Abstract

In order to study the effects of different sowing dates and plant densities on some growth traits of Anise (Pimpinella anisum L. ), a field experiment was done at Agricultural College of Shahid Chamran University in 2016. Experimental design set as a split plot on Randomized Complete Block Design with three replications. Main plot was sowing dates in three levels (11Nov, 28 Nov and 11 Dec) and sub plot was different plant densities at three levels included: (30, 40 and 50 plant/m2). The result showed that sowing date, plant densities and interactions had significant effect on most under study traits. The highest plant height (86. 08 cm), leaf area (0. 124 m2), number of umbel per plant (6. 20), lateral umbel/plant (150. 21), grain yield (678. 29 kg/ha), essential oil yield (13. 64 kg/ha), and harvest index (10. 05%) were obtained at 28 Nov sowing date and the highest biological yield (6812 kg/ha) was observed at 11 Nov. Late sowing caused to decrease all traits except 1000 seeds weight, whereas the highest 1000 seeds weight (1. 23 gr) was obtained at 11 Dec. plant density had also significant effect on all traits in which the highest plant height (83. 95 cm), leaf area (0. 119 m2), umbel number/plant (6. 38), lateral umbel/plant (151. 14), grain yield (724. 94 kg/ha), essential oil yield (14. 32 kg/ha), and harvest index (10. 71%) were revealed at 40 plant/m2 density and the highest 1000 seeds weight(1. 118 gr) and biological yield (6786. 66 kg/ha) were observed at 50 plant/m2 density. The lowest values were revealed at 30 plant/m2 densities. Overall, the highest grain yield (859. 87 kg/ha) and essential oil yield (19. 91 kg/ha) were obtained at 28 Nov and 40 plant/m2 and the lowest grain yield (388. 28 kg/ha) and essential oil yield (3. 49 kg/ha) were observed at 11 Dec and 30 plant/m2.
