Seed polymer coating with Zn and Fe nanoparticles: An innovative seed quality enhancement technique in pigeonpea

Abstract

A laboratory study was undertaken to know the effect of seed polymer coating with Zn and Fe nanoparticles (NPs) at different concentration (10, 25, 50, 100, 250, 500, 750 and 1000 ppm) in pigeonpea at Department of Seed Science and Technology, UAS, Raichur. Among the treatments seed polymer coating with Zn NPs at 750 ppm recorded significantly higher seed germination (96.00 %), seedling length (26.63 cm), seedling dry weight (85.00 mg), speed of germination (32.95), field emergence (89.67 %), seedling vigour index (2556), dehydrogenase activity (0.975 OD value) and α-amylase activity (25.67 mm) and lowest abnormal seedlings (2.50 %) over their bulk forms and control followed by Fe and Zn NPs at 500 ppm. However, in contrast to beneficial effects, these NPs also shown inhibitory effect on germination and seedling growth at higher concentration (nano Zn >750 ppm and nano Fe > 500 ppm). Hence, from the results it is concluded that Zn NPs at 750 ppm can be used to enhance quality of the pigeonpea seeds.

Comparative Efficacy of Zn Supplement and Zinc Oxide Nanoparticles Over the Seed Germination of Lentil and Chick Pea

“…The effect of Zn nano particle also described by fact that it increase the higher precursor activity for producing the higher biomolecules. Similar findings have also reported positive impact of ZnO NPs in different crops [11][12][13][14][15][16] . Effects of ZnONp was also observed on shoot length, root length and on seed vigor index.…”

Electrospun α-Terthienyl Nanofibres as a Sustainable Alternative to ChemicalNematicides: Controlled Release, Eco-Safety, and Enhanced Plant Protection

“…Biosafety evaluations showed no harmful effects on beneficial organisms such as Eisenia eugeniae, highlighting its eco-friendly profile [31]. Additionally, in silico docking studies validated α-terthienyl's dual target mechanism against key nematode proteins (32), while seed germination and pot culture trials demonstrated improved plant growth, nematode suppression [33]&[34],and cost effectiveness compared to conventional carbofuran treatments. These results collectively position α-terthienyl nanofibre encapsulation as a sustainable, effective, and environmentally responsible alternative for nematode management in agriculture.…”
