“…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.…”

The mineral nutrients are absorb from the soil by the roots, these are either macro or micro nutrients. Zinc is micro nutrients that help in several physiological process of plants and help in phyto hormone synthesis. The present Study includes the synthesis of ZnOPs by using Zinc oxalate decomposing method and these particles are characterized by UV-vis spectroscopy, and size was analyzed by Zeta analyzer. ZnOPs size was analyzed 65 nm. Seed germination was done by paper towel method. Soaking of seed was done in 100ppm, 500ppm and 1000ppm of ZnOPs and 100 ppm of ZnO supplement solution. After 5 day germination, germination percentage and seed vigor index (SVI) was calculated. It was observed that seed germination at 100 ppm is maximum in both the seed of Lentil (Lens esculentum Linn) and Chick pea (Cicer arietinum Linn). Seed vigor index was found increased at concentration of 100ppm. Presented study inferred that zinc provided as nanoparticle absorb more prominently than the traditional zinc supplement available in market at low concentration as the ZnOPs concentration increases the germination and seed vigor index retarded so it can be proposed that micronutrient in nano particles based formulation at lower concentration can provide better result in agriculture production.

“…Similar results were observed by [46] in onion where flowering duration was reduced by 12-14 days at low concentration but phytotoxic effects at high concentrations were seen. Also, [47] observed the effect of seed polymer coating of Zn and Fe NPs at different concentrations in pigeonpea. Higher seed germination, seedling growth, field emergence, seedling vigour index, dehydrogenase and amylase activity were observed at lower concentration of Zn and Fe NPs over their bulk forms and control, whereas seed germination and seedling growth was inhibited at higher concentrations.…”

India being an agricultural country, more than 80% population of rural India depends on agriculture and its associated activities for their living. To satisfy the requirements of Indian population, there is need for adequate crop yield. But due to urbanisation, pollution, biotic and abiotic stresses, unavailability of micronutrients etc. there are various constraints on seed germination and crop yield. The present review highlights the problems associated with germination and growth of plants. It discusses on seed priming technology that can synchronise seed germination and improve vigour, leading to better crop establishment and yield. Seed priming stimulates the processes involved in metabolism which prevents seed deterioration, breaks dormancy and induces systemic resistance against biotic and abiotic stresses. It explains physiological and biochemical changes occurring in seeds on priming. Extensive study using different seed priming techniques viz. hydro-priming, halopriming, osmo-priming, matrix priming, osmohardening, on-farm priming, hormone priming, nutripriming, biopriming nanoparticle priming etc. has been carried out. Studying the use of different techniques and their need put an insight in the new research area of bionanoseed priming produced by amalgamating nanofertilisers and plant growth promoting rhizobacterias, to improve the productivity of crops.

“…In this study. The higher concentrations (150-200 ppm) showed adverse effect on the seedling length over the 125 ppm, this might be due to excess absorption of the NPs which resulted from penetration of NPs in to shoot and root cell wall and plasma membrane of epidermal layers and accumulation in vascular tissues thereby affected cell division and cell elongation (Korishettar et al, 2016). Thus, the SNPs, may play vital role for improvement in seed germination characteristics, it may be easily visualised with their direct and indirect involvement in the root and shoot length.…”
