Enhancing Wheat (Triticum aestivum L.) Resilience to Hexavalent Chromium Stress through the Application of Farmyard Manure

Abstract

Toxicity due to heavy metals is one of leading contributors of losses in crop fields in the whole world. In the current research work, the impact of organic soil amendment with farmyard manure on different growth and physiological parameters of wheat plants under the stress of Hexavalent Chromium (Cr-VI) was investigated. The experiment was conducted in plastic pots in the greenhouse. In the experiment, three different treatments concentrations of Cr(VI) (100, 200 and 300 mg kg^-1) were taken individually and in combination with 1% FYM. Wheat grown under the stresses of chromium exhibited the reduction in growth parameters like shoot length, root length, root biomass and shoot biomass. Whereas, the soil amendment with 1% farmyard manure metigated the effect of both stresses and enhanced the growth of tested plant. Thus, soil amendment with farmyard manure reduced the chromium stress in plants. So far, further studies are required to investigate the efficacy of farmyard manure as a soil amendment in abiotic stresses in soil to enhance the plant growth in field trials.
