Growth, biochemical, and antioxidant response of beetroot (Beta vulgaris L.) grown in fly ash-amended soil

Abstract

A pot experiment was conducted under net house conditions to study the ameliorative role of different levels of fly ash as a soil amendment, on the growth markers, biochemical attributes, and the antioxidant enzyme activity of beetroot. Seeds of beetroot were sown in earthen pots containing growth substrate, consisting of field soil amended with different levels of fly ash (0%, 5%, 10%, 15%, 20%, and 25% weight/weight). Beetroot grown in 15% fly ash-amended soil had significantly (p ≤ 0.05) higher plant growth and pigment content as compared to the control. With the improvement in nitrate reductase activity, the contents of total protein and carbohydrate also increased significantly at 15% fly ash. The proline content and the total antioxidant activity of beetroot increased significantly with increasing fly ash levels. The elevated levels of proline and antioxidant activity might be responsible for scavenging the oxidative stress caused by the higher concentration of fly ash in the soil. The principal component analysis presented significant correlations among the various considered parameters. Two principal components explained a total of 97.12% overall data variability in plants treated with different levels of fly ash. Therefore, this work suggests that the application of fly ash as a soil amendment is suitable to improve the growth and yield of beetroot.

Variation in the Primary and Secondary Metabolites, Antioxidant and Antibacterial Potentials of Tomatoes, Grown in Soil Blended with Different Concentration of Fly Ash

“…Moreover, soil with high concentration of fly ash (T3 soil) showed impacts on the TPC and TFC of tomatoes, as well as on the various other parameters, such as proximate composition, vitamin C, and mineral contents. All the above results are supported by previous work on beetroot [43] and Jatropha curcas [1]. Fly ash, when used in synergy with soil at sustainable amounts, can prompt the production of beneficial bioactive components.…”

Assessment of mechanisms underlying flyash-mediated control of oxidative stress and antioxidant metabolism in Vicia faba L.

“…It is evident from our results that the scavenging enzymes showed higher accumulation at 50% y ash treatment both at 45 and 90 DAS due to oxidative damage. Plants use their antioxidative mechanism to combat this stress to reduce the production of reactive oxygen species (ROS) generated by metal ions metal(loid)s present in greater concentrations Shakeel et al, 2020;Varshney et al, 2020). Eventually it leads to falsi cation in metabolism of plants at higher y ash concentration (Saeed et al, 2020).…”

Optimizing Nitrogen Application in Root Vegetables from Their Growth, Biochemical and Antioxidant Response to Urea Fertilizer

“…Number of stomata and the ultra-structural dimensions of stomata were determined with the help of scanning electron microscope (SEM) of make JEOL, JSM-6510 LV, Japan. For SEM studies, leaf sample was prepared by following our previous study Shakeel et al [22].…”

“…It ranks among the 10 common potent vegetables concerning its antioxidant property [20]. Being a rich source of antioxidants, minerals, and vitamins, it becomes an efficient supplementary food for humans [21,22]. Considering the nutritional value and health benefits of root crops and the management strategies of N fertilizer, it was planned to evaluate the growth, yield, and biochemical response of these root crops to N fertilizer.…”
