How to improve the
production
of tomatoes in Maroc
Index
• Maroc 2009• Strong – Weak points• View to technical advantages• Improvement step by step• Different scenarios• Passive to active growing• Road map
Maroc 2009
• 5.000 ha tomatoes under plastic (Agadir) • Big scale companies, professional organisation
and management• Low cost, low tech focus• Production level tomatoes 250 - 300 ton/ha• First quality 60 - 65%• Growing in the soil• Excellent growing climate
Strength - Weakness
• Climate• Agri Centre infrastructure• Good design and
organisation of nurseries• Low cost level labour• Crop protection• Professionals with proven
production history
• Availability of water• Still growing in the soil• Production level per m²• Sensitive on climate• Sensitive on nematodes• High use of water,
chemicals and fertilizers per produced kg
Conditions for profitableinnovation & improvement
New methods of production must be:
• Economic feasable• Technical reliable and controlable• To the community and market environmental
sustainable methods and a clean product
Short vieuw to differentoptions to improve
• Substrate, irrigation, recirculation
• Greenhouse structures, light transmission
• Positioning of the plants• Heating + Ventilation• Cooling +
(de)humidification
Substrate, Irrigation,Recirculation
• Better crop management• Saving on fertilizers• Less sensitive for nematodes• Better control of fruit quality• Yearly costs € 2.- / m²
Benefits• Increase nett production 25%• Saving water 30% per kg /tom• Saving 30% fertilizers
Greenhouse structures light transmission
• Okt-March 1% light =1% production• Light transmission glass
greenhouse 70 - 75%• Light transmission modern plastic
greenhouse 60 - 65%• Light transmission average Agadir
greenhouse 45 - 50%• Only more efficient use of surface
gives 20% more production
Heating and controled
ventilation • Active management of the
greenhouse climate• Heating + controled ventilation
will give better control of plant load and higher winter production
• Better control on climate is better control on quality of plants and fruits
• Active growing gives better forecast and control on the production film and result
Cooling+dehumidification
• This is formula 1 growing with high investment and yield
• Greenhouse climate quality and production can be under control totally
• Year round production necessary for ROI
• This concept is worldwide the new rising trend
Comparisation of differentgrowing concepts withGreenScheduler
Principles:
• Maroc climate circumstances• Variety Pristilla crafted on Maxifort• Planting begin August• First flowering begin September• First harvest begin November• Last harvest medio June
GreenScheduler calculates with:

The tomato producers of Agadir have a lot of advantages
Agadir 2009• Climate is excellent• Companies are
professional• Centre of tomato
producers• Strong competitor in the
tomato producers match• Production system is
passive and can be more efficient
Agadir to active growing• Better use of climate• More efficiency on :
water fertilizers chemicals surface
• Lower risk on diseases• Better fruit quality• Cleaner product• Stronger market position
Active management of the growing process can be very profitable

There are differentscenarios to go from A to B
Road Map
• Inventarisation and study on reliable techniques
• Design of some alternative growing concepts
• Analyse of feasability, costs and yields of the designs
• Selection of most promising growing concepts
• Building a demo centre to test these concepts
• Implementation of new growing concepts and growing techniques to the Agadir producers
When will this giant wake up
