A field experiment was conducted at the Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore, to know the effect of Site Specific Nutrient Management (SSNM) on growth (plant height (cm), Leaf area (cm2 ), leaf area index (LAI) and dry matter production (g plant1 ) and yield (capitulum diameter (cm), No. of filled seeds, 1000 seed weight (g) and seed yield (kg ha-1 ) of hybrid sunflower seed production. The study indicated that significantly higher growth parameters viz., plant height (155.4 cm), leaf area (1293.10cm-2 ), leaf area index (0.69) and total dry matter accumulation (88.16 g plant-1 ) were recorded with SSNM for 1.2 tons ha-1 + Farm Yard Manure (FYM) as compared to recommended practice (Recommended Dose of Fertilizer 62.50:75:62.50 kg NPK ha-1 ). The application of fertilizers based on SSNM for a target yield of 1.2 t ha-1 + FYM resulted in significantly higher yield and yield attributes compared to the only application of RDF + FYM. The important yield parameters recorded that were significantly higher were viz., head diameter (19.89 cm) number of filled seeds per head (353.24), seed weight per plant (19.76 g), 1000 seed weight (43.72 g), hybrid seed yield (1003 kg ha-1 ).
