EFFECT OF VARIETY AND ROW SPACING ON THE YIELI) AND YIELD CONTRIBUTING CHARACTERS OF RAPESEED

Abstract

An experiment was carried out at the Agronomy Field Laboratory, Sher-eBangla Agricultural University, Dhaka, during the period from November 2007 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 1, 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 BARI Sharisa 9 produced the highest yield of 1 .54

1 haS '. The lowest seed yield (0.96 t h&') was obtained from the variety BARI Sharisa 13. Improved Tori 7 and SAU Sharisa I produced 1.34 and 1.10 t ha S ' seed yield respectively. The 30 cm row spacing gave the highest seed yield of 1.44 t ha1 followed by 45 cm row spacing (1.23 t h15. 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.
