Abstract

A field experiment was conducted at Agricultural Research Station, Annigeri, University of Agricultural Sciences, Dharwad during rabi season of 2015-16 under rainfed condition to study the effect of integrated nutrient management (INM) practices on nutrients uptake by safflower and nutrients status in Vertisol Soil in safflower crop. Results indicated that among the different INM combinations tested, application of RDF (40:40:12 kg ha-1 NPK) + 2.0 t ha-1 Vermicompost + Azospirillum + PSB + ZnSO4@ 10.0 kg ha-1 (T10) recorded significantly highest nutrient content and uptake of nitrogen (33.75 and 36.70 Kg ha-1) phosphorus (8.72 and 15.67 Kg ha-1) and potassium (20.72 and 34.97 Kg ha-1) at 60 DAS and at harvest respectively. The available nutrients content of N, P2O5 and K2O in soil at harvest were also recorded significantly higher in treatment T10 (application of RDF (40:40:12 kg ha-1 NPK) + 2.0 t ha-1 Vermicompost + Azospirillum + PSB + ZnSO4@ 10.0 kg ha-1).
