Balancing chemical fertiliser application for optimal maize yield and environmental safety
65-76Views:184Chemical fertilisers play a crucial role in enhancing maize productivity by supplying essential nutrients, particularly nitrogen, phosphorus, and potassium. However, excessive and imbalanced application of these fertilisers may result in soil degradation and environmental pollution. This review presents a comprehensive, bibliometric, and literature-based analysis of research on the balanced use of chemical fertilisers in maize production, spanning 2000 to 2025, and uses VOSviewer 1.6.20 as the analytical tool. The study analysed data from the Web of Science to examine publication trends, the configuration of keyword networks, and the dynamics of international research collaborations. The Mann-Kendall test revealed a significant positive trend (p = 0.001) in the volume of publications focused on chemical fertiliser balancing, with a coefficient of determination (R²) of 0.5153. A total of 549 relevant studies were identified globally, with no language restrictions applied, indicating sustained growth in research output over time. Field studies demonstrate that reducing chemical fertiliser use by up to 25% when combined with biological amendments can maintain or enhance yields across diverse agroecological conditions. The emphasis is placed on sustainable fertilisation practices that balance productivity and environmental safety, highlighting challenges and future directions for adoption. Balanced fertiliser management is crucial for sustainable maize production systems, which simultaneously contribute to food security and environmental conservation. This study is significant as it systematically maps the evolution and current state of research on balanced chemical fertiliser use in maize production, providing valuable insights into publication trends, collaborative networks, and practical agronomic outcomes. Despite the progress, there remains a significant gap in region-specific guidelines and long-term impact assessments of integrated fertiliser management practices, which future research should address to optimise sustainable maize production tailored to diverse agro-ecological zones.

Customer Relationship Systems and Business Models
99-106Views:279The object of this study is a comprehensive review of customer relationship management (CRM) systems applied increasingly in several fields of economy. The CRM is not merely a subsequent software technology and application in the field of Business Intelligence, but rather a novel, comprehensive customer-centric approach to an organization’s philosophy in dealing with its customer for the sake of realization of short- and long-range business target contrary to the traditionally widespread productcentric approach. The object of the study, following a short
synopsis of the theoretical and practical aspects of the CRM systems, is to analyse the range of the actual and potential users and to survey the CRM market. It will be analysed the scope of CRM supported business activities and processes, the terms and possible methods of launching and will be outlined a feasible model, too. The aim of conspectus of different CRM strategies (layers) is to reveal the urging need of turning approach in the field of management. -
Impact of precision irrigation on the unit income of maize production
157-162Views:401The study of the economic/economic impact of precision farming should be a priority area in digital agriculture, as the results, profitability, and efficiency indicators can have a significant decision-support effect on the development of both the agronomic and the technical regions of individual farms both in the longer and shorter term. Individual firms, companies, farmers, and family farms quantify the effectiveness of their farming processes. The modern age offers the possibility of digitally recording all the elements of farming technology, making it possible to analyse the cost-effectiveness of a farm more effectively and, in some cases, to carry out more detailed analyses. Nevertheless, the number of farms demonstrating their profitability with such precise economic calculations is still minimal.
Our analyses were conducted on a 56,02 ha field of Balogh Farm-Tépe Ltd. The agricultural operations carried out were fully documented so that the inputs (seeds, fertilisers, pesticides, crop enhancers) were recorded in coordinates and kind, as well as the specific yields, grain moisture data, irrigation norms, and irrigation rotations. At the same time, the company's owner provided the data's monetary value. The main econometric indicators (yield, production value, cost of production, income, cost price) related to the evaluation of the enterprise management were evaluated along with the spatial data in the irrigated and non-irrigated tables. Our calculations show that a given year's climatic and market characteristics fundamentally determine the cost and income relations of a plot of land (and thus of an entire farm). In addition to additional inputs, introducing some elements of precision farming and intensification and increasing yields improves yield security and allows for excellent yield stability.
