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+1/2 RDF was recorded significantly higher dry matter accumulation, branches per plant, pod yield and stover yield of groundnut over rest of the treatments during both the years of study. Iron levels up to 10 kg/ha also significantly increased the dry matter accumulation, branches per plant, Leaf Area Index (LAI), chlorophyll content, dry weight of nodules pod and stover yield of groundnut over control upto 10 kg Fe/ha but was found at par with 15 kg Fe/ha during both the years of study as well as on pooled basis.
