Abstract


This research was carried out in 2011 and 2012 in order to determine the flowering phenology, number of flowers, nectar and pollen potential in the Samsun province of the oilseed rape (Brassica napus L.), which is widely used in agriculture in our country. In the first year of the study (2011), it was determined that the rapeseed plant was in flower for 44 days, there were 2.694 flowers per plant, 1.89 kg/da nectar per day and 1330 kg/da pollen production. In the second year of the research (2012), it was revealed that the rapeseed plant was in flower for 39 days, there were 701 plants/flower in the plant, 0.38 kg/da nectar secreted daily and 331.57 kg/da pollen. According to the results of two years, the yield of rapeseed was found to be 41.5 days, the daily nectar production was 0.23 mg/flower/day, the nectar dry matter level was 20.25% and the pollen production was 0.48 mg/flower/day. In Samsun province, it was determined that rapeseed plants flowered before the flowering of many plants in the vicinity in the early spring, and provided honey bees, Apis mellifera L., and many other honey bees, nectar and pollen. It has been demonstrated that the cultivation of rapeseed is cultivated in the early spring, and it can be a convenient source of food for honey bees and other dusty insects.
