Impact of the low and high concentrations of fly ash amended soil on growth, physiological response, and yield of pumpkin (Cucurbita moschata Duch. Ex Poiret L.)

Gufran Ahmad et al.

Summary: The study found that moderate levels of fly ash can be used as fertilizer to improve crop yield and growth in a sustainable manner. However, excessive levels of fly ash may have negative effects on plant growth and development.

Assessment of leaf morphological characteristics, phenolics content and metal(loid)s concentrations in Calendula officinalis L. grown on fly ash amended soil

Ayushi Varshney et al.

Summary: The experiment analyzed the impact of different doses of fly ash in soil on the growth performance, phenolics, flavonoids, and elemental uptake of Calendula officinalis. The results showed that low ratios of fly ash amendment to soil improved plant growth, while high fly ash doses tended to decrease growth parameters. A 40% concentration of fly ash did not contain toxic levels of elements and resulted in improved growth and yield. Additionally, increasing fly ash application up to 60% showed an increasing trend in phenolics and flavonoids in leaves.

Optimization of eco-friendly novel amendments for sustainable utilization of Fly ash based on growth performance, hormones, antioxidant, and heavy metal translocation in chickpea (Cicer arietinum L.) plant

Sudhir K. Upadhyay et al.

Summary: This study focused on evaluating the maximum utilization of flyash with manure in acidic soil on chickpea growth and toxic heavy metal impacts. The results showed that 40% flyash supplementation with manure enhanced chickpea growth in slightly acidic soil while reducing the translocation of toxic metals in the edible parts of the plant.

Growth and antioxidant responses in plants induced by heavy metals present in fly ash

Ayushi Varshney et al.

Summary: Fly ash is a solid waste generated from coal combustion in thermal power plants, which is both harmful to the environment and beneficial for agricultural crops. Utilizing fly ash as a soil ameliorant enhances crop productivity by improving soil properties, but heavy metals present in fly ash can pose phytotoxicity to plants and induce oxidative stress. Understanding the antioxidative system of various plant species in response to heavy metal damage is crucial for determining the optimal concentration of fly ash for plant cultivation in agriculture.
