Abstract:

In order to quantify the response of honeybee on canola seed yield, an experiment was conducted at National Agriculture Research Center, Islamabad, during 2007-08, in complete randomized block design with two treatments (i. Plants caged with honeybees ii. Plants caged without honeybees) with four replications each. Number of pods set, pods weight, seed count in hundred pods and yield per plant were measured in twenty randomly harvested plants. The results showed significant increase in all the plant parameters caged with bees as compared to the plants without bees (control). Number of pods and number of seeds pod-1 with pollination were 815 and 20 while without pollination was 349 and 15. The seed weight and yield (gm) with pollination was 26 and 7.6 (gm) and without pollination was 9.3 and 1.51 (gm), respectively. It is concluded from the experiment that honeybee visitation to the canola flowers is important for pollination and increasing seed yield.
