Abstract
Presently, the crisis of enormous amounts of fly ash has been sorted out by using it significantly in stabilization and escalating crop growth. In present study pot-culture experiment was performed to observe the influence of fly ash amendments on the growth and accretion of heavy metal in pea plants. Fly ash utilized for this study with high alkalinity and metals was poor in N, P and humus comparable to garden soil. Fly ash and soil were mixed in different ratios i.e. 0, 5, 10, 15, 20 and 25% and used to fill earthen pots (2Kg/pot). Seven days old seedlings were transplanted (3 individual/ pot) in them at glass house. 25±2 0 C temperature and moisture at 50% of water holding capacity was maintained throughout the experiment. The results revealed that there was a significant increase in chlorophyll, carotenoids, proteins, biomass and overall growth of target plant up to 10% fly ash amendment. Whereas, phenols and ascorbic acid concentrations were maximum at 25% fly ash amendment. The heavy metals in growth media and plant were significantly augmented and found beneath the permissible limits up to 10% fly ash addition only. Pea seeds demonstrated fascinating results they were harboring the metal concentration in all amendments under permissible range and were safe to consume. Translocation factor was calculated and results illustrated that toxic heavy metals like Cd, Ni and Pb retained in the below ground while micronutrients like Cu, Zn and Fe translocated to above ground parts. Hence, it is evident that pea plants may be a good metal accumulator plant species that could use for restoration of waste land having high alkalinity and low nutrient values.
