“…Therefore, higher levels of FA adversely affect the growth, yield and pigment content of Indian mustard. Similar results have been observed on several crops such as wheat [8], potato [23] and pumpkin [1]. In the present study, the 30% FA was found best which shows that available nutrients in FA are beneficial at certain levels for utilization of a specific plant species.…”

“…The improvement in chlorophyll content could be due to the presence of Mg in FA, which is the main component of chlorophyll and is required for the structural integrity of chloroplast. The beneficial effect of FA at lower levels (10-30%) has already been observed on many crops such as tomato [15], wheat [8], chickpea [9], potato [23], pumpkin [1].…”

The disposal of fly ash from thermal power plants causes significant economic and environmental problems. Although the fly ash contains several essential minerals, its application in agricultural practices is uncommon in India. The present study was undertaken to elucidate the possibility of fly ash application to agricultural soils to improve growth and yield in Indian mustard. This work was conducted to evaluate the effect of fly ash on growth, yield and chlorophyll content of the Indian mustard (Brassica juncea L.cv. Varuna). For that, a greenhouse experiment was conducted to observe the effect of various fly ash concentrations (0%, 10%, 20%, 30%, 40% and 50% w/w) with normal field soil on plant growth, yield and photosynthetic pigments. The plant growth (length, fresh weight and dry weight of shoot and root; number of leaves and branches per plant), yield (number of pods per plant, number of seeds per pod and weight of 100 seeds per plant) and pigment content (chlorophyll 'a' , chlorophyll 'b' and total chlorophyll) parameters were found to be significantly increased from 10 to 30% fly ash levels being maximum at 30%. However, at higher levels 40% to 50% of fly ash, growth, yield and pigment content parameters were reduced significantly. The perusal of the data revealed that 30% level of fly ash amendment in soil was found to be ideal for better growth, yield and pigment content of Indian mustard.

“…Similarly, y ash (100%)-amended soil signi cantly reduced chlorophyll content (Varshney et al, 2019). Crops such as potato, tomato, wheat and chickpea when amended with 10 to 30% y ash levels showed enhanced photosynthetic activity (Khan and Saboor, 2014;Tomar et al, 2015), which may be associated with improved nutrients availability (Mg, Zn and S).…”

Globally, increasing coal-fired power production has resulted in large accumulations of coal combustion byproducts such as fly ash, widely recognized as a valuable soil ameliorant. Taking into account bakla (Vicia faba L.) in greenhouse experiments, this study aimed to assess the effects of soils amended with fly ash (FA; 0% 5%, 10%, 20%, 30%, 40% and 50%) on the plant growth characteristics and the major photosynthesis variables [(including chlorophyll content; stomatal behavior; activity of carbonic anhydrase (CA), a chloroplast-localized metalloenzyme)]; activity of nitrate reductase (NR), a rate-limiting enzyme of nitrogen metabolism; damage indicators [reactive oxygen species (ROS); and malondialdehyde (MDA), a lipid peroxidation product; and cell viability); and also to evaluate the role of defense characteristics such as proline (a nitrogenous osmolyte), and the major enzymes involved in dismutation of superoxide (superoxide dismutase, SOD); metabolism of H2O2–metabolism (catalase, CAT), and in peroxide-cleaving redox reactions (peroxidase, POX). Measurements were done at 45 days after sowing (DAS). Among the FA-proportions tested, 40 and 50% FA caused significant decreases in plant growth characteristics namely shoot length, root length, plant fresh and dry weight, and leaf area; photosynthesis variables including chlorophyll content, stomatal behavior (aperture size, shape and frequency of stomata); activity of CA and NR, and the viability of cells. These decreases in the mentioned parameters were corroborated with increases in ROS and MDA contents. However, when grown in soils amended with 5%, 10%, 20% and 30% FA, V. faba plants exhibited improvements in the mentioned parameters of growth and photosynthesis, and stomata; and cell viability; which were accompanied with the decreased contents of ROS and MDA, and coordinated increases in the activity of SOD, CAT and POX. Given the protective role of lower concentrations of FA (5%, 10%, 20% and 30%) in V. faba, these FA concentrations may be utilized as a fertilizer in sustainably improving the health and productivity of vegetable crops.
