DIRECTOR GENERAL’S NOTE
It is my pleasure to make note on the Annual Report of Bangladesh Sugarcane Research Institute
(BSRI) publishing the research results conducted in 2009-2010 cropping season by different research
divisions/disciplines of the institute. Besides research presentation, informations on other activities
have also been included in this report. The compilation, presentation and documentation have been
made in a language for easy understanding even for the common readers. It is a regular publication of
the institute to record the activities of the past one year. It is expected that the preliminary research
results presented in this report would help sugarcane scientists, extension personnel and farmers to
develop advanced research programme and to increase the rate of adoption of sugarcane technologies
in fields.
The institute has so far released forty one (41) sugarcane varieties. Besides variety development, a
good number of improved and potential sugarcane production technologies especially granular gur,
intercropping, pest and disease management, fertilizer management and biotechnological applications
have also been developed and recommended by various research disciplines. These developed
technologies are being disseminated through training, field demonstration, supplying of printed
materials like leaflets & booklets and distributed to end users. I firmly believe that adoption of BSRI
developed varieties and improved production technologies by the farmers would indeed enhance the
increased yields of sugarcane and other ancillary crops in achieving self-sufficiency in sugar and gur
production of our Bangladesh.
