Abstract: Significant differences in different modes of pollination on fennel were found during two consecutive years. The mean number of flowers/umbel were recorded maximum in open to all insect pollinators i.e 272.30 and 265.40, respectively during the mentioned year, followed by crop caged with Apis mellifera (244.70 & 227.90). The number of filled seeds/umbel were recorded significantly higher in open to all insect pollinators (209.66 & 192.73) followed by Apis mellifera pollinated crop (171.40, 157.25). The per cent seed set was maximum (76.99 & 72.61) in open to all insect pollinators whereas Apis mellifera pollinated crop showed significantly higher (70.04 & 69.00) seed setting as compared to self-pollinated crop (55.52 & 48.75). The 1000-seeds weights were significantly higher in open to all insect pollinators (6.50 & 6.30 g) in comparison to Apis mellifera pollinated crop (5.90 & 5.80 g). The seed yield obtained from open to all insect pollinators was highest (13.75 & 12.80 q/ha) while the plots with Apis mellifera was (12.90 & 11.50 q/ha), statistically higher than self-pollinated crop (8.80 & 7.90 q/ha). The maximum germination (84.00 & 82.50) per cent was recorded in open to all insect pollinators followed by Apis mellifera pollinated crop (79.50 & 77.25) per cent whereas minimum was recorded in self-pollinated crop (57.75 & 55.50) per cent in the mentioned year, respectively.
