Abstract:

An attempt was initiated during two consecutive kharif seasons during 2015-16 and 2016-17 at the farm of the Tamil Nadu Agricultural University, Coimbatore to ascertain the response of plant density and nutrient management on hybrid sunflower (Helianthus annuus L.). The experiment comprised eleven treatments viz., 60 x 30 cm with single seedling and 100% RDF (T1), 60 x 30 cm with two seedling per hill and 150% RDF (T2), 60 x 30 cm with two seedling per hill and 200% RDF (T3), 60 x 45 cm with two seedlings per hill and 125% RDF (T4), 60 x 45 cm with two seedlings per hill and 150% RDF (T5), 45 x 45 cm with two seedling and 150% RDF (T6), 45 x 45 cm with two seedling with 200% RDF (T7), 45 x 30 cm with single seedling and 125% RDF (T8), 45 x 30 cm single seedling and 150% RDF (T9), 30 x 30 cm with single seedling and 150% RDF (T10), 30 x 30 cm with single seedling and 200% RDF (T11). The sowing density of 30 x 30 cm with single seedling and 200% had accumulated the highest amount of DMP 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 60 x 30 cm with single seedling and 100% RDF. The seed yield significantly higher by adoption of 30 x 30 cm with single seedling and application of 200% RDF. (Key words: Dry matter production, Head diameter, number of seeds per head, seed volume weight)
