Abstract:

Chromium is a serious heavy metal and it is considered as an environmental hazard. The contamination of the soil environment with chromium compounds is more and more frequently occurring problem throughout the world. Toxicity effects of chromium on growth and development as it decrease the growth and biomass of plant. A pot experiment was conducted in net house of Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2015-16 to study the effect of FYM and vermicompost on growth and yield of rice in chromium contaminated soil. Five levels of chromium viz. 0, 20, 40, 60 and 80 ppm with and without vermicompost @ 5 ton ha-1 and farm yard manure @ 10 ton ha-1 were taken. Results indicated that growth parameters, yield attributes and yield of rice decreased with increasing Cr concentration (0, 20, 40, 60, 80 ppm). The parameters like plant height, number of tillers/hill, productive tillers/hill, chlorophyll content, panicle length, number of grains/panicle, test weight, straw yield, grain yield and harvest index significantly increased with the application of vermicompost and FYM. Rice crop can withstand up to 80 ppm of chromium with vermicompost and can tolerate up to 60 ppm with FYM. Hence, toxic effect of Cr on rice crop may well be mitigated more effectively with vermicompost and FYM application.
