Abstract

Groundnut is referred as king of oil seeds. It is a low annual herb. This is a legumes crop which is mainly cultivated for its edible seeds. Tannery industries are one of the oldest and the major industries in our country. A tannery effluents characteristics in India indicates that the pollutant are of high BOD, COD, sulfide, chromium, suspended particulate matter and salt concentration. Varietal screening experiment was conducted on five varieties of groundnut (JL24, TAG24, TMV7, TMV24, TG37A and TMV-13) treated with different concentration of tannery effluent taking cognizance of the parameter such as germination percentage, root length and shoot length. All these parameters were found to be at an increasing trends on 20% concentration of the effluent contrasting sharply with the situation in higher concentration and this work helps in conversation of tannery waste to a fertilizer which can helps in reduction of environmental pollution.

Keywords: BOD, COD, sulfide, chromium.
