Self-pollinated Sarson plants (covered with muslin netting) produced 26.46to 34.34 (mean 28.68) grams of seed per plant while honey bee pollinated and non-apis insect pollinated plants yielded 67.2 to 90.02 (mean 74.37) grams and 41,72 to 56.35 (mean 48.42) grams per plant, respectively. The increase in seed yield due to insect pollination was 159.31% in case of honey bee pollinated plants and 68.83% in min-apis insect pollinated plants. Besides producing increase yield insect pollination caused formation of well-shapped, larger grains and more viable seed than the self pollinated plants.
