RESPONSE OF RAPESEED TO THE MANAGEMENT OF SULPHUR AND WEEDS

Abstract

An experiment was conducted at the agronomic field of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November, 2010 to February 2011 to find out the optimum r at e of s ul phur and a ppr opi a t e t i me of we e di ng for BARI Sharisha -14. The experiment was carried out with four levels of sulphur application

matter weight, number of siliqua plant -1 , number of seeds siliqua -1 , number of seeds plant1, number of branches plant -1 , 1000-seed weight, seed yield plant -1 and biological yield. Maximum seed yield plant -1 was observed with 30 kg S/ha

-1 , number of siliqua plant -1 , number of seeds siliqua -1 , number of seeds plant -1 , 1000-seed weight were found to be highest with these three weeding. Plant height as well as dry matter accumulation were also found to be maximum with three weeding.. The increased seed yield plant -1 with three weeding

results. The highest seed yield as well as biological yield was found with the interaction of three weeding a n d 30 kg S/ha which was statistically identical with the interaction of two weeding a n d 30 kg S/ha . Maximum number branches plant -1 0 , number of siliqua plant , seeds siliqua and 100-seed weight was also found from the interaction of three weeding a nd 30 kg S/ha. Two weeding combined with 30 kg S/ha produced almost similar result. 3 -1
