Transcript

  • 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. 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. Bangladesh statistical informationPopulation : 164 millionArea: 144 000 km2Agricultural land: 90 000 km2Forest area: 8664 km2
  • 4. Outline• Background• Approach taken• Possible constraint• Potential collaborations and prospects

  • 8. Aim of the projectIncrease pulse production• In rice cropping system• New agronomic practice• Capacity building of the researchers and growers
  • 9. Pulses Lentil Field Pea Mung Bean
  • 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. 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. Widen window from rice sideT. Aman BRRI dhan33 119 days BRRI dhan49 141 days
  • 13. Super early lentil Local lentil (flower in 65 d) Super early lentil (flower in 50 d)
  • 14. Why Relay Cropping• Resource capture (e.g. moisture, nutrient)• Conservation tillage• Hasten maturity
  • 15. Lentil into standing rice Pea after rice harvest Lentil after rice harvest
  • 16. At field dayHappy Farmer with his relay Pea crop
  • 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
  • 18. Crop Calender J F M A M J J A S O N D Boro Aman Lentil F. Pea G. PeaKharif 1SowingHarvest
  • 19. Constraints for growing legumes • Soil Waterlogging • Diseases and PestsThese constraints have adverse effect on plant growth and yield
  • 20. Boro riceLentil Soil Waterlogging Drought
  • 21. Rust Flower dropping caused by thrips Stemphylium blightPowdery mildew
  • 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. 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. Potential collaboration cont......• Similar cropping pattern to Bangladesh • Myanmar (need to explore) • India (Eastern) • Nepal (relay cropping of lentil)
  • 25. Dimension of impacts • Nutritional benefit • Water use (resource capture) • Climate change and mitigation • Greenhouse gas emission • Energy budget • Soil health • Beyond agronomy
