Abstract
Studies on the pollination efficiency of honey bees in sunflower (Helianthus annuus L.) revealed that the seeds/ capitulam (1278), 1000 seeds weight (47.3), and % crinkled seeds (8.2) were maximum in six framed Apis mellifera pollinated crop followed by one colony of Apis florea pollinated crop. The six framed Apis mellifera yield in (16.4q /ha^-1), one colony of Apis florea (15.0 q /ha^-1), and% seed setting in Apis mellifera (86.9%) crop was significantly higher over the pollination without insects. Although six framed Apis mellifera pollinated crop was statistically at par with one colony of Apis florae pollinated crop but the % of germination was significantly in higher six framed Apis mellifera (94.3%) followed by open pollination (93.5%)
