Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia

  1. 1. Potential-Interventions in SmallholderIrrigated Horticultural Crops Production Value Chain Development Edossa Etissa (Horticulture, Irrigation Agronomy and Plant Nutrition Melkassa Ethiopian Institute of Agricultural Research)LIVES Commodity Value Chain Development Inception Workshop Addis Ababa, 21–24 January 2013
  2. 2. 1.IntroductionIn sub-Saharan Africa more than 95% of farmed land israinfedThe majorities of the population make their living fromrainfed agriculture, and depend to a large extent onsmall-holder, subsistence agriculture for their livelihoodsecurityClimate variability plays an important role indetermining productivity of much of the world’s rain-fedgrown annual food crops in the tropics
  3. 3. 1.Introduction……In areas where rainfall is erratic, has high temporal andspatial variations or where short dry periods can beexpected in the wet season, as it frequently occurs inthe Rift Valley area of Ethiopia, relying on rainfedagriculture poses substantial risks to farmers
  4. 4. 1.Introduction……Table. Rainfall probability of exceedance (PE) using normaldistribution method at Melkassa Kiremit (rainy season) season(1977-2011) (RAINBOW Program) Return period Probability of exceedence Rain fall years (PE) [%] events (mm) 10 10 929.18 5 20 860.69 3.33 30 813.46 2.50 40 774.52 2 50 739.33 1.67 60 705.22 Average 1.43 70 669.85 1.25 80 629.95 1.11 90 577.28 Torrential rain, exceeds 50 mm, many 30-40 mm --- Adama flood
  5. 5. 1.Introduction……The optimum transplanting date for rainfed vegetable productionforecasted by INSTAT+ around Melkassa was found to be on 177DOY.Using this reference transplanting date, evaluation of rainfedvegetable production using CropWat model simulation during thestart of rainy and crop planting season (July) results indicated thatmost vegetable crops were severely stressed when transplantedon 3rd of July

Many visit Melkassa / telephone call from in country/ abroad requesting information on quantity
  28. 28. 2. Potentials… Fruit, vegetable and fruit seedling marketingMillions
  29. 29. 3. Major Challenges in Irrigated Horticultural Crops Production Value ChainRainfed/ irrigated crops production dependson supply of good quality of seeds as seedquality is very important in horticultural cropsproduction since it is the initial key inputs inhousehold irrigated farm business, all otherfollowing remaining farm activities aredepends on.“New Chapter”: Development of proper cropmanagement & inputs ----that can be used bygrowers, by growers --------not variety
  30. 30. 3. Major Challenges…The highest percentage, 35.48% of tomato growersreplied that the most seed sources for their tomatocultivations are from open market,while 29.03% of tomato growers use as seed sourcesfrom another farmer.These tomato growers replied that the seeds theyuse are very low quality.…… we continued developing varieties --- withoutmaking those released/ best ones available forgrowers
  31. 31. 3. Major Challenges…Over 45% of onion growers obtain their onionseeds from open market;followed by 22.68% who obtain onion seedsfrom another farmer.
  32. 32. 3. Major Challenges…Among the major problems onion growers arefacing are about 25.31% growers replied thatthe seeds they use are not true type and19.14% has explained that the onion seedsused are not true type and are poor ingermination, the bulb were non-uniform, variable bulb colors with white colorrather than red and, variable in shapes anddue to high out crossed seed and otheradulterations.
