EFFECT OF NITROGEN AND SULPHUR ON YIELD AND YIELD COMPONENTS OF RAPESEED

Abstract

A field experiment was conducted to evaluate the effect of nitrogen (N) and sulphur (S) on yield and yield components of rapeseed (BARI Sarisha-14) at Sher-e-Bangla Agricultural University Farm, Dhaka-1207 during November, 2015 to February, 2016. The experiment was consisted of four levels of nitrogen viz., N 0 = 0 kg ha -1 (control), N 1 = 60 kg ha -1 , N 2 = 120 kg ha = 180 kg ha -1 ;

and four levels of sulphur i.e., S 0 = 0 kg ha -1 (control), S = 15 kg ha -1 , S 2 = 30 kg ha -1 , S 3 = 45 kg ha -1 . Levels of N and S showed significant effect on yield and yield contributing characters of BARI Sarisha-14. Results showed that application of 120 kg N ha -1 with 45 kg S ha -1 gave the maximum yield. Results also revealed that the highest plant height, number of branches plant -1 , number of siliquae plant -1 , siliqua length, number of seeds siliqua , 1000-seed weight, seed yield, stover yield, biological yield and harvest index were obtained from the combination of 120 kg N with 45 kg S ha

-1 .
