Introduction of short duration pulses into rice-based cropping systems in western Bangladesh

  1. 1. Introduction of short duration pulses into rice-based cropping systems in western Bangladesh Imran Malik, Ken Flower, Matiur Rahman, William ErskineCentre for Legumes in Mediterranean Agriculture
  2. 2. Project: CIM-2009-038Partners and Collaborators• ACIAR- funded from January 1, 2011 for 5 years• Commissioned organisation: The University of Western Australia• Collaborating partner: PBA/Vic. DPI (Peas)• Collaborating IARC: ICARDA (Lentils)• In-country coordination: IRRI• Major research partners: BARI, BRRI• Other partners: DAE and NGOs
  3. 3. Bangladesh statistical informationPopulation : 164 millionArea: 144 000 km2Agricultural land: 90 000 km2Forest area: 8664 km2
  4. 4. Outline• Background• Approach taken• Possible constraint• Potential collaborations and prospects

  8. 8. Aim of the projectIncrease pulse production• In rice cropping system• New agronomic practice• Capacity building of the researchers and growers
  9. 9. Pulses Lentil Field Pea Mung Bean
  10. 10. Strategies to achieve the goal • Widen window between rice crops • Early maturing lentil and field pea • Relay cropping of short duration pulses • Short duration Mung bean • Up-scaling of short duration pulses varieties
  11. 11. Cropping patterns targeted Current practice Target practiceAman rice- Fallow- Boro Aman rice-pea-BoroAman rice- Fallow- Boro Aman rice- lentil/pea (relay)-MungAman rice-rabi crops- Fallow Aman rice-rabi crops- Mung
  12. 12. Widen window from rice sideT. Aman BRRI dhan33 119 days BRRI dhan49 141 days
  13. 13. Super early lentil Local lentil (flower in 65 d) Super early lentil (flower in 50 d)
  14. 14. Why Relay Cropping• Resource capture (e.g. moisture, nutrient)• Conservation tillage• Hasten maturity
  15. 15. Lentil into standing rice Pea after rice harvest Lentil after rice harvest
  16. 16. At field dayHappy Farmer with his relay Pea crop
  17. 17. Major findings of year 1• Early aman rice allow green pea before Boro• Identified early pea genotypes• Relay sown lentil/pea between T.Aman and T.aus/Mung• On-farm Lentil (relay sown) and Mung demonstrations

  19. 19. Constraints for growing legumes • Soil Waterlogging • Diseases and PestsThese constraints have adverse effect on plant growth and yield
  20. 20. Boro riceLentil Soil Waterlogging Drought
  21. 21. Rust Flower dropping caused by thrips Stemphylium blightPowdery mildew
  22. 22. Strategies to cope with climate change at agronomic level• Management practice: – Resource capture – Conservation tillage – Modelling reliability of window – Intercropping• Altering inputs: – Cultivars – fertilizer
  23. 23. Potential collaboration and futuredirection • LWR/2008/019 (CCAS)(Developing multi-scale climate change adaptation strategies for farming communities in Cambodia, Lao PDR, Bangladesh and India ) • LWR/2010/080 (OAMC)(Overcoming agronomic and mechanisation constraints to development of conservation agriculture in diversified rice-based cropping in Bangladesh)
  24. 24. Potential collaboration cont......• Similar cropping pattern to Bangladesh • Myanmar (need to explore) • India (Eastern) • Nepal (relay cropping of lentil)
  25. 25. Dimension of impacts • Nutritional benefit • Water use (resource capture) • Climate change and mitigation • Greenhouse gas emission • Energy budget • Soil health • Beyond agronomy
