Effect of briquetting and carbonisation plant effluent on seed germination of five varieties of groundnut (Arachis hypogaea L.)

Abstract

                     The study deals with pollution by Briquetting and Carbonization plant effluent and its effect on five varieties of groundnut to evaluate its irrigation potential.  The effluent is brownish black in colour. It contains higher amount of total nitrogen, metallic and non-metallic ions, sulphates, sodium, chloride, calcium and magnesium.  The impact of various concentrations (10, 25, 50, 75 and 100 per cent) of this effluent on the seedling growth of five varieties of groundnut (Arachis hypogaea L.) was studied under laboratory conditions.  Germination percentage, seedling growth, fresh weight and dry weight of groundnut seedlings exhibited a gradual increase upto 10 per cent and decrease at higher concentrations.  The variety VRI-4 showed the better growth performance than the other varieties studied under effluent treatment.
