Nano-fertilisers have only recently been introduced to intensify plant production, and there still remains inadequate scientific knowledge on their plant-related effects. This paper therefore compares the effects of two nano-fertilisers common sunflower production under field conditions. The benefits arising from foliar application micronutrient-based zinc oxide fertiliser were compared with those titanium dioxide plant-growth enhancer. Both (ZnO) (TiO2) delivered by in nano-size at a...
It has been shown that the foliar application of inorganic nano-materials on cereal plants during their growth cycle enhances rate plant productivity by providing a micro-nutrient source. We therefore studied effects foliarly applied ZnO nanoparticles (ZnO NPs) Setaria italica L. foxtail millet's quantitative, nutritional, and physiological parameters. Scanning electron microscopy showed NPs have an average particle size under 20 nm dominant spherically shaped morphology. Energy dispersive...
Nanotechnology offers new opportunities for the development of novel materials and strategies that improve technology industry. This applies especially to agriculture, our previous field studies have indicated zinc oxide nanoparticles provide promising nano-fertilizer dispersion in sustainable agriculture. However, little is known about precise ZnO-NP effects on legumes. Herein, 1 mg·L-1 spray was dispersed lentil plants establish direct NP production, seed nutritional quality, stress...
Engineered nanoparticles (ENPs) have potential application in precision farming and sustainable agriculture. Studies shown that ENPs enhance the efficiency of delivery agrochemicals thus, to positively affect environment, thereby improving growth health crops. However, majority research on effects plants agricultural applications been limited controlled laboratory conditions. These conditions do not fully consider various aspects inherent fields under changing weather climate. Some most...
Zinc is among the most in-demand metals in world which also means that a considerable amount of this element released to environment each year as result human activities. A pot experiment was conducted study impact low- and high-dose zinc amendments on plant growth biomass yield, with Calcic Chernozem growing medium barley (Hordeum vulgare L.) model plant. The distribution various parts investigated. Zn (II) added powder bulk ZnO solution nanoparticles ZnSO4 two dosages (3 30 mmol kg−1 soil)...
In environmental and agronomic settings, even minor imbalances can trigger a range of unpredicted responses. Despite the widespread use metal-based nanoparticles (NPs) new bio-nanofertilizers, their impact on crop production is absent in literature. Therefore, our research focused effect spray application gold anchored to SiO2 mesoporous silica (AuSi-NPs), zinc oxide (ZnO-NPs), iron (Fe3O4-NPs) sunflowers under real-world environments. Our findings revealed that biosynthetically prepared...
Since the fate of nanoparticles after their release in environment and possible transfer plants subsequent impacts is still largely unknown, this paper evaluates potential phytotoxic effects up to 20% w/w TiO2 (nTiO2) on barley cultivated hydroponics agar media. The X-ray diffraction analysis confirmed that nTiO2 powder corresponds anatase phase. On medium only high concentrations (10% w/w) induced significant inhibition shoot growth. However, treatment with 1000 mg L−1 did not show any...
Besides many natural factors, soil pH and temperature can have significant effects on the sorption of pharmaceuticals in soils. This is first study, which aimed to evaluate effect ibuprofen soil. Sorption-desorption experiments at 20°C indicated weak retention Sorption was affected by both with latter showing much greater effect. The extent increased decreasing mainly due change speciation from negatively charged ions high neutral form low pH. At 4, distribution coefficient Kd 1.30 l/kg,...
The nanoparticles of TiO2 (TiO2 NP) have been used as a plant-growth stimulant or catalyst in pesticide formulas. However, due to high resistance NP abiotic weathering, dissolved Ti is unlikely act an active compound these preparations. Even if soil acidic, do not dissolve easily and preferably remain undissolved particles. low dissolution rates inorganic the environment make largely unavailable for plants microorganisms. To characterize behavior under different pH conditions, we analyzed...
Our previous studies have shown physiological and yield intensification of selected crops with the application nanoparticles (NPs). However, impact on quantitative, qualitative, parameters maize (Zea mays L.) in field conditions remains highly debated. This study aimed to evaluate effects zinc oxide (ZnO-NPs), gold NPs anchored meso-biosilica (Au-NP-bioSi), titanium dioxide (TiO2-NPs) as biological stimulants under during vegetation season 2021 Central European region. The assessed number...
The action-to-reaction dynamics of next-generation nanofertilizers (NFs) towards field crops are currently being addressed in precision and sustainable agriculture. Therefore, our aim was to evaluate the effects foliar application ZnO nanoparticles (ZnO-NPs) or their combination with hybrid nanoporous biosilica mixed yeast (ZnSi-bio) for soybean plants’ selected production physiological indices comparison an NF-free control. experiment conducted at eco-friendly concentrations Veľký Krtíš,...
Ganoderma resinaceum Boud. is commonly found in Mediterranean region, but rarely Western, Central or Eastern Europe. It a parasitic basidiomycetous fungus causing stem decay—especially urban trees. A collection of nine fungal specimens from Slovakia (Central Europe), morphologically identified as G. resinaceum, was recently studied on the basis sequence data internal transcribed spacer (ITS) regions. Analyses showed that collections clustered into two separate groups. In this study—for first...
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 utilization phosphate nano-fertilizers (NFs) through spray applications. Therefore, this short-term study aimed to investigate yet undetermined widespread impact P-NFs crops characterized by broad leaves, intensive rate photosynthesis, belonging oilseed plant, sunflower (Helianthus annuus L.). To achieve this, NFs...
Adding the humic acid coating to nanoparticles of zinc oxide (ZnO-NP) may improve properties necessary for their colloidal stability. To show how affects ZnO-NP, three differently sol-gel synthesized ZnO-NP were synthesized: pristine without (p-ZnO-NP) and coated at two different initial concentrations 20 mg/L (HA20-ZnO-NP) 200 (HA200-ZnO-NP) acids in starting solution. All found be nanocrystals mineral zincite exhibiting wurtzite crystal symmetry. Transmission electron microscopy showed...
Zinc oxide nanoparticles (ZnO NPs) belong to the most widely used in both commercial products and industrial applications. Hence, they are frequently released into environment. Soil fungi can affect mobilization of zinc from ZnO NPs soils, thus heavily influence mobility bioavailability there. Therefore, ubiquitous soil fungus Aspergillus niger was selected as a test organism evaluate fungal interaction with NPs. As anticipated, A. strain significantly affected stability particulate forms...
