Influence of different modes of pollination (MOP's) viz. without insect pollination (WIP), open pollination (OP) and bee pollination (BP) (with Apis mellifera L. honeybees) on peach (Prunus persica L.) cultivar Flordasun was studied at RRS, Karnal. The pole directions had no affect on the fruit set. In WIP, fruit set was minimum (1.6 fruits/branch), increased phenomenally to 6.2 in OP and was maximum (7.3 fruits/branch) in BP. Thus, resulting in an increase of 287.5 percent in fruit set in OP over WIP and 356.3 per cent in BP over WIP, respectively. In WIP, 35.7 per cent branches bore no fruits at all whereas in BP and OP there were no barren branches. Fruit yield was only 68.2 g per branch in WIP increased to 263.4 g in OP (increase of 286.2%) and was maximum (373.0 g) in BP (increase of 446.9%). The fruits in BP were heaviest at 51.1 g (20.0% heavier than WIP and 20.2% than OP), whereas they were significantly lighter and comparable in OP and WIP (42.5 and 42.6 g/fruit, respectively). In WIP, the fruit dimensions were only 4.0×3.6㎝ that improved significantly in BP to 4.6×4.0㎝ (an increase of 15.0% in length and 11.1 % in breadth). The per plant yields in WIP were only 18.3㎏, increased to 70.8㎏ in OP and were highest in BP at 100.7㎏/plant. The per hectare yields too, were least in WIP (49.78q/㏊) and increased to 194.71 q in OP. Employment of honeybee input (BP) further improved it to 276.93q/㏊, registering an increase of 4.5 times than the WIP. BP significantly increased economic returns to the tune of 5.6 times at Rs. 166,158/㏊ compared to a minuscule Rs. 29,868 in WIP. The economic gains in BP were Rs. 133,290/㏊ over WIP and even Rs. 46,305 over OP at a cost: benefit of 1:44.4.
