Abstract
Background: Sulphur (S) is an essential macronutrient required for growth and development of plants. This study was carried out to investigate the effect of Bio Sulphur Granules (BSG) developed with elemental sulphur and sulphur oxidizing bacteria (SOB) on the antioxidative defense system in blackgram under sulphur deficient calcareous soil. Methods: Bio Sulphur Granule (BSG) was developed using ES plus SOB and its efficacy was tested in a pot experiment with blackgram as a test crop from April to June 2022. Plant samples were collected and analyzed in the laboratory for anti-oxidant status of blackgram, how sulphate stress affects the physiological and metabolic processes of plants, which in- turn affects crop yield. Results: Photo assimilatory pigments were decreased and carbohydrates (sugar and starch) were accumulated in leaves of no sulphur treated plants. Hydrogen peroxide in without S supplied plant caused oxidative damage in plants, which also evident by the increase in activity of super oxide dismutase, catalase, peroxidase and ascorbate. The findings showed that by applying S as BSG granules (ES @ 40 kg S ha-1 + Methylobacterium thiocyanatum VRI7-A4) to S-deficient calcareous vertisols might prevent the oxidative damage of plant cells there by improve the growth of blackgram by S-oxidation.
