Certified (T3) (1,720.72 kg ha⁻¹), Local (T2) (1,378.87 kg ha⁻¹), and Helmandi (T1) (643.56 kg ha⁻¹). Mean comparison analysis confirmed significant differences among all varieties, with the performance ranking as T4 > T3 > T2 > T1. The superior yield performance of the 07 Certified variety indicates its greater adaptability and productivity under the semi-arid conditions of Kabul. These findings highlight the importance of promoting improved certified mung bean varieties to enhance crop productivity, support climate resilient agricultural systems, and contribute to improved food security and rural livelihoods in Afghanistan. Further multi location and multi-season evaluations are recommended to assess the stability, adaptability, and potential for wider adoption of the 07 certified variety.

Effect of Different Levels of Urea on Growth, Yield, and Yield Attributes of Mustard under Kabul Agro-Climatic Conditions

/0 Comments/in /by

Nitrogen is a key macronutrient that plays an essential role in plant growth, development, and yield formation in oilseed crops such as mustard (Brassica juncea L.). Proper nitrogen management is important for improving productivity while ensuring economic efficiency and environmental sustainability, particularly in low-input farming systems like those in Afghanistan. This study was conducted to assess the effect of different urea (nitrogen) levels on the growth, yield attributes, phenology, and grain yield of mustard under Kabul agro-climatic conditions. A field experiment was arranged with four treatments: T₁ (0 kg urea ha⁻¹), T₂ (60 kg urea ha⁻¹), T₃ (80 kg urea ha⁻¹), and T₄ (100 kg urea ha⁻¹) using a randomized design. Data were collected on plant height, number of branches per plant, number of pods per plant, phenological traits (flowering and maturity), and grain yield. The results showed that nitrogen application significantly improved vegetative growth and yield components of mustard. Increasing nitrogen levels enhanced plant height, number of branches, and pods per plant. Grain yield responded positively to nitrogen application, with the highest yield consistently obtained at 80 kg urea ha⁻¹. However, further increase in nitrogen above this level did not result in proportional yield improvement, indicating diminishing returns. Phenological traits such as days to flowering and maturity were not significantly affected by nitrogen levels. Overall, the study concludes that moderate nitrogen application optimizes growth and yield of mustard without affecting its growth duration. The application of 80 kg urea ha⁻¹ is recommended as the optimal rate for mustard production under Kabul conditions, as it improves productivity, enhances nitrogen use efficiency, reduces production costs, and supports sustainable agriculture.

/0 Comments/in /by

Chickpea (Cicer arietinum L.) is a vital pulse crop in semi-arid regions, yet its productivity is often constrained by poor agronomic practices, particularly seed rate management (Bhatt et al., 2022; Rahimi et al., 2024). A field experiment was conducted in Kabul, Afghanistan, to evaluate the effect of five seed rates (65, 75, 85, 95, and 105 kg/ha) on growth and yield performance under semi-arid conditions. The trial was laid out in a Randomized Complete Block Design (RCBD) with three replications. Results demonstrated significant differences (p ≤ 0.05) among treatments for plant height, leaf area, pods per plant, seeds per pod, 100 seed weight, and yield, while the number of branches per plant showed no significant variation. The optimum seed rate was identified as 85 kg/ha, which produced taller plants (33.2 cm), higher pod numbers (25–32 pods/plant), heavier seeds (31 g per 100 seeds), and improved yield (0.465 kg/m²). Excessive seed rates (105 kg/ha) reduced yield due to overcrowding, intra specific competition, and depletion of limited soil moisture, resulting in smaller seeds (25 g per 100 seeds) and fewer pods (20.7 pods/plant). These findings highlight the critical role of optimized seed rate management in enhancing chickpea productivity under Kabul’s challenging climatic conditions, where short growing seasons, spring frost, and terminal drought are major constraints (Jettner et al., 2019; Siddique et al., 2022). The study provides evidence based recommendations for local farmers to replace traditional broadcast sowing with optimized seed rates, thereby improving food security and income generation in Afghanistan (FAO, 2026; Merga & Haji, 2019).
