The plants were grown in plastic pots with four level of chromium concentration [control (0.0, 1.0 mg Cr (VI) kg -1 soil,2.0 mg Cr (VI) kg -1 soiland 4.0mg Cr (VI) kg -1 soil).To ameliorate the toxic effect of Cr (VI) given different treatments of salicylic acid and ferrous sulphate viz. pre-treatment, soil treatment and foliar spray or both. Morphological parameters like plant height, number of leaves, root length, fresh and dry weight of leaves, stem and root decreased with an increasein the chromium concentration. The chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll content decreased whereas, structural carbohydrates viz. NDF, ADF, cellulose, lignin and silica significantly increased with increasing chromium concentration. Nonstructural carbohydrate (total sugars, reducing sugars and non-reducing sugars), crude protein content and IVDMD decreased with an increase in chromium concentration. Minerals like sodium, chromium and zinc content increased with increase in chromium concentration. The iron and potassium content decreased with increase in chromium concentration. Growth of sorghum plant was reduced very significantly in excess chromium. This loss in growth of sorghum plant was recovered partially by different treatments by salicylic acid (0.5 mM) andFeSO 4-EDTA solution (0.25 mM and 0.5 mM). The recovery in biomass of sorghum was maximum when FeSO4-EDTA solution was applied through both the ways i.e. through roots and through foliar spray together.enHeavy metal stress, Morphological parameters, Biochemical parameters, Nutritive valueThesis
