“…The results showed that the head diameter, head weight, and seed yield per hectare were significantly higher with the spray-dispersion of phosphorus-containing variants than without it (Table 5). This is not surprising considering that P is one of the essential nutrients for plant growth and development, including energy acceleration in plants [15,17], regulation of water uptake and root system development [14], and flower and fruit production, ultimately stimulating sunflower yield and yield-forming parameters [12,13].…”

“…Additionally, P plays a pivotal role in regulating plant energy generation through ATP synthesis and various transport mechanisms [15,16], enhances resistance to environmental stresses, and intensifies physiological reactions [17] while improving overall growth and development [13] as well as increasing crop productivity [18,19]. However, the extensive application of P in agricultural settings can disrupt its natural geochemical cycle, potentially giving rise to imbalanced microorganism populations and concerns of eutrophication [20].…”

One of the challenges in agriculture practices is guaranteeing an adequate and bioavailable phosphorus supply for plants on phosphorus-deficient soils. A promising alternative lies in the utilization of phosphate nano-fertilizers (NFs) through spray applications. Therefore, this short-term study aimed to investigate the yet undetermined widespread impact of P-NFs on crops characterized by broad leaves, an intensive rate of photosynthesis, and belonging to the oilseed plant, sunflower (Helianthus annuus L.). To achieve this, NFs were applied at lower concentrations of various phosphate-based NFs, including (i) nano-hydroxylapatite (nano-Hap) and (ii) a mixture of nano-calcium zinc phosphate and macro-sized parascholzite (nano/macro-ZnPhos), in comparison to the NF-free control. The study was carried out under authentic field conditions during the 2022 vegetation season at the Dolná Malanta site within the Central European Region. The empirical evidence presented herein indicates that the utilization of biocompatible and bioactive nano-Hap, initially engineered for biomedical applications, and nano/macro-ZnPhos, now foliarly applied at reduced concentrations, elicited a statistically significant elevation in quantitative parameters and seasonal physiological responses. The parameters analyzed included head diameter, dry head weight, seed yield per hectare, nutritional seed oiliness, etc. as well as the physiological normalized difference vegetation index (NDVI), stomatal conductance index (Ig), and crop water stress index (CWSI). In terms of agro-ecological terrestrial bio/diversity, it was evident that the nano/macro-ZnPhos was the most hospitable variant for the terrestric insect community, but surprisingly, the agronomically more popular nano-Hap showed only statistically insignificant changes in the diversity of the detected communities. However, the relevance of outcomes highlighted using nano-fertilizers, supporting the concept of precision and sustainable agriculture under field conditions.
