How to improve tomato production in Morocco - Green Q

  1. 1. How to improve the production of tomatoes in Maroc
  2. 2. Index • Maroc 2009 • Strong – Weak points • View to technical advantages • Improvement step by step • Different scenarios • Passive to active growing • Road map
  3. 3. 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
  4. 4. 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
  5. 5. Conditions for profitable innovation & 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
  6. 6. Short vieuw to different options to improve • Substrate, irrigation, recirculation • Greenhouse structures, light transmission • Positioning of the plants • Heating + Ventilation • Cooling + (de)humidification
  7. 7. 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
  8. 8. 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
  9. 9. 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
  10. 10. 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
  11. 11. Comparisation of different growing concepts with GreenScheduler Principles: • Maroc climate circumstances • Variety Pristilla crafted on Maxifort • Planting begin August • First flowering begin September • First harvest begin November • Last harvest medio June
  12. 12. GreenScheduler calculates with: crop density fruit size flower speed global radiation artificial light
  13. 13. Greenscheduler Input Blue: is the lightcurve from Agadir Yellow: is desired light for the crop
  14. 14. The GreenScheduler Crop density planning Variety Light conditions Balance Result Load and production
  15. 15. Results of different growing concepts Type greenhouse Brutto production Percentage class 1 nett production Increase nett production Traditional 29 kg 60% 17.5 kg Plastic + c.v + substrate 33 kg 75% 24.5 kg 40% Glass + c.v + substrate 38 kg 75% 28.5 kg 60% Glass, heat + cv + climate control 43 kg 85% 37 kg 110% Cooled glass desert gh 86 kg 85% 73 kg 400% 12 months
  16. 16. Production graphics Glass with heating and ventilation 37kgGlass with ventilation 28,5kg Traditional Agadir Plastic with ventilation 28,5kg
  17. 17. Production curve of the desert greenhouse
  18. 18. Light levels Netherlands versus Agadir Radiation 0 500 1.000 1.500 2.000 2.500 41 46 51 4 9 14 19 24 29 34 39 44 49 2 week number Radiation(J/cm2/day) 0 500 1.000 1.500 2.000 2.500 global usable desired 1.800
  19. 19. With active crop management and good tools in Holland and USA greenhouses produced100 kg/m²
  20. 20. 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
  21. 21. Active management of the growing process can be very profitable Radiation CO2 Feeding Water (plant) temperature humidity
  22. 22. There are different scenarios to go from A to B
  23. 23. 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
  24. 24. When will this giant wake up
  25. 25. Questions?
