“…If it cannot be used directly and if it increases the mobility and bioavailability of metals in the soil, it can still be used in remediation, but indirectly. Specifically, it could be used in phytoremediation allowing plants to increase their accumulation as shown by Chand et al [103] and Chand et al [104]. Consistent with this possible role, it could also play a role in biofortification.…”

Industrialization and urbanization have led to an increased accumulation of waste materials that are transformed into a nutrient-rich and high-quality product called vermicompost by the vermicomposting process. Vermicomposting is an ecofriendly and economically favorable biotechnological process that involves the interaction of earthworms and microorganisms. Due to the importance of this process and its great potential in dealing with the consequences of waste accumulation, this review aims to provide key insights as well as highlight knowledge gaps. It is emphasized that there is a great challenge in understanding and clarifying the mechanisms involved in the vermicomposting process. The optimization of the factors affecting the possible application of vermicompost is crucial for obtaining the final product. Information on the composition of bacterial communities, amount of vermicompost, effect on heavy metal content, plant pathogens, diseases and organic waste selection is here recognized as currently the most important issues to be addressed. By answering these knowledge gaps, it is possible to enable wider utilization of vermicompost products.

“…Latest studies showed that wild marigold may be a profitable EO crop for the western Himalaya and probably in the north India as this crop remains unaffected by biotic and abiotic factors and the essential oil obtained from hilly region are rich in ocimene and dihydrotagetone which are the major compounds used in perfumery and flavor industries ( Rathore et al, 2018 ). Plant fertilization in Tagetes was not yet examined in the western Himalayas, however, previous studies on plant nutrients have shown a substantial effect in general ( Sunitha and Hunje, 2010 ; Negahban et al, 2014 ; Chand et al, 2015 ) and nitrogen (N) fertilization ( Omidbaigi et al, 2008 ; Singh et al, 2008 ; Singhal and Sharma, 2010 ) on wild marigold production and quality. Sulfur (S) is an important macronutrient in plants due to its important function in synthesis of proteins, as it is an important part of cysteine and methionine amino acids and coenzymes ( Marschner, 1999 ).…”

Fertilization plays an irreplaceable role in raising crop yields; however, there are issues with unnecessary and blind use of chemical fertilizers, which raise the risk of contamination in the atmosphere. It is hypothesized that fertilization of nitrogen (N) and sulfur (S) will together improve the essential oil (EO) yield and composition of Tagetes minuta L. Thus, 2 years field experiment were carried out to evaluate the outcomes of N (0, 60, 90, and 120 kg ha–1) and S levels (0, 20, 40, and 60 kg ha–1) on T. minuta during 2018 and 2019. The growth, biomass, EO content and composition were influenced (P = 0.05) by N and S fertilization. N at 120 kg ha–1 and S at 60 kg ha–1 registered higher biomass (183.89 and 178.90 q ha–1, respectively) and EO yield (102.09 and 88.60 kg ha–1, respectively), than control. Stomatal density reduced significantly with increase of N and S levels, however, density of oil glands substantially increased with S at 40 and 60 kg ha–1. The major component of EO (Z-β-ocimene) significantly increased with 120 kg N ha–1 (42.59%) and 60 kg S ha–1 (42.35%), respectively. Available nutrients in soil and plant tissues substantially increased with N and S fertilization upto 120 and 60 kg ha–1, respectively. The highest nutrient use efficiency traits were recorded at 60 kg N ha–1 and 20 kg S ha–1. It was concluded that 120 kg N ha–1 and 40 kg S ha–1 can be proposed for T. minuta as a result of agronomic responses, which serves as a sustainable means of cropping.

“…Nickel (Ni) plays a vital role in nitrogen (N) metabolism as a biologically essential nutrient, but it becomes toxic to the plants at higher concentrations. The effect of Ni and vermicomposting on plant growth, essential oil composition, and mineral element accumulation of wild marigold suggests that the growth of wild marigold with vermicomposting can be used as a strategy for rehabilitation and Ni phytoremediation (Chand et al, 2015). The high concentration of Ni in leaves than roots of wild marigold suggests that it can be used as a potential crop for Ni phytoremediation.…”

Wild marigold has a growing demand for its essential oil in the flavor and fragrance industries. It can be grown over a broad range of climates, but the changing climatic conditions lead to abiotic stresses, thus restricting its productivity. Abiotic stresses at elevated levels result in the reduction of germination, growth, and essential oil quality of wild marigold leading to heterogeneous and inferior grades of “Tagetes oil.” Drought, salinity, and heavy metal stress at elevated levels have common effects in terms of ROS formation, which are the major cause of growth deterioration in wild marigold. Temperatures above 35°C inhibit seed germination. Irradiance stress reduces the biomass and essential oil yield. Waterlogging adversely affects the survival of wild marigold in high rainfall regions. The application of plant nutrients (fertilizers) modulates the biomass and essential oil yield. Wild marigold employs multiple tolerance mechanisms to cope up with the adverse effects of abiotic stresses such as the increased activity of antioxidants to maintain cellular redox homeostasis, enhanced lipid peroxidation in the cell membrane to maintain cell wall architecture, production of secondary metabolites, and accumulation of osmolytes. In this review, we tried to understand how abiotic stresses affect wild marigold. Understanding the physiological changes and biochemical characteristics of stress tolerance will contribute to the development of stress-tolerant lines of wild marigold.