  33. 33. 3. Major Challenges…3.2. FruitsFruit production depend on quality planting materialsSeedling propagation and multiplication No supply of selected scion variety with appropriate root stock varietyFruit growers do not get grafted and qualitymaterials, they plant seedling materials -- with full ofproblems
  34. 34. 3. Major Challenges…No planting material (seedling) quality controlSome private…. sell uncertified, diseased infectedseedlings No certification at all Pest introduction …. from one area to another
  35. 35. 2. Potentials… Private Nursery
  36. 36. 3. Major Challenges…3.1.2. Availability of chemical inputs Fertilizers import is scheduled for rainfed (June) Not available for irrigated agriculture (adulterated) Pesticides- Target pesticide some times not available Chemical spray not scientific based (up to more than 8 times spray)
  37. 37. 3. Major Challenges…3.1.3. Availability of specific production packages forspecific crops and seasons Year round vegetable planting (difficult to formulate agronomic and irrigation package) (all production packages should be season specific)
  38. 38. 3. Major Challenges…2.3. Absence of defined crop agronomic management practices ---for each main crops –for each major production areaMany pieces of practices…….spacing + fertilizer rate + … + ….+…. row planting= Verified---validated---demonstratedGrowers go/ went back to their traditional practices all adopt improved variety, but not agronomic (why ?)As result –do we see improvement of crop productivity over years(not much)
  39. 39. 3. Major Challenges…2.4. Absence of harvest, post harvest managementand standards horticultural crops (NO)Is there extension in these area of intervention?2.5. Packing and transport system Papaya in a sack = like wheat/ teff banana in ISUZU-----60-70 quintals (6-7 tons) All fruits ----------- similar way
  40. 40. 3. Major Challenges…3.1. Poor skill in horticultural crops productionIrrigated horticultural crops- require special skill3.1. Poor skill in irrigation water related managements supplementary/ fullIrrigated crops production requires (special irrigation skill)(Is there extension that cope up with the requirement ?)
  41. 41. 3. Major Challenges…Rainfed vegetable –requires supplementary irrigation Farmers field (End of August) Mid of September (false maturity)
  42. 42. 3. Major Challenges…Rainfed –early rainfall cessation Tomato grown with rainfall only Research field Yield reduction occur for many crops in the Central Rift Valley area such as Teff, maize, beans, & others Under size of export bean/ serious problem No one estimates yield reduction due to early rainfall cessation for any crops
  43. 43. 3. Major Challenges…Supplementary irrigation is required during dry spellsfor many rainfed crops (Central Rift Valley area),Full irrigation is required after cessation of rainfall(short season as compared to crop growth periods)otherwise high yield reduction occur every yearSeasonal crops (vegetable) irrigation requirement isnot yet supported with knowledgeAll irrigation users (growers) use their own experience
  44. 44. 3. Major Challenges…Many –many irrigation related publications areavailable , (thesis works), but not synthesised in touseable forms for growersIrrigated cash crops -four types of producers (small holder, share cropper, tenant producers, large scale producers)Irrigation development agent ….(no skill),Irrigation management is beyond the capacity ofdevelopment workers
  45. 45. 3. Major Challenges…Irrigated crops growers in the country practice arbitraryproduction techniques from season to season and fromlocation to location, from crop to crop.In addition, pesticide and fertilizer application as well asirrigation water management practices are underfarmers’ traditional intuition
  46. 46. 3. Major Challenges…Absence of efficient marketing system Killing vegetable/ horticulture development Daily farm gate price is fixed by traders (Piyasa) Brokers-brokers-, with full of cheating the producers No planned production, … season to season, district to district (no one is giving pieces of advice) long lived problemIs it possible to transform small holder into entrepreneurs?
  47. 47. 3. Major Challenges…Many GO, NGOs, and others are involved in irrigatedhorticulture development, -- in development ofirrigation schemesThey do not work together along the value chain,Many of them do not go beyond simple varietydemonstrationLess continuity and improvement of practices alongthe value chain –generic problems
  48. 48. 4. ConclusionMulti-stakeholder/ actors are required for the development ofirrigated horticultural cropsAs experience from IPMS, LIVES project will contribute for thedevelopment of irrigated fruits & vegetable in Ethiopianagriculture.We bring changes if all stakeholder work together, throughintegration with commitments along the value chainProper inputs + practices ------- marketing, that bring growers satisfactions, consumers satisfactionsIs it possible to transform small holder into entrepreneurs ----Yes
