GROWTH AND YIELD OF RAPESEED AND MUSTARD VARIETIES AS AFFECTED BY PLANTING METHOD

Abstract

The field experiment was conducted at the Agronomy field of Sher-e- Bangla Agricultural University (SAU), Dhaka in the Rabi season (November- February) of 2014-2015 to evaluate the performance of varieties on different planting methods of mustard. The treatment comprised of two planting methods and six varieties. The two planting methods were conventional method of sowing (M ) and System of Mustard Intensification (SMI) (M 2 1 ). Six different varieties were BARI Sarisha-11 (V ), BARI Sarisha-13 (V 2 ), BARI Sarisha-14 (V ii

3 ), BARI Sarisha-15 (V ) BARI Sarisha-16 (V 5 ) and Tori-7 (V ). The experiment was laid out in a Split-plot design with three replications. Planting methods was assigned in the main plot and varieties in the sub plot. The planting method affected significantly for the siliqua length, number of siliquae plant 6 -1 1 4 , number of seed siliqua , stover yield, biological yield and harvest index but statistically unaffected for 1000-seed weight and seed yield. It was found that SMI produced 2.28% higher seed yield compared to conventional method. The seed yield of mustard varied for different variety. BARI Sarisha-11 produced the highest seed yield (1386.50 kg ha -1 ) whereas the lowest seed yield (733.10 kg ha ) was given BARI Sarisha-14. BARI Sarisha-11 in SMI method resulted the highest seed yield (1830.70 kg ha -1 ) that might be due to higher number of siliquae (483.47) plant -1 . BARI Sarisha-14 in SMI showed the lowest seed yield (429.80 kg ha -1 ). Thus it may be concluded that SMI was not effective for all varieties i.e the variety BARI Sarisha-11 performed better in SMI method.
