Abstract: A field experiment was conducted during the year 2013 to study the effect of nutrient management practices on growth and yield of hybrid sunflower (cv. RSFH 130) in split plot design on medium deep black soil under protective irrigation at Agricultural Research Station, Hagari, Ballari, University of Agricultural Sciences, Raichur, Karnataka. Treatments consisted of four main plot treatments; different nutrient management practices through soil application viz., M1; application of RDF ( 90:90:60 kg N, P2O5, K2O /ha), M2; application of RDF + FYM @ 8 t/ha, M3; application of 85 % RDF + FYM @ 8 t/ha and M4; application of 60 % RDF + FYM @ 8 t/ha and four sub plot treatments; nutrient management practices through water soluble foliar grade fertilizers viz., S1; control, S2; foliar application of 19:19:19 water soluble foliar grade fertilizer @ 2% at 25 and 40 DAS, S3; foliar application of 17:44 water soluble foliar grade fertilizer @ 2% at 25 and 40 DAS and S4; foliar application of urea @ 2% at 25 and 40 DAS. Results revealed that application of RDF + FYM @ 8 t/ha along with foliar application of 19:19:19 water soluble foliar grade fertilizer @ 2% at 25 and 40 DAS recorded higher plant height, stem girth, total dry matter production, head diameter, seed yield per plant, thousand seed weight, seed yield, stalk yield, oil content and oil yield of sunflower when compared to other treatment combinations.
