Abstract:
An experiment was carried out at the Agronomy Field Laboratory, her-e
Bangla Agricultural University Dhaka, during the period from November
20,07 to February 2008 to study the effect of row spacing on the yield and
yield contributing characters of rapeseed. Four high yielding varieties of
rapeseed (viz. Improved Tori 7, SAU Sharisa l, BARI Sharisa 9 BARI
Sharisa 13) and three row spacings (viz. 15 30 and 45 cm were included as
experimental treatments. The experiment was laid out in a two factor
randomized completely block design with three replications. The spacing
between plants in a row was maintained at 5 cm distance. Result showed that
BARl Sharisa 9 produced the highest yield of 1.54 t ha". The lowest seed
yield (0.96 t ha ') was obtained from the variety BARI Shari a 13 ..
Improved Tori 7 and SAU Sharisa I produced 1.34 and 1.10 t ha" seed
yield respecti 'ely. The 30 cm row spacing gave the highest seed yield of
1.44 t ha" followed by 45 cm row spacing (1 .23 t ha-1). The maximum seed
yield of rapeseed could be obtained by using BARI Sharisa 9 sown 30 cm
apart keeping 5 cm plant to plant distance .
