  6. Few facts about Rice Production in India & Bangladesh • Rice productivity in Bangladesh (BD) increased during 20 yrs period of 1990-91 to 2010-11 from 1.71 to 2.94 t/ha whereas in India ,it rose from 1.75 to 2.2 t/ha. During same period rice production in BD almost doubled, from 17.78 mt to 33.91 mt, whereas in India, it increased from 74.29 to 95.33 million tonnes. • From 1997-98 to 2010-11, the Boro area in BD increased from 28% to 42% and productivity from 2.8 t/ha to 3.9 t/ha due to irrigation increase from shallow TWs, better yielding varieties and high fertilizer use. • In WB during last 10 years there was increase in productivity of Aus (20-22%) and Aman but Boro remained stagnant (1999-2008)

  7. Reasons for higher productivity in Bangladesh • Larger boro rice area (42%) with 100% irrigation. Boro contributes 55% of total rice production. • Primarily HYVs and hybrids (approx. 7%) • Good boro season rice varieties • Higher (2430 mm annual) & extended period (May to October) rain fall • Soils suitable for rice, generally heavy textured & fertile.

  8. Suggested varieties for WB Aus: In major areas like Jalpaiguri, Coochbehar, Dinajpur, Murshidabad and Nadia there is need to evaluate/promote HYVs and hybrids. Aman: • In Gangetic / Damodar/ Kangsaboti river plains promote flood tolerant (Sub1) varieties • Replace Swarna with Swarna-Sub1 particularly in Hooghly, Burdwan, Lowlands of Murshidabad, Nadia, 24 parganas(North), Howrah, PurbaMedinipuretc. • In Western part promote drought tolerant varieties like Sahbhagi dhan, Susk Samrat. • For coastal areas salinity tolerant vareities (e.g CR dhan 405/406; CSR 36; IR64-Saltol) may be more suitable. Varieties with both flash flood and salinity tolerance are needed. Boro • Promotion of hybrids & HYVs suited for boro. • For coastal areas promote salinity tolerant varieties like CR dhan 405 (IR64-Saltol; BR28-Saltol etc.)

  9. Suggested Actions for WB Immediate • Characterization of stress-prone areas • Development and implementation of varietal and seed plan for different areas and seasons • Replace mega variety Swarna (MTU2029) with its improved version (Swarna Sub1) • Varietal replacement • Promote drought tolerant rice varieties in drought-prone areas • Improve seed replacement • Ensuring availability of quality seed of suitable varieties • Increase in boro area by increasing irrigation facilities and promoting salinity tolerant rice varieties in coastal saline areas • Timely seeding & transplanting

  10. Suggested Actions Long term • Increase boro area by increasing irrigation facilities. • Develop better HYVs & hybrids for boro and aus seasons • Multiple stress tolerant (salinity + submergence tolerant \; stagnant flood + flash flood; drought + submergence tolerant) rice varieties particularly for Aman

  11. Policy Issues Collaboration among SAARC countries • Varietal and seed exchange • Joint evaluation of varieties • Acceptance of research data from one country for the varietal release in other country • Joint release of varieties for more than one country for similar agro-climatic condition etc.
