Abstract:
Macrophomina phaseolina Goid. is a soil borne pathogen that causes charcoal rot disease in various plants. More than 500 plant species have been reported that are affected by this fungus. This is a ubiquitous fungus and produce microsclerotia, pycnidia, condia hyphae in soil. The previous studies done by plant pathologist showed that number of sclerotia of M. phasolina was also found in the contaminated soil with different heavy metals such as copper, zinc, cobalt etc. In the current research work, the impact of organic soil amendment with farmyard manure on different growth and physiological parameters of mash bean plant under the individual as well as collective stress of Macrophomina phaseolina and Cr(VI) was investigated. An experiment with 16 different treatments was conducted in pots. These different treatments included negative control, positive control, Cr (VI) 100 and 200mg kg-1, 1 and 2% FYM and M. phaseolina in different combinations. Mash bean plant grown under the stresses of chromium and charcoal rot pathogen i.e., M. pahseolina (individually as well as combined stress) exhibited the reduction in growth parameters like shoot length, root length, root biomass and shoot biomass. Whereas, the soil amendment with farmyard manure nullifies the effect of both stresses and enhance the growth of tested plant. Thus, soil amendment with farmyard manure reduced both biotic and abiotic stresses in soil. So far, further studies are required to investigate the efficacy of farmyard manure as a soil amendment in biotic and abiotic stresses in soil to enhance the plant growth in field trials.
