Abstract:
An field experiment was conducted during kharif season of 2011 and 2012 at S.K.N College of Agriculture, Jobner to study the effect of integrated nutrient management levels on growth parameters and yield of groundnut (Arachis hypogaea L.) Treatments consisted of the eight levels of organic manures and fertilizers in main plots (control, RDF (25kg, N+45kg P2O5 kg ha^-1), FYM 15 t ha^-1, FYM 7.5 t ha^-1+1/2 RDF, Poultry manure 6 t ha^-1, Poultry manure 3 t ha^-1+1/2 RDF, vermicompost 5 t ha-1, and vermicompost 2.5 t ha-1+1/2 RDF) and four levels of iron in sub plots [0.0, 5.0,10.0 and 15.0 kg ha^-1] were compared. Application of poultry manure @ 3 t/ha + ½ RDF was recorded significantly higher nitrogen, phosphorus, potassium and iron content in seed kernel and haulm which being at par with vermicompost. Significantly higher total uptake of nitrogen, phosphorus, potassium and iron was observed with the application of poultry manure @ 3 t/ha + ½ RDF over rest of the treatments except vermicompost @ 2.5 t/ha + ½ RDF. The uptake of nitrogen, phosphorus, potassium and iron by groundnut were increased significantly with the application of 15 kg Fe/ha over control and 5 kg Fe/ha.
