Abstract
The field experiments were conducted at Eastern Block farm of Tamil Nadu Agricultural University during rabi season of 2015 and 2016, to study the effect of different sowing density and nutrient management on growth, yield and nutrient uptake of sunflower (Helianthus annuus L.). The experiment was laid out in a randomized block design with eleven treatment combinations and replicated thrice. The soil of the experimental field was silty clay loam in texture, low in available nitrogen, medium in available phosphorus and high in available potassium content. The sowing density of 30 x 30 cm with single seedling and 200% had accumulated the highest amount of DMP (10987 and 12070 kg ha-1 during rabi season of 2015 and 2016 respectively) which was 15% higher than the lower sowing density of 60 x 30 cm. The yield parameters like head diameter (cm), number of seeds per head, head weight, seed weight and seed volume weight were higher under the sowing density of 60x30 cm with single seedling and 100% RDF. The seed yield significantly higher by adoption of 30x30 cm with single seedling and application of 200% RDF.
