“…In our study, the root and shoot dry weights, of leaves per plant, and roots length of S. nigrum plants were significantly enhanced with the N-fertilizer application. In our current study, disparity in the Cd absorption in differently treated plants was observed, which is in line with the results of Ye et al [41], who described an enhanced absorption of Cd and a phytoextraction efficiency of T. patula after N-fertilizer treatment. Moreover, our results are also supported by Yang et al [42].…”

Heavy metal contamination is currently a major environmental concern, as most agricultural land is being polluted from municipal discharge. Among various other pollutants, cadmium (Cd), one of the most harmful heavy metals, enters into the food chain through the irrigation of crops with an industrial effluent. In the present study, a pot experiment was designed to assess the effect of different nitrogen (N)-fertilizer forms in the phytoremediation of Cd through Solanum nigrum L. Two types of N fertilizers (NH4NO3 and urea) were applied to the soil in different ratios (0:0, 100:0, 0:100, and 50:50 of NH4NO3 and urea, individually) along with different Cd levels (0, 25, and 50 mg kg−1). The plants were harvested 70 days after sowing the seeds in pots. Cadmium contamination significantly inhibited the growth of leaves and roots of S. nigrum plants. Cadmium contamination also induced oxidative stress; however, the application of N-fertilizers increased the plant biomass by inhibiting oxidative stress and enhancing antioxidants’ enzymatic activities. The greatest plant growth was observed in the urea-treated plants compared with the NH4NO3-treated plants. In addition, urea-fed plants also accumulated higher Cd concentrations than NH4NO3-fed plants. It is concluded that urea is helpful for better growth of S. nigrum under Cd stress. Thus, an optimum concentration of N-fertilizers might be effective in the phytoremediation of heavy metals through S. nigrum.

“…However, other pot-culture experiments showed that N fertilizer signi cantly improved the biomass and Cd phytoremediation e ciency in Tagetes patula grown in Cd-contaminated soil (Ye et al, 2019). Nitrogen supply, particularly nitrate, sharply increased Cd extraction of T. caerulescens (Schwartz et al, 2003), while urea signi cantly enhanced Cd phytoextraction by Carpobrotus rossii (Liu et al, 2016), which has further demonstrated that the addition of N fertilizer to soil plays an important role in Cd phytoaccumulation e ciency.…”

It is very important to increase phytoremediation efficiency in practice in suitable climatic conditions for plant growth by multiple harvests. Solanum nigrum L. is a Cd hyperaccumulator. In present experiment, after applying different types of N fertilizers (NH4HCO3, NH4Cl, (NH4)2SO4, CH4N2O), root and shoot biomasses and Cd phytoextraction efficiency of S. nigrum effectively improved (P < 0.05), whereas shoot biomasses of S. nigrum harvested at the first florescence stage plus the amounts at the second florescence stage were higher than those at the maturation stage, which indicated that S. nigrum Cd phyto-accumulation efficiency was higher in double harvests at florescence stages compared to a single harvest due to the lack of a clear change in Cd concentration (P < 0.05). The pH value and extractable Cd contents showed no changes, regardless whether N fertilizer was added or not at different growth stages. In addition, after N fertilizer supply, H2O2 and MDA contents in S. nigrum in vivo were lower compared to CK; Similarly, the concentration of proline was decreased as well (P < 0.05). As one of the antioxidant enzymes, CAT activity in S. nigrum shoots, harvested at different growth periods after 4 types of N fertilizer application, obviously decreased, while POD and SOD activities increased (P < 0.05). Our study demonstrated that (NH4)2SO4 treatment exerted the most positive effect and the CH4N2O the second-most positive effect effect on S. nigrum Cd phytoremediation efficiency in double harvests at florescence stages and the growth conditions were better than others.

Importance of medicinal plants to health care has been great and herbal preparations are being produced at industrial scale particularly in developing countries. The plant products obtained have a long history of use in therapeutics, aromatherapy and food depending on the chemical constituents and their bioactivity. In the recent past, marigolds have received a great attention in scientific research, because of their multiple use and also the information available about their phytochemistry and bioactivity. Tagetes species commonly known as marigold is native to Mexico, being used for medicinal and ornamental purposes. The plant is useful due to its unique phytoconstituents for a range of diseases and disorders and is reportedly effective against piles, kidney troubles, muscular pain, ulcers and wound healing and the flowers are helpful in fever, stomach and liver complaints and also in eye diseases. In India, marigold is also extensively used on religious and social occasions such as in the beautification of mandaps and pooja places; offerings at temples; marriage decorations and landscape planning due to variable size and colour of its flower. Present review is an effort to bring together the different strategies developed for the growth and cultivation of marigold, its ecophysiological and remediation relevance under a variety of environmental conditions and possible allelopathic potential. It includes reports on pharmacological aspects like antibacterial, antifungal, larvicidal, hepatoprotective, insecticidal, mosquitocidal, nematicidal, wound healing, antioxidant, anticancer and antidiabetic properties/activity of Tagetes.
