This research was investigated to assess the effect of fly ash (FA) on the growth, yield, biochemical attributes, and enzymatic antioxidant response of chickpea (Cicer arietinum L. cv. Avrodhi). After evaluating soil and FA nutrient status by energy-dispersive X-ray spectroscopy (EDX), different concentrations of FA with soil were applied (5, 10, 15, 20, 25, and 30%). Chickpea plants grown at all FA-amended soil concentrations demonstrate significant improvement (p ≤ 0.05) in growth and yield biomass. Exhibition of enhancement in biochemical attributes such as photosynthetic pigments (chlorophyll a and b, total chlorophyll, and total carotenoid by 16.83, 24.50, 19.13, and 21.74%), total protein (48.54%), leghemoglobin (42.39%), nitrate reductase activity (18.35%), proline content (28.16%), and antioxidant enzymes activities. Moreover, an improvement in the stomatal pore of the FA treated plant also noticed by a scanning electron microscope (SEM). Overall, the findings of this study indicate that the supplementation of FA contributed to increment in these attributes at all the concentrations compared with control (without FA) ‘but maximally ~ up to FA 20%.’ However, plant growth and yield biomass decreased above the concentration of FA 20% because chickpea can balanced nutrients efficiency up to FA 20%.

对该研究进行了调查，以评估粉煤灰（FA）对鹰嘴豆（Cicer arietinum  L. cv。Avrodhi）的生长，产量，生化特性和酶促抗氧化反应的影响。在通过能量色散X射线光谱法（EDX）评估土壤和FA养分状况后，对土壤施用了不同浓度的FA（5％，10％，15％，20％，25％和30％）。在所有经过FA校正的土壤浓度下生长的鹰嘴豆植物均表现出显着的改善（p ≤0.05）的生长量并产生生物量。光化学色素（叶绿素a和b，总叶绿素和总类胡萝卜素分别增加16.83、24.50、19.13和21.74％），总蛋白（48.54％），豆血红蛋白（42.39％），硝酸还原酶活性等生化属性的提高（18.35％），脯氨酸含量（28.16％）和抗氧化酶活性。此外，通过扫描电子显微镜（SEM）也注意到FA处理过的植物的气孔孔的改善。总的来说，这项研究的结果表明，与对照相比（不含FA），在所有浓度下，FA的添加都有助于这些属性的增加，“但最大〜20％”。但是，由于鹰嘴豆可以平衡高达20％FA的养分效率，因此植物的生长和单产生物量下降到FA 20％以上的浓度。
