Effect of salicylic acid on mineral content in Sorghum bicolor (L.) under chromium stress

A study was conducted to determine the efects of salicylic acid on varying Cr (VI) levels [0.0–4.0 mg Cr (VI) kg⁻¹ soil in the form of potassium dichromate] on mineral content of sorghum. Resulta of the investigation revealed that foliar spray and pre-treatment of salicylic acid enhanced the mineral content containing micronutrients (zinc and iron) and macronutrients (sodium and potassium) that were estimated at diferent growth stages, i.e. 35 DAS, 70 DAS and 90 DAS.The application of salicylic acid, in the form of pre-treatment and foliar spray, increased uptake of zinc, iron and potassium and decreased sodium content and other minerals as compared to control treatment under Cr stress.
