Abstract

Because of industrialization and urbanization, there is no much land is available for urban farming in and around Mumbai. Wherever the small lands are available as open space, unused lands, barren lands etc are contaminated by heavy metals which come through industrial waste disposal. Such lands can be mycoremediated by use of mycorrhizal fungi to a certain extent and can be utilized for urban farming of leafy vegetables. Present investigation was carried out in the form of pot experiment to check the response of Glomus mosseae to Trigonell foenum-graceum which was grown in soil contaminated with heavy metal Arsenic. During these experiments, soils with different concentrations of arsenic with and without mycorrhizal inoculums were tested in Trigonella foenum – graceum. The response of mycorrhiza in T. foenum-graceum was determined in terms of percentage germination of seeds, sustainability of seedlings, fresh weight and dry weight of plants etc. It was observed that in the pot with soil contaminated with arsenic and no mycorrhizal inoculum, performance was very bad in terms of all aspects of growth, whereas in the pot where mycorrhizal inoculum was added along with contaminated soil, the performance of the plant was better. The pot showing no contaminated soil with arsenic but the inoculum of mycorrhiza was showing best results in terms of percentage germination of seeds, sustainability of seedlings, fresh weight and dry weight of plants.
