Using High-Wire Cucumber growing system in Med-Tech Glass Greenhouse at Commercial Farm - Unaizah, Al-Qassim Region

Status: Finished
Year: 2019
Project type Using High-Wire Cucumber growing system in Med-Tech Glass Greenhouse at Commercial Farm - Unaizah, Al-Qassim Region
​​​​​ Background

Estidamah tested a new cropping system called “high-wire system”. In this case, the training-wire can be elongated and shifted aside to cope with the continuously growing stem (up to 60 cm a week). Of course, the continuously growing stems will just as well create a large bunch of stems. But in the high-wire system, the bunches result from de-leaved stems and are at the bottom side of the crop. Therefore, the bunch of stems will be much less messy. Hence, one crop cycle can stay productive for a longer period and increase product per kg

​Experiment Setup

The experiment was conducted in a commercial farm in Al-Qassim region using med-tech glass-covered greenhouses with soil cultivation

Experiment History

  • Training cucumber in two systems (high wire and umbrella)
  • Planting date April 2019
  • Planting density 2.5 plant/m2
  • Cucumber variety: Zahran from Enza Zden

Goals

Testing a new cropping system called a high-wire system in comparison to the traditional Umbrella system

The main factors studied are:

    Using High-Wire Cucumber Growing System in Med-Tech Glass Greenhouse at the commercial farm

Result overview

Effect of training system on cucumber irrigation and cooling water and energy consumption at the commercial farm

Items High-wire High-wire
Irrigation water consumption (L/m2) 1020 850
Irrigation water consumption (L/plant) 43.6 69.4
Cooling water consumption (L/plant) 64 55
Return per m3 (SAR/m3) 60.8 30.6
Energy consumption (Kw/h/m2) 35 31
Energy consumption (Kw/h/kg) 1.5 2.5


Effect of training system on monthly cucumber production at the commercial farm

 

According to the results of this trial, yield (kg/m2) was improved by 90%, by using a high-wire cropping system, while yield per plant was improved by 91%. The harvest period was increased by 30% as compared with the umbrella system.


Items Umbrella Hi-wire
Plant height (cm) 4.4 6.9
Yield (kg/m2) 12.25 23.39
Yield per plant (kg/plant) 4.9 9.4
Number of fruit per plant 65 125
Fruit class A % 82.5 95
Fruit class B % 17.5 5
