“…In the study by Srivastava et al, iron pyrite NPs induced a marked increase in the growth of spinach sprouts [12]. Iron pyrite NPs also facilitated a denser network of roots and a significantly (~2.5 times) higher yield in both chili and marigold plants [13]. These NPs served as a suitable equivalent of nitrogen, phosphorus, and potash fertilizer for the production of rice, a staple food crop [14].…”

There is an emerging scientific interest in the use of nanoparticle fertilizers for enhanced agricultural and bioenergy crop production to meet the growing food and energy demands of the world. The objective of designing the nanoparticle fertilizers is to effectively deliver the required nutrients for the plants without adding large quantities of fertilizer to the environment. However, most reports on nanoparticle fertilizers so far, involved the addition of nanoparticles to the hydroponic system or the soil. In this study, we report a new modified seed presoak strategy using a drop of Fe-enriching hematite nanoparticle dispersion to enhance plant growth and production in four different legume species, i.e., chickpea, green gram, black bean, and red bean. The hematite nanoparticle fertilizer drop promoted a 230-830% increase in plant growth with green gram showing the highest increase, based on our prolonged and statistically reliable growth studies. In general, we observed an increase in the survival span of plants, a twofold increase in fruit production per plant, nearly two times faster fruit production, and healthy secondgeneration plants with the nanoparticle treatment; however, there were slight species-specific variations. We used a novel multimodal material characterization approach combining three techniques, hyperspectral imaging, Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma optical emission spectroscopy (ICP-OES), to evaluate the internalization and transport of the nanoparticle fertilizer within the plants. Our results indicated that the hematite nanoparticles were transported through the roots and stems and were localized in the leaves after 10 days of growth in pots of soil. Therefore, the modified seed presoaking method using a drop of hematite nanoparticle will be highly attractive in enhancing plant growth and health, while minimizing environmental impacts.

“…A few other reports exist in the literature showing growth‐promoting effects of iron disulfide nanoparticles on chick pea ( Cicer arietinum ) (Srivastava, Das, Kusurkar, et al, 2014) and spinach ( Spinacia oleraceae ) (Srivastava, Das, Das, et al, 2014) at a concentration of 80 μg/ml. Growth‐promoting effects of nanopyrite has been explored in other crops also (Das et al., 2018; Jangir, Bharadwaj, Srivastava, & Das, 2020; Jangir, Bhardwaj, & Das, 2020; Jangir, Bhardwaj, Srivastava, & Das, 2019; Jangir, Das, et al, 2019).…”

Manganese sulfide nanospheres (MnS‐NSs) prepared in situ via sonochemical process were characterized to investigate the effect of nanoscale MnS on antifungal potential against mycopathogens of rice viz. Fusarium verticillioides, Drechslera oryzae and Curvularia lunata. MnS‐NSs dispersed in aqueous medium resulted in significant inhibition of growth of all the test fungi (ED50 ≤ 18 μg/ml) at concentration much lower than standard commercial fungicides (captan and carbendazim with ED50 ≥ 230 μg/ml) against respective fungi. The maximum per cent inhibition (98 ± 1.4) was recorded against C. lunata with a minimum ED50 value of 14 μg/ml, followed by D. oryzae and F. verticillioides with ED50 values of 17 and 18 μg/ml, respectively. Nanopriming of rice seeds with MnS‐NSs at 35 μg/ml for 8 hr resulted in significant reduction in seed rot (76%) and seedling blight (89.13%) along with enhancement in percent germination, root length, shoot length, dry weight and vigour index of seedlings by 33.7%, 55%, 66.3%, 85.3% and 89.3%, respectively, compared with control. Hydropriming of seeds was found to control the seed health parameters less effectively than nanopriming.

“…The nano pyrite seed treatment gets nullified by co-treatment with an antioxidant nanomaterial, viz., cerium oxide 32 . Recently Jangir et al discovered that upon treating the roots of chili, marigold, cabbage, cauliflower, and tomato in an aqueous suspension of nano pyrite for three hours, a significant increase in yield was observed [33][34][35][36] .…”

Our reliance on synthetic agrochemicals has detrimental effects on the environment and living species. To restore the ecological balance, we need to explore strategies to minimize agrochemicals’ use without compromising agricultural production. Nano-formulations help lower dosages of agrochemicals, leading to the emergence of nano-agriculture. Judicious use of nanomaterials for enhancing plant metabolic performance and yield remains a challenge. Here, we have achieved the same by root treatment of the onion crop with nanopyrite (FeS2) and further organic goat manure fertilizer application. We report an increase in yield through root treatment with nano-pyrite plus soil application of goat dropping (Test) as compared to the use of goat dropping alone (Control). The total biomass of the test sample was 4.75 kg (n=86), while control samples weighed 3.5 kg (n=86). The total bulb weight for the control and test was 2.6 kg and 3.6 kg, respectively. We observed a yield-boosting effect of root treatment with nanopyrite in onion. There is a significant increase in the anthocyanin content in test bulbs and flavonol content in test leaves. We have integrated two types of farming systems: organic and nano-agriculture to bolster the metabolic fitness of the onion (Allium cepa) and achieve sustainable food production.
