“…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.

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.

Abstract‘Pre‐sowing seed priming’ and ‘pre‐transplanting root priming’ are promising strategies to improve agriculture productivity. Farmers, seed production enterprises, and seedling producers constantly search for economic priming agents that help improve yield and crop health. Recently, several nanomaterials have emerged as economical seed and root priming agents, with nanoiron pyrite standing out as a particularly promising molecule. The observed enhancement in germination of nano‐pyrite treated seeds across various plant species indicate a shared underlying mechanism. We conducted evaluations of gibberellic acid (GA) and abscisic acid (ABA) content in red radish and soybean seeds subjected to nano‐pyrite priming revealing a notable increase in the GA: ABA ratio compared to the control group. In addition, mature red radishes cultivated from nano‐pyrite primed seeds exhibited elevated anthocyanin content and a remarkable 25.46% increase in yield. The aqueous pyrite suspension utilised in the process generates trace peroxide, and we propose that this trace peroxide plays a crucial role in orchestrating the increased GA: ABA ratio, anthocyanin content, and crop yield. These results position nano‐pyrite as a plant hormone regulator, effectively mimicking the seed hormo‐priming strategy. Considering the widespread presence of pyrite in the earth's crust, using pyrite as a commercial seed and root priming agent emerges as a potentially sustainable approach to enhance food production.
