Efficacy of Mineral And Nano Fertilizers on Yield and Quality of Sugar Beet crop cv. Karam., (Beta vulgaris, L)
Summary
This Egyptian field study evaluated nano fertilizers versus conventional mineral fertilizers for sugar beet production over two growing seasons. The study is focused on agricultural crop science and is not related to microplastic research.
Two field experiments were conducted at the experimental farm of Delta Sugar Company at El-Hamoul area in North of Egypt, Kafr El-Sheikh Governorate, Egypt during 2020/2021 and 2021/2022 winter seasons, to study the effect of Nano and normal fertilizer on yield and quality of sugar beet, cv. Karam., (Beta vulgaris, L) The experiments were carried out in strip plot design, where the vertical plots were devoted to soil application of fertilizers, while the horizontal plots were assigned to foliar fertilization treatments. The obtained results indicated that fertilized sugar beet plants with 50kgN+green Foliar (20L/fed) as soil fertilization gave the highest relative growth rate (RGR), net assimilation rate (NAR) and crop growth rate (CGR), root length, root fresh weight and, sucrose percentage, root yield /fed, and sugar yield /fed as compared with 100KgN/fed as well as 50kgN+green Foliar(10L/fed) treatments in both seasons. While, the highest purity percentage was found with 50kgN+green Foliar (10L/fed) treatment, on the other hand, applied 100 kg N /fed gave the lowest purity percentage 88.40 and 89.48 % in 2021 and 2021/2022 seasons, respectively. Results exhibited that spraying sugar beet plants with Malty green (2.5L/fed.) +Nano calcium (2.5L/fed.) gave the highest values of all studied traits in both seasons. On the contrary, sprayed sugar beet plants with tap water (control) gave the lowest values of all studied traits in both seasons. RY traits depicted a significant positive correlation with NAR, CGR and SY (p<0.05) in 2020/2021. However, in the second season of 2021/2022, RY showed a significant positive correlation with all the studied traits as RGR, NAR, RL, FW, sucrose %, purity%, and SY, under four foliar fertilizers and three soil fertilizers in both seasons. In conclusion, fertilizing sugar beet plants with 50kgN/fed +Green Foliar (20L/fed) as a soil address and spraying by Malty green (2.5L/fed.) + Nano calcium (2.5L/fed.) treatment to maximizing root and sugar yields of sugar beet plants cv. Karam at El-Hamoul area condition, Kafr El-Sheikh Governorate, Egypt.

Not relevant to microplastics — this is a review comparing traditional, conventional, and nano-technology-based fertilisation methods in agriculture.
The challenge of nanotechnology in the field of agricultural applications: Nanofertilizers as an emerging technology
This systematic review covers the development and applications of nanofertilizers — nano-scale nutrient delivery systems for agriculture — as an emerging and more efficient alternative to conventional fertilizers. Precision agriculture using nanotechnology could reduce the reliance on plastic-coated slow-release fertilizers that contribute microplastics to soil.
Nanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination. While not directly about microplastics, the research is relevant because nanoparticles and microplastics share similar size ranges and behaviors in soil, and understanding how tiny particles interact with plants helps scientists assess both the risks and potential benefits of nanoscale materials in agriculture.
How to improve crop photosynthesis more efficiently using nanomaterials: Lessons from a meta-analysis
Researchers analyzed dozens of studies and found that applying nanomaterials to crops can boost photosynthesis — the process plants use to grow — especially under drought and salt stress conditions, though they caution that lab results may not always translate to real farm fields and that nanoplastics in the soil can reduce these benefits.
A Review on Crop Responses to Nanofertilizers for Mitigation of Multiple Environmental Stresses
This review examines how nanoscale fertilizers can help crops survive environmental stresses like drought, salt, and pollution by improving nutrient delivery at the cellular level. While focused on agricultural benefits, the research is relevant to microplastics because nanofertilizers may help plants cope with microplastic-contaminated soil. However, the authors caution that widespread use of nanoparticles in farming raises its own questions about potential effects on the environment and human health.
