The study was carried out to investigate the row spacing effects on the growth and yield of sunflower cultivars at Oil Seeds Section, Agriculture Research Institute, Quetta during Kharif season 2010. The responses of three sunflower cultivars to row spacing was analysed in terms of different growth and yield components. Sunflower cultivars (Hysun-33, NK-S-278 and Parsun-II) were cropped at 55, 75 and 95 cm row spacing, and the plant to plant distance was kept constant at 30cm. The experiment was conducted using RCB Design ...

The study was carried out to investigate the row spacing effects on the growth and yield of sunflower cultivars at Oil Seeds Section, Agriculture Research Institute, Quetta during Kharif season 2010. The responses of three sunflower cultivars to row spacing was analysed in terms of different growth and yield components. Sunflower cultivars (Hysun-33, NK-S-278 and Parsun-II) were cropped at 55, 75 and 95 cm row spacing, and the plant to plant distance was kept constant at 30cm. The experiment was conducted using RCB Design (factorial) with four replication. In this research study the sunflower hybrid Hysun-33 show early flower initiation (59.25 days) followed by Parsun-II (60.5 days) with optimum row spacing of 75cm. Hysun-33 exhibit early flower completion (65 days) with optimum row spacing of 75cm, followed by the same Hybrid (66.25 days) with narrow row spacing of 55cm. Hysun-33 and NK-S-278 reveal early maturity (97 days each) with narrow row spacing of 55cm. The taller plants (178 cm) was observed in Hysun-33 with optimum row spacing of 75cm followed by the same hybrid (177.5 cm) with narrow row spacing of 55 cm.
