On Farm Trials

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:

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
