1.Introduction
In sub-Saharan Africa more than 95% of farmed land is rainfed
The majorities of the population make their living from rainfed agriculture, and depend to a large extent on small-holder, subsistence agriculture for their livelihood security
Climate variability plays an important role in determining productivity of much of the world’s rain-fed grown annual food crops in the tropics

1.Introduction……
In areas where rainfall is erratic, has high temporal and spatial variations or where short dry periods can be expected in the wet season, as it frequently occurs in the Rift Valley area of Ethiopia, relying on rainfed agriculture poses substantial risks to farmers

1.Introduction……The optimum transplanting date for rainfed vegetable production forecasted by INSTAT+ around Melkassa was found to be on 177 DOY.
Using this reference transplanting date, evaluation of rainfed vegetable production using CropWat model simulation during the start of rainy and crop planting season (July) results indicated that most vegetable crops were severely stressed when transplanted on 3rd of July

1.Introduction..
Growers should be told that there is high yield reduction under rainfed condition (vegetable crops, even other cereal crops)
Rainfall did not feed Ethiopian population in most areas…(small size-major export beans problem)
Use of either supplementary/ full irrigation improved the livelihood of irrigation users through improved crop production and productivity
Availability of markets and consumers demand for horticultural crops drove up the expansion of irrigated agriculture systems in Ethiopia.
Tomato and onion are among the most irrigated vegetable crops of significant economic value in the country but the full potential has not been exploited
Large areas are coming under irrigation every season and year-round production of irrigated crops has become very common.

3. Major Challenges in Irrigated Horticultural Crops Production Value Chain
Rainfed/ irrigated crops production depends on supply of good quality of seeds as seed quality is very important in horticultural crops production since it is the initial key inputs in household irrigated farm business, all other following remaining farm activities are depends on.
“New Chapter”: Development of proper crop management & inputs ----that can be used by growers, by growers --------not variety
![Page 30: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/30.jpg)
3. Major Challenges…The highest percentage, 35.48% of tomato growers replied that the most seed sources for their tomato cultivations are from open market,
while 29.03% of tomato growers use as seed sources from another farmer.
These tomato growers replied that the seeds they use are very low quality.
…… we continued developing varieties --- without making those released/ best ones available for growers
![Page 31: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/31.jpg)
3. Major Challenges…
Over 45% of onion growers obtain their onion seeds from open market;
followed by 22.68% who obtain onion seeds from another farmer.
![Page 32: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/32.jpg)
3. Major Challenges…
Among the major problems onion growers are facing are about 25.31% growers replied that the seeds they use are not true type and
19.14% has explained that the onion seeds used are not true type and are poor in germination, the bulb were non-uniform, variable bulb colors with white color rather than red and, variable in shapes and due to high out crossed seed and other adulterations.
![Page 33: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/33.jpg)
3. Major Challenges…
3.2. Fruits
Fruit production depend on quality planting materials Seedling propagation and multiplication No supply of selected scion variety with appropriate root stock variety
Fruit growers do not get grafted and quality materials, they plant seedling materials -- with full of problems
![Page 34: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/34.jpg)
3. Major Challenges…
No planting material (seedling) quality control
Some private…. sell uncertified, diseased infected seedlings
No certification at all
Pest introduction …. from one area to another
![Page 35: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/35.jpg)
2. Potentials…Private Nursery
![Page 36: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/36.jpg)
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)
![Page 37: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/37.jpg)
3. Major Challenges…
3.1.3. Availability of specific production packages for specific crops and seasons
Year round vegetable planting (difficult to formulate agronomic and irrigation package)
(all production packages should be season specific)
![Page 38: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/38.jpg)
3. Major Challenges…2.3. Absence of defined crop agronomic management practices ---for each main crops –for each major production area
Many pieces of practices…….spacing + fertilizer rate + … + ….+…. row planting=
Verified---validated---demonstrated
Growers 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)
![Page 39: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/39.jpg)
3. Major Challenges…
2.4. Absence of harvest, post harvest management and standards horticultural crops (NO)
Is there extension in these area of intervention?
2.5. Packing and transport system
Papaya in a sack = like wheat/ teffbanana in ISUZU-----60-70 quintals (6-7 tons)
All fruits ----------- similar way
![Page 40: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/40.jpg)
3. Major Challenges…
3.1. Poor skill in horticultural crops production Irrigated horticultural crops- require special skill
3.1. Poor skill in irrigation water related managementssupplementary/ full
Irrigated crops production requires(special irrigation skill)
(Is there extension that cope up with the requirement ?)
![Page 41: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/41.jpg)
3. Major Challenges…Rainfed vegetable –requires supplementary irrigation
Farmers field (End of August)
Mid of September
(false maturity)
![Page 42: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/42.jpg)
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
![Page 43: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/43.jpg)
3. Major Challenges…
Supplementary irrigation is required during dry spells for 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 year
Seasonal crops (vegetable) irrigation requirement is not yet supported with knowledge
All irrigation users (growers) use their own experience
![Page 44: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/44.jpg)
3. Major Challenges…
Many –many irrigation related publications are available , (thesis works), but not synthesised in to useable forms for growers
Irrigated 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 of development workers
![Page 45: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/45.jpg)
3. Major Challenges…
Irrigated crops growers in the country practice arbitrary production techniques from season to season and from location to location, from crop to crop.
In addition, pesticide and fertilizer application as well as irrigation water management practices are under farmers’ traditional intuition
![Page 46: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/46.jpg)
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?
![Page 47: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/47.jpg)
3. Major Challenges…Many GO, NGOs, and others are involved in irrigated horticulture development, -- in development of irrigation schemes
They do not work together along the value chain,
Many of them do not go beyond simple variety demonstration
Less continuity and improvement of practices along the value chain
–generic problems
![Page 48: Potential-interventions in smallholder irrigated horticultural crops production value chain development in Ethiopia](https://reader036.vdocument.in/reader036/viewer/2022062312/554aa8a4b4c905df668b4d33/html5/thumbnails/48.jpg)
4. ConclusionMulti-stakeholder/ actors are required for the development of irrigated horticultural crops
As experience from IPMS, LIVES project will contribute for the development of irrigated fruits & vegetable in Ethiopian agriculture.
We bring changes if all stakeholder work together, through integration with commitments along the value chain
Proper inputs + practices ------- marketing, that bring growers satisfactions, consumers satisfactions
Is it possible to transform small holder into entrepreneurs ----Yes
