Four varieties of Onion viz., Phulkara, Dark Red, Desi and Rubina were evaluated to see the effect of pollinator on seed setting. Reduced or limited visiting of pollinators caused substantial reduction in seed production of onion showing 50 to 61% seed setting with non significant differences among the varieties. However, significant differences were observed among varieties for number of flowers, fertilized flowers, seed weight per umbel and umbel weight. This reduction in seed production could be due to pesticides application or attraction of side grown crops (Sunflower, Brassica and Coriander etc.)
