Towards sustainable intensification of maize-legume cropping systems - Ethiopia experience.SIMLESA

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