An experiment was conducted to determine the effect
\r\nof pollination on seed quality of rapeseed in Chitwan, Nepal during
\r\n2012-2013. The experiment was designed in Randomized Complete
\r\nBlock with four replications and five treatments. The rapeseed plots
\r\nwere caged with mosquito nets at 10% flowering except natural
\r\npollination. Two-framed colonies of Apis mellifera L. and Apis
\r\ncerana F. were introduced separately for pollination, and control plot
\r\ncaged without pollinators. The highest germination percent was
\r\nobserved on Apis cerana F. pollinated plot seeds (90.50%
\r\ngermination) followed by Apis mellifera L. pollinated plots (87.25 %)
\r\nand lowest on control plots (42.00% germination) seeds. Similarly,
\r\nseed test weight of Apis cerana F. pollinated plots (3.22 gm\/ 1000
\r\nseed) and Apis mellifera L. pollinated plots (2.93 gm\/1000 seed) were
\r\nand lowest on control plots (2.26 gm\/ 1000 seed) recorded. Likewise,
\r\noil content was recorded highest on pollinated by Apis cerana F.
\r\n(36.1%) followed by pollinated by Apis mellifera L. (35.4%) and
\r\nlowest on control plots (32.8%). This study clearly indicated
\r\npollination increases the seed quality of rapeseed and therefore,
\r\nmanagement of honeybee is necessary for producing higher quality of
\r\nrapeseed under Chitwan condition.<\/p>\r\n","references":"[1] MoAC, \u2018Statistical information on Nepalese agriculture.\u2019 Government of\r\nNepal Ministry of Agriculture and Co-operatives Agri-Business\r\nPromotion and Statistics Division Singha Durbar, Kathmandu.
