A field study was conducted during Kharif 2012 and 2013 at Krishi Vigyana Kendra, Janwada, Bidar, University of Agricultural Sciences, Raichur, Karnataka, India to study the effect of crop residues on chemical properties of soil and nutrient uptake of soybean in rainfed situation of Northern Karnataka. Results revealed that, application of RDF (40:80:25 NPK kg/ha + 12 kg ZnSO4/ha+ 20 kg sulphur/ha) + plant residues at 3.0 tonnes/ha recorded significantly (p=0.05) higher uptake of nitrogen (225.7 kg/ha), phosphorus (17.0 kg/ha) and potassium (73.5 kg/ha) by soybean and which was onpar with the application of RDF + plant residues at 2.25 tonnes/ha (157.8, 16.3 and 71.3 kg/ha, respectively). Further, Application of RDF + plant residues at 0.75, 1.5 and 2.25 tonnes/ha were atpar with each other with respect to nitrogen, phosphorus and potassium uptake by the soybean. Application of RDF (40:80:25 NPK kg/ha + 12 kg ZnSO4/ha+ 20 kg sulphur/ha) + plant residues at 3.0 tonnes/ha has been increased the soil available nutrients and improves the soil fertility.
