Abstract: The use of metallurgical solid wastes such as steel slag in agricultural activity, has become very important to contribute to reducing the accumulation of such wastes in the environment and to increase crop production. The use of steel slag in agriculture produces not only economic but also ecological advantages. The Vigna radiata alternately known as the green gram and it is a plant species belongs to family Fabaceae. It is very important pulse which is consumed all over the world. It has the source of protein, fiber, minerals, vitamins, etc. It can be cultivated on a very wide range of soil. For the best result, when grown on well drained loamy soils are not suitable for cultivation. Rourkela is an industrial area and there is growing concern in the air pollution. Rourkela Steel Plant generates waste slag in huge amount for about 772,476 tonnes per year. it is considered as an environmental problem. It can have adverse effect impacts on crops on their growth stage. The present work is to study the root nodule formation in different concentration of slag treatment resulted variable impact in the root nodule formation but it is insignificant.
