This study evaluated the effects of ZnO nanoparticles (NP) or Zn salt amendment on sorghum yield, macronutrient use efficiency, and grain Zn-enrichment. Amendments were through soil foliar pathways, under "low" "high" levels nitrogen, phosphorus, potassium (NPK). In amendments, yield was significantly (p ≤ 0.05) increased by both types, albeit insignificantly with soil-applied at low NPK. Across NPK exposure types N K accumulation relative to control plants. Compared K, had a mixed effect P accumulation, depending level pathway, permitted greater retention. Both content, irrespective pathway. These findings suggest nanoenabled strategy for enhancing crop productivity, nutritional quality, efficiency based micronutrient potential implications improved human environmental health.

With increasing global population, innovations in agriculture will be essential for a sustainable food supply. We compare commercial CuO NP to synthesized Cu3(PO4)2·3H2O nanosheets determine the influence of coordinating anion, particle morphology, and dissolution profile on Fusarium oxysporum f. sp. niveum induced disease watermelon. Copper organic acid solutions that mimic complexing agents found plants was increased by 2 orders magnitude relative water. showed rapid initial dissolution, with equilibration after 24 h; exhibited continuous dissolution. In greenhouse study, at 10 mg/L significantly repressed fungal as measured yield 58% decrease progress. Conversely, only yielded significant effects 1000 mg/L. field studies, similar enhanced suppression noted nanosheets, although biomass were variable. The method application factor treatment success, dip being more effective than foliar spray; this is likely due homogeneity coverage during treatment. data show Cu-based nanoscale materials can an strategy crop management but characteristics such coordination environment, important determinants success.

Facile Coating of Urea With Low-Dose ZnO Nanoparticles Promotes Wheat Performance and Enhances Zn Uptake Under Drought Stress

Frontiers in Plant Science, Год журнала: 2020, Номер 11

Опубликована: Фев. 26, 2020

Zinc oxide nanoparticles (ZnO-NPs) hold promise as novel fertilizer nutrients for crops. However, their ultra-small size could hinder large-scale field application due to potential drift, untimely dissolution or aggregation. In this study, urea was coated with ZnO-NPs (1%) bulk ZnO (2%) and evaluated in wheat (Triticum aestivum L.) a greenhouse, under drought (40% moisture capacity; FMC) non-drought (80% conditions, comparison not (control), separate ZnO-NP amendment. Plants were exposed ≤ 2.17 mg/kg 4.34 bulk-ZnO, indicating exposure higher rate of Zn from the ZnO. bulk-ZnO showed similar coating efficiencies 74-75%. Drought significantly (p 0.05) increased time panicle initiation, reduced grain yield, inhibited uptake Zn, nitrogen (N), phosphorus (P). Under drought, average initiation by 5 days, irrespective coating, relative control. contrast, did affect initiation. Compared control, yield significantly, 51 39%, ZnO-NP-coated uncoated urea. Yield increases bulk-ZnO-coated insignificant, compared both control treatments. Plant 24 8% ZnO-NPs; 78 10% bulk-ZnO. treatment reduce time, except Relative (irrespective coating) yield; enhanced significantly. fertilization N P uptake, regardless particle coating. Collectively, these findings demonstrate that enhances plant performance accumulation, thus potentiating field-scale deployment nano-scale micronutrients. Notably, lower inputs crop productivity, comparable This highlights key benefit nanofertilizers: reduction nutrient into agriculture without penalities.

Abstract A synthesis of available agronomic datasets and peer-reviewed scientific literature was conducted to: (1) assess the status micronutrients in sub-Saharan Africa (SSA) arable soils, (2) improve understanding relations between soil quality/management crop nutritional quality (3) evaluate potential profitability application secondary to key food crops SSA, namely maize ( Zea mays L.), beans Phaseolus spp. Vicia faba wheat Triticum aestivum L.) rice Oryza sativa L.). We found that there is evidence widespread but varying micronutrient deficiencies SSA soils simultaneous multiple elements (co-occurrence) are prevalent. Zinc (Zn) predominates list deficient soils. Boron (B), iron (Fe), molybdenum (Mo) copper (Cu) also common. Micronutrient fertilization/agronomic biofortification increases concentrations edible plant organs, it profitable apply fertilizers containing 60–80% cases. However, both profit had large variations. Possible causes this variation may be differences species cultivars, fertilizer type methods, climate initial conditions, chemistry effects on nutrient availability for uptake. Therefore, use efficiency can improved by adapting rates types site-specific management conditions. To make region-wide changes using biofortification, major policy interventions needed.

The societal cost of micronutrient deficiency (MND) or the "hidden hunger" is in millions dollars/year, reducing GDP some countries by as much 11%. Zn an important for both plants and animals. An estimated 17% world population, around 1.1 billion people, are at risk zinc (Zn) deficiency. has been related to adverse pregnancy outcomes, stunted growth, premature deaths, immune system dysfunctions, neuro-behavioral disorders, recently with failure recover from COVID-19. These health risks associated have compelled FAO WHO recommend fortification diet. Correcting a challenge due several reasons. Close half agricultural soils deficient, chemical fertilizers costly ineffective. Developing Zn-rich crops through plant breeding genetic engineering challenging. Zn-dense diet cannot be implemented low-income region most affected Lack consensus among regulatory bodies on defining diagnosing Humans. Awareness other sociocultural issues. Among available solutions biofortification cereal crops, use biofertilizers, development Zn-efficient reduced phytate content. supplements, dietary modification, diversification, especially fish, proposed accessible affordable solutions. programs areas suffering required. Despite suggestions WHO, global efforts combat matching those combating diseases like HIV not place. Coordinated international community, policy-makers, scientists, dieticians, physicians, others, required address issue hidden hunger.
