Abstract

Rapeseed is an important cash crop of Nepal and an experiment was conducted to study the effect of pollination on its production in Chitwan during 2012-2013. The experiment was designed in Randomized Complete Block with four replications and five pollination treatments. The rapeseed plots were caged with mosquito nets at 10% flowering except natural pollination. Two-framed colonies of Apis mellifera L. and Apis cerana F. were introduced separately for pollination, and control plot caged without pollinators. Seed set increased by 48.72% with Apis cerana F. and 45.73% with Apis mellifera L. pollination as compared to the control. The highest seed yield was obtained from Apis cerana F. (1.11 mt/ha), followed by Apis mellifera L. (0.88 mt/ha), hand (0.75 mt/ha), natural pollination (0.66 mt/ha) and control (0.13 mt/ha), respectively. This study clearly indicated pollination deficit under natural condition, and therefore, management of honeybee is necessary for higher production and productivity of rapeseed under Chitwan condition.
