Influence of yellow gypsum on nutrient uptake and yield of groundnut in different acid soils of Southern India

Abstract: Yellow gypsum (YG), a synthetic product from Linz-Donawitz slag containing high iron (Fe) (5.41%), zinc (Zn) (0.37%) and silicon (Si) (3.41%) can be used as a source of these nutrients along with calcium (Ca) and sulphur (S) for groundnut production. Three field experiments were conducted to know the effect of different rates (500 and 625 kg YG ha−1) and time of application (basal alone and basal + split) of YG on growth, yield and economic returns of groundnut, and micronutrient and Si availability and their … Show more

“…The rapeseed plants were dried in the hot air oven at 70ºC and then microwave digestion of samples was performed. Prior to microwave digestion, the samples were subjected for pre digestion by adding 7 ml of 70% nitric acid, 2 ml of 30% hydrogen peroxide and 1 ml of 40% hydrofluoric acid (Laxmanarayanan et al, 2022). The Si content was estimated using the molybdenum blue colorimetric method at 600 nm (Ma et al, 2001).…”

“…The synthesis of DG helped to achieve a major objective in environmental sustainability of steel production by presenting a route for the synthesis of a value-added product (synthetic gypsum) from LD slag, which is an industrial waste product of the steel industry [17,25]. This is an important development and a step forward for generating wealth from waste.…”
