Transcript

  • 1. Towards Sustainable Intensification of Maize-Legume Cropping Systems- Ethiopia Experience
      • SIMLESA PROGRAM
      • Authors:
      • Dagne Wegary, Abeya Temesgen, Solomon Admasu, Solomon Jemal, Alemu Tirfessa, Legesse Hidoto, Fekadu Getnet and Fred Kanampiu
  • 2. Problem Statement
    • In Ethiopia smallholder farmers predominantly grow maize and legumes in association with livestock.
    • Crop yields are low due to poor soil fertility and lack of use of fertilizer.
      • Conventional tillage methods over time have degraded the resource base
    • Farmers do not use quality seed or fertilizers due to:
      • lack of economic incentives to invest on new technologies
      • Inadequate input – output markets
      • Lack of know how
  • 3. Problem Statement …
    • NARCs and local universities are working in collaboration with CIMMYT and QAAFI, QEEDI and Murdoch University in partnership with local farmers and agri-businesses.
  • 4. Objective :
    • To identify more productive and sustainable practices, and more profitable and resilient farming systems designs that reduce food insecurities and improve rural incomes
    • Milestone:
    • H igh yield and sustainable farming systems attainable under Conservation Agriculture Practices
  • 5. Conservation Agric Vs. Conventional Practices
    • Conservation Agriculture
    • Conventional Tillage
  • 6. Target SIMLESA Project areas Mid-Altitude Dry-land (MAD) zones Mid-Altitude Sub-Humid (MASH) zone
    • Boset
    • Sire
    • Dugda
    • Adami – Tullu
    • Shalla
    • Hawassa – Zuria
    • Meskan
    • Badawacho
    • Gobu – Sayo
    • Bako – Tibe
    • Pawe
    • Guangua
    Mixed crop – livestock systems are predominant farming system
  • 7. Activities done
        • Testing of CA practices vs. Conv. Practices
        • Variety selection (FPVS)
        • Capacity building
    • These trials have been conducted on-station at three research centers: Melkassa, Bako & Pawe RCs
      • Treatments under CA and CP comprised of:
        • Sole maize and sole legume
        • Maize-legume intercrop
        • Maize-legume rotation
  • 8. On-farm activities
    • Treatments:
        • Farmers Practice
        • Conservation Agriculture
        • Conservation Agriculture with tie ridging
    • Number of on-farm trials:
      • in MAD zones : 5 districts and 30 farmers.
      • in MASH zones: 2 districts and 14 farmers.
  • 9. Results SIMLESA best fit treatment vs. CP at MAHZ MADZ
  • 10. Fig. Effect of tillage system and cropping system maize/soybean at Bako (MASHZ)
  • 11. Fig. Effect of tillage system and cropping system maize/soybean at Melkassa (MADZ)
  • 12. Benefits of SIMLESA best fit CA Technology
    • Maize yields in MASH zones increased by >32% in the initial years
    • In the long run CA could increase agricultural productivity in sub-humid, arid and semi-arid areas of Ethiopia
      • soil fertility build up due to crop residue management and
      • proper crop rotation practices
  • 13. Benefits of SIMLESA best fit CA Technology ….
    • CA provides long term merits in maintaining soil physical and chemical properties (replenishment of SOM), soil & water conservation and weed control
    • Intercropping will increase total land productivity and improve resource use efficiency
  • 14. The way forward
    • There is a need to repeat on-station and on-farm trials to fine-tune the results obtained so far
    • Maize/legume varietal compatibility for intercropping
    • Introduction and evaluation of efficient CA equipments could complement the CA packages
  • 15. The way forward….
    • Establish alternative sources feed, fuel and roofing material to enhance residue retention in the fields
    • Establish integrated and innovative approaches for technology scaling out
    • Conduct field days at different levels and organize experience/expertise sharing visits
  • 16. Thank you!
