Three pivotal strategies were :
1. Focus on adaptive research and development
2. Availability of low cost zero-tillage seeders
3. Participatory extension – farmer testing

Many development projects relied on
imported zero-tillage (ZT) seeders
European or South American seeders
- big, heavy, & expensive.
Imported ZT Indian seeders
– light & fragile
Can we do better locally?
Can we modify existing seeders?
Can we make our own?
Strategy 2: Low cost ZT seeders
Dr Jacky Desbiolles
Uni of South Australia
Seeder training Erbil 2013
Strategy 2: Low cost ZT seeders
Seeder features: all spring tines, wide-spaced rows, narrow points, seed/fertilizer
delivery, 2 - 4m wide, 3PL or trailed, low cost ≈ $2000-6000.
Seven Syrian village manufacturers: 2008-12: made/sold >100 seeders
Strategy 2: Low cost ZT seeders - Syria
Fabrication of ZT
conversions kits
in Iraq.

Strategy 2: Low cost ZT seeders - Iraq
Kit cost: $1,500.
Two manufacturers in Mosul planned 24 new seeders
plus kits for 40 conversions in 2014.

Strategy 3: Participatory Extension
• stop plowing
• if needed, kill weeds at sowing with glyphosate
• plant early (November)
• use ZT seeder for all crops
• use good quality seed of best adapted varieties
• reduce seed rates; 50-100kg/ha cereals; 100-150kg/ha pulses
• sow consistently at optimum depth (4-6cm)
• use best fertility & weed/disease/pest management
• include non-cereals in rotation IF POSSIBLE
• keep stubble IF POSSIBLE - don’t burn
• graze stubble IF POSSIBLE - doesn’t cancel ZT benefits

Almost all farmers did not change their rotations or crop residue grazing.
Mean farmer yields under ZT plus early sowing and nearby CT fields in Syria.
* Mostly wheat & barley, with some lentil & chickpea
Farmer Evaluation of ZT in Syria
Strategy 3: Participatory Extension
A 2011 survey 820 farmer using ZT & early sowing - on average
the ZT farmer produced about 465 kg/ha (31%) more yield,
reduced fuel and labor costs, and net farm income was increased
by US$194/ha.
If 80% of Syrian wheat farmers adopted ZT, extra 630,000 tonnes
and increase incomes by $254 million.
ZT will be an important strategy for Syria
& Iraq to restart their agricultural economies
and food security.

Future in Iraq ….
Center for CA Research – Uni of Mosul
Plus MoA Baghdad initiative to expand CA into central and
southern Iraq in irrigated areas.
Constraints to Adoption
1) Civil unrest in Syria, Iraq and elsewhere causing disruption.
But there is now a critical mass of experienced farmers,
researchers & manufacturers to
ensure ongoing adoption of ZT
when peace returns.
Constraints to Adoption
2) More attention to food and forage legumes – weed
management, yields, harvestability, wheat subsidies.
3) Value of crop residues for the soil and/or livestock – this
critical question is being investigated in Tunisia & Algeria in the
CLCA project funded by IFAD.
Constraints to Adoption
4) Ongoing technical support for seeder manufacturers,
especially in North Africa and Central Asia.
5) Lack of motivation & poor farm management skills of
small land holders – agriculture is not their main income source.
6) Poor awareness & knowledge - weak research & extension
services in some countries.
7) Inflexibility & dogmatism –
trying to push the whole CA
package at once.
