Abstract

Continuous and excessive application of inorganic-N fertilizer leads to accumulation of chemical residues in soils, as plants typically utilize only about 50% of the applied nitrogen, which can further lead to environmental pollution. Resolve the low nitrogen uptake and fertilizer use efficiency, organic amendments, and beneficial microorganisms provide viable alternatives. The objective of this research was to evaluate the effects of different PGPR concentrations and cattle manure doses on nitrogen uptake dynamics and nitrogen use efficiency parameters (NUpE, NUtE, and NUE), as well as shallot growth and yield, to determine the most efficient treatment that supports nutrient efficiency and sustainable agronomic practices. The experiment used a constant nitrogen inorganic fertilizer of 100 kg ha-1. A factorial randomized block design was employed, consisting of four PGPR concentrations: 0, 10, 20, and 30 mL L-1. The second factor was cattle manure dosage consisted of 0, 10, and 30 ton ha-1. Observation variables included plant growth, yield components, nitrogen uptake dynamics, nitrogen uptake efficiency (NUpE), nitrogen utilization efficiency (NUtE), and nitrogen use efficiency (NUE). The results indicated significant interactions between PGPR and cattle manure in the number of tillers at 8 weeks after planting (WAP), crop growth rate (CGR) at 6–8 WAP, chlorophyll index, fresh and dry weight, and bulb weight. The treatment combining 30 mL L-1 PGPR with 30 t ha-1 cattle manure significantly increased average bulb weight by 136.6% compared to without PGPR + without cattle manure. This treatment also achieved the highest nitrogen uptake across all growth stages, peaking at 1 kg ha-1 per day at 56 DAP and recorded the highest NUpE from 41.90% to 64.50%, and reduced soil nitrogen losses by 22.6%. Consistent improvements in NUpE, NUtE, and NUE indicate that this integration enhances nitrogen translocation into shallot bulbs, leading to more efficient nutrient use, supporting higher productivity, and sustainable nutrient management.

Abstract

Digital financial management has become an important pillar of global economic progress, transforming the way individuals, businesses and countries manage finances. In developed countries, digital banking and payment systems are rapidly evolving, while in developing countries, the adoption of digital technologies continues to increase, as seen by the widespread access to fintech and mobile banking services. Since 2017, research on technology in financial management has shown an upward trend, with bibliometric analysis used to map trends, challenges and influencing factors across different countries. The early 2000s were a pivotal moment in the evolution of digital financial management, driven by the use of smartphones as the primary access to the internet. Research from 1706 to 2025 recorded exponential growth, especially since 2014. Researchers utilise platforms such as Google Scholar to disseminate information widely. Keywords such as “Fintech,” “big data,” and “digital finance” indicate further research opportunities. Fintech has revolutionised financial services with technologies such as blockchain and big data, increasing efficiency, transparency, and personalisation of services, and driving innovation in the global financial ecosystem.
