A field experiment was conducted at College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar on sandy loam soils during summer season of 2018-19 with an objective of evaluating nutrient management for enhancing sunflower productivity (Helianthus annuus L.) under eastern Indian conditions. The experiment was laid out in a randomized block design with three replications. There were twelve treatment combinations viz., Control, RDF (60:80:60 kg N: P2O5: K2O/ha), RDF + S @ 40 kg/ha,RDF + B @ 0.02% ,RDF + S @ 40 kg/ha + B @ 0.02%,STBFR (60:100:60 kg N: P2O5: K2O/ha + S @ 40 kg/ha + B @ 0.02%) , FYM @ 5 t/ha ,RDF + FYM @ 5 t/ha, RDF + FYM @ 5 t/ha + S @ 40 kg/ha , RDF + FYM @ 5 t/ha + B @ 0.02% , RDF + FYM @ 5 t/ha + S @ 40 kg/ha + B @ 0.02%, STBFR + FYM @ 5 t/ha. The results of the study indicated that integrated nutrient management exhibited significant effect on growth, seed and oil yield of sunflower. Application of STBFR + FYM @ 5 t/ha recorded significantly highest growth parameters, seed(2.59 t/ha) and oil yield(1114 kg/ha) of sunflower which remained at par with RDF + FYM @ 5 t/ha + S @ 40 kg/ha + B @ 0.02%.
