An experiment was conducted at College of Horticulture, GKVK campus, Bengaluru, UHS, Bagalkot to study the vegetative parameters with different agrotechniques in ornamental sunflower. Plant height was highest with   162.43 cm. For ornamental crops minimum plant height with optimum quality of flowers is preferred. The treatment combination of M1 (with mulch) + S1 (60 cm x 40 cm) + F3 (80:90:80 NPK kg ha-1) recorded highest plant spread 4642.97 cm2. M1 (with mulch) + S1 (60 cm x 40 cm) + F1 (40:60:40 NPK kg ha-1), produced highest number of leaves (26.93). Maximum leaf area 5328.23 cm2was with M1 (with mulch) + S2 (60 cm x 30 cm) + F3 (80:90:80 NPK kg ha-1). From the present investigation for better vegetative growth mulching can be followed with lower to higher spacing with higher fertilizer dose. But as higher fertilizer dose and mulching will increase the cost of cultivation for this short duration crop optimum agrotechniques to be followed would be M2 (without mulch) + S2 (60 cm x 30 cm) + F2 (60:75:60 NPK kg ha-1).
