Massive accumulation of heavy metals in agricultural land as a result of enhanced levels of toxicity in the soil is an emerging global concern. Among various metals, zinc contamination has severe effects on plant and human health through the food chain. To remove such toxicity, a nanotechnological neutralizer, cobalt oxide nanoballs (Co3O4 Nbs) were synthesized by using the extract of Cordia myxa. The Co3O4 Nbs were well characterized via UV-vis spectrophotometry, scanning electron microscopy, and X-ray diffraction techniques. Green-synthesized Co3O4 Nbs were exposed over Acacia jacquemontii and Acacia nilotica at different concentrations (25, 50, 75, and 100 ppm). Highly significant results were observed for plant growth by the application of Co3O4 Nbs at 100 ppm, thereby increasing the root length (35%), shoot length (48%), fresh weight (44%), and dry weight (40%) of the Acacia species with respect to the control. Furthermore, physiological parameters including chlorophyll contents, relative water contents, and osmolyte contents like proline and sugar showed a prominent increase. The antioxidant activity and atomic absorption supported and justified the positive response to using Co3O4 Nbs that mitigated the heavy-metal zinc stress by improving the plant growth. Hence, the biocompatible Co3O4 Nbs counteract the zinc toxicity for governing and maintaining plant growth. Such nanotechnological tools can therefore step up the cropping system and overcome toxicity to meet the productivity demand along with the development of agricultural management strategies.

Nanoteknolojik gelişmelere paralel olarak günümüzde nanopartiküllerin ortamlardaki konsantrasyonları gittikçe artmaktadır. Çevre üzerindeki etkileri yeterince bilinmeyen bu materyallerin tanınması ve etkilerinin tespiti önem arz etmektedir. Bu çalışma, Kızılçamın (Pinus brutia Ten.) ana yayılış sahası dışında bulunan doğal kızılçam meşceresinde gerçekleştirilmiştir. Yarı kurak iklimin hâkim olduğu Ankara-Beypazarı yöresinde; Silika, Fe2O3, Fe3O4, ZnO, TiO2, Au, CuO ve Ag nanopartiküllerinin (NPs) beş farklı doz seviyesinde (çok yüksek, yüksek, orta, düşük, çok düşük) açık alan koşullarında çimlendirilen tohumlarının fidan gelişimi ve fidan yüzdesi parametrelerine etkisi araştırılmıştır. Üç tekrarlı kurulan denemede elde edilen fidan boyu (FB), kök boğazı çapı (KBÇ) ve fidan yüzdesine (FY) ait verilere varyans analizi ve Duncan testi uygulanmıştır. Araştırma sonucunda; NP çeşit ve doz faktörleri ile her iki faktörün etkileşimi FB, KBÇ ve FY üzerinde %95 güven düzeyinde anlamlı farklılık oluşturmuştur. NP çeşit ve dozları 1+0 yaşlı kızılçam FB ve KBÇ gelişimi ile FY üzerinde olumsuz etki yapmıştır. Buna karşılık, kontrol fidanlarının boy ve çap gelişimi ile FY değerlerinin daha yüksek olduğu tespit edilmiştir. Kontrol işlemi fidanlarının ortalama FB değeri, Fe2O3 NP uygulaması boy değerlerine göre %35 yüksek, KBÇ değeri ise Cu NP uygulamasına göre %70 civarında daha yüksek olduğu tespit edilmiştir.

Plants are subjected to a wide range of abiotic stresses, such as heat, cold, drought, salinity, flooding, and heavy metals. Generally, abiotic stresses have adverse impacts on plant growth and development which affects agricultural productivity, causing food security problems, and resulting in economic losses. To reduce the negative effects of environmental stress on crop plants, novel technologies, such as nanotechnology, have emerged. Implementing nanotechnology in modern agriculture can also help improve the efficiency of water usage, prevent plant diseases, ensure food security, reduce environmental pollution, and enhance sustainability. In this regard, nanoparticles (NPs) can help combat nutrient deficiencies, promote stress tolerance, and improve the yield and quality of crops. This can be achieved by stimulating the activity of certain enzymes, increasing the contents (e.g., chlorophyll) and efficiency of photosynthesis, and controlling plant pathogens. The use of nanoscale agrochemicals, including nanopesticides, nanoherbicides, and nanofertilizers, has recently acquired increasing interest as potential plant-enhancing technologies. This review acknowledges the positive impacts of NPs in sustainable agriculture, and highlights their adverse effects on the environment, health, and food chain. Here, the role and scope of NPs as a practical tool to enhance yield and mitigate the detrimental effects of abiotic stresses in crops are described. The future perspective of nanoparticles in agriculture has also been discussed.
