Effect of Pollinators and Insecticides on Seed Reduction of Onion (Allium cepa L.)

Saeed Ahmad, Taj Muhammad, Abdul Karim, Abdul Jabbar and Ghayour Ahmad
Four varieties of onion viz; Phulkara Dark Red, Desi and Rubina were evaluated to see the effect of pollinator and insecticides 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 difference among the varieties. However significant differences were observed among varieties for number of flowers per umbel, number of fertilized flowers per umbel, umbel weight and seed weight per umbel. This reduction in seed production could be due to pesticides application of side grown crops (sunflower, brassica and coriander etc.).
