Maize, regarded as a staple economic crop, attracts special global attention with the aim to enhance its production. Foliar fertilisation offers complementary method traditional soil amongst resource-limited agricultural systems, providing more efficient solution nutrient deficiencies, especially in suboptimal conditions. This study aimed analyse foliar fertiliser formulation research directions and their application maize A literature search was conducted Web of Science (WoS) database. Bibliometric analyses were performed using VOSviewer software (version 1.6.17). The changes publication trends documents tested Mann–Kendall test. production effects independently synthesised. results showed strong positive increase regarding (R2 = 0.7842). predominant nutrients that affected nitrogen, phosphorous, potassium, zinc, iron, manganese. timely corrected deficiencies and/or sustained supply under several abiotic stresses. at critical growth stages like flowering grain filling boosted carbohydrate protein content, lipid levels, kernel size, mineral weight grain. review identified important gaps, namely genotype-specific responses, interactions other agronomic practices, long-term environmental effects.

Polymer-coated controlled-release fertilizers’ (CRFs) unique nutrient release mechanism has the potential to mitigate leaching of mobile soil nutrients, such as nitrate-nitrogen (NO3-N). The study aimed evaluate capacity a polymer-coated CRFs maintain maize (Zea mays L.) crop growth/health indicators and production goals, while reducing NO3-N risks compared conventional (CONV) fertilizers in North Florida. Four CRF rates (168, 224, 280, 336 kg N ha−1) were assessed against no nitrogen (N) application current University Florida Institute for Food Agricultural Sciences (UF/IFAS) recommended CONV (269 fertilizer rate. All treatments, even lowest rate (168 ha−1), produced yields, leaf tissue concentrations, plant heights, aboveground biomasses (AGB), area index (LAI) significantly (p < 0.05) greater than or similar treatment. Additionally, 2022, treatment resulted increases late-season movement into highly leachable areas profile (60–120 cm), none treatments did. However, back-to-back rainfall (>76.2 mm over three days) events 2023 growing season masked any trends was likely completely flushed from system. results this two-year suggest that can achieve desirable growth, health, also having reduce NO3-N; however, more research is needed fully capture quantify through profile. Correlation Principal Component Analysis (PCA) revealed performance influenced by environmental factors temperature. In temperature-driven aligned with uptake, supporting higher yields minimizing movement. 2023, rainfall-driven variability led an increase benefits treatments. These analyses provided critical insights relationships between performance, emphasizing importance adaptive management under varying climatic conditions.

Climate change is forcing the search for innovative solutions to effectively reduce its harmful effects on food production. In addition, increasingly stringent regulations are being introduced in European Union (the Green Deal), mandating reductions mineral fertilizer doses, which can crop yields. One technology could be soil fertilization and foliar application of Si-based fertilizers. A two-year field experiment (2023 2024), commercial conditions Kraski (52°2′42″ N, 18°54′6″ E), Central Poland, studied effect differentiated products yield quality maize grain at two levels nitrogen/phosphorus/potassium (NPK) (100% 50%). The SiGS® (Si—200 g kg−1, Ca—181 Mg—46 Mn—45 kg−1) was applied doses 100, 300, 500 kg ha−1, alone or with Barrier Si-Ca® (Si—336 dm−3; Ca—207 dm−3) (1 dm3 ha−1). number combinations assessed 16. were compared against control treatment. evaluated plant physiological parameters, dry matter yield, moisture content (protein, fat, starch content), components. highest yields obtained a dose ha−1 (giving an increase 17.5%), 300 plus (+16.4%), (+17.8%). treatments half-rate NPK similar magnitude (on average, +11.9%) full rate (+12.6%) treatments. Doubling contributed 7.8%. had significant beneficial protein fat grain, while it reduced content.
