Bhuiyan M.S., Mondol M.R.I., Rahaman M.A., Alam M.S. and Faisal A.H.M.A. 2008. Yield and Yield Attributes of Rapeseed as Influenced by Date of Planting. Int. J. Sustain. Crop Prod. 3(3):25-29 An experiment was conducted at the Agriculture Research Station, Bangladesh Agricultural Research Institute, Burirhat, Rangpur during rabi season of 2004-05 to find out optimum planting time for the newly selected genotype BCYS-03. There were five planting dates viz. October 20, October 30, November 10, November 20 and November 30. Significant variations due to different planting dates were observed in days to flowering, days to maturity, plant height, number of primary branches plant, siliqua plant, seeds siliqua, 1000-seed weight, seed yield plant, stover yield haand seed yield ha. Results showed that the highest seed yield (1.86 t ha) was obtained from the second planting (October 30) and it was significantly different from the yields of all other dates of planting. All other yield attributes were also found higher in the plants of second planting. The seed yield (1.47 t ha) of last planting (November 30) was also satisfactory because of the prolong winter season prevails in the northern part of the country.
