Effect of Compost and Fertilizers on Growth of <I>Albizia procera</I> in Coal Mine overburden

Abstract

The effect of different combinations of Soil and Compost as well as different sources of nitrogen on growth of Albizia procera in coal mine overburden ofTalcher, Orissa was studied. Results obtained indicated that, for different nitrogenous fertilizers applied @ 150 ppm with basal dose of 25 ppm P₂0₅ and 100 ppm K₂0 Albizia procera showed better response to ammonium sulphate as compared to control. However, number of nodules was maximum in ammonium chloride treated sample, while root was longest in control. In another experiment, best growth performance of the species was recorded in treatment receiving 1 : 2 soil-compost mixture (v/v) followed by 1 : 1 and 1 : 0.5 soil-compost mixture and control.
