Abstract

• Number of cells containing on the colony structures such as open, seal, egg and empty showed very drastic changes. Seal cells were recorded that too highest condition as 33.47% as well as open cells 15.3% in 2Queen beehive 2, respectively. Especially, high condition of seal cells was recorded as 15.23% in Control2. Relation of honey production with mean weather conditions in experiments and control were recorded. Honey production was showed highly statistically significant difference as (p < 0.001) between double-queen and single-queen colonies. Pollen production level was no statistically significant difference as (p > 0.05) for double-queen colonies compared to the singlequeen during the study period. Within each queen systems, production of honey and pollen were recorded statistically significant difference as (p < 0.05), respectively. The large weight honeys were recorded as hive number 1, 2 and 3 of single-queen and double-queen systems during the sunflower seasons. Especially, as 39.8% in hive number 3 was recorded the highest stored honey in singlequeen system and as 37.3% in hive number 2 was recorded the highest weight honey in doublequeen system. Within one queen system as well as two queen system, production of honey and pollen were recorded statistically significant difference as (p < 0.05) with ANOVA HSD test in terms of number of combs occupied by nectar and pollen. Honey production cost difference indicates that was showed higher production costs for managing single-queen colonies compared to double queen colonies as well as pollen production cost
