Studies were conducted during rabi 2011-12 and 2012-13 at ARS, Kota on coriander crop to determine the effect of pollinators in quantitative yield parameters. Coriander variety "CS-6" was grown following all recommended agronomic practices. The plots were kept unsprayed throughout the crop season. The colonies of honeybee (Apis mellifera) were placed in hives before the initiation of flowering. The present study contained three pollination treatments viz., Plants caged Pollinator exclusion (PE), Plants caged with bee hive (BP) and Plants kept open to all pollinators ( OP). The comperative data pertaining to modes of pollination in coriander crop revealed that difference in mean seeds per plant, per cent seed set, and seed yield (Q/ha) were statistically significant. The highest values of mean seed/ plant (288.35), seed set (77.25%) and seed yield (13.58 q/ha) were obtained from open pollinated followed by bee pollinated and it was recorded lowest in pollinator exclude.
