Influence of metal uptake from fly ash on the growth of Jatropha Curcas plant: Bulk utilization approach

Impact of high and low concentration of fly ash amended soil on physico‐chemical properties of biodiesel produced from Jatropha curcas

“…33,34 In earlier research work, percent absorption of metals from base materials with respect to metal concentration before plant growth and metal concentration after 5 years of plant growth were determined. 17,35 Jatropha curcas has an inherent biochemical property to survive in stress conditions; this has been observed in the present study where 25% of fly ash in the base material is an optimal condition for higher yield of seeds due to the presence of the limited number of metals in fly ash. Furthermore, correlation analysis showed that biodiesel production was positively correlated with metal uptake by plants from different base materials.…”

“…In several reports, it was observed that Jatropha curcas has very high ability to accumulate heavy metals from the base material without altering the plant growth and results in a hyper‐accumulator of zinc and iron 33,34 . In earlier research work, percent absorption of metals from base materials with respect to metal concentration before plant growth and metal concentration after 5 years of plant growth were determined 17,35 . Jatropha curcas has an inherent biochemical property to survive in stress conditions; this has been observed in the present study where 25% of fly ash in the base material is an optimal condition for higher yield of seeds due to the presence of the limited number of metals in fly ash.…”

“…The sample size of this pot system was 20 for each base material. This 5‐year study comprised of preparation of base materials with different compositions of soil and fly ash, study of morphological and biochemical parameters with respect to plant growth performance, 15,16 analysis of soil properties and metal profile before and after plant growth, 15,17 seed collection, seed oil extraction, preparation of biodiesel and characterization of biodiesel according to ASTM standards.…”

Coal fly ash and nitrogen application as eco-friendly approaches for modulating the growth, yield, and biochemical constituents of radish plants

“…Heavy metals in FA would affect plant productivity, either directly or indirectly. Some of the direct and indirect consequences include reduced photosynthetic rate, seed germination, protein content, pigment content, and so on, whereas indirect consequences include increased reactive oxygen species (ROS), activity in antioxidant enzymes, function loss and membrane lipid peroxidation ( Raj and Mohan, 2018 , Moustafa-Farag et al, 2020 ).…”

Effects of Fly Ash Amended Soil on Biochemical Attributes and Antioxidant Responses of Medicinally Potent Plant Calendula Officinalis

“…Even though FA has many advantages as an ameliorant for agricultural soil applications, but due to presence of some amounts of heavy (toxic) elements in FA, balanced use of FA in agriculture is highly important (Gorai 2018).The utilization of FA as an amendment in soil for better growth and yield has been studied for different plant species. Mahale et al 2012 observed that use of FA in agriculture at 60% concentration enhances the wheat yield (Triticum aestivum L.), 20% was found better for mung bean (Vigna radiata) (Gupta and Sinha 2009) and 50% gave good results for Jatropha curcas (Raj and Mohan 2018). This proves that the concentration of suitable FA application in the soil differs from species to species.…”
