Summary
This 2002 comparative field trial examined the performance of open versus closed greenhouse systems for tomato cultivation, assessing both productivity and fruit quality outcomes. Closed systems (typically with climate control and recirculation) were compared against open or naturally ventilated structures, which represent different capital and resource intensity approaches in greenhouse horticulture. The work contributes to understanding the trade-offs between system complexity, environmental control, and horticultural output in protected cultivation.
Regional applicability
Findings from Turkey's greenhouse tomato sector may have partial relevance to United Kingdom protected cropping, though UK growing seasons and ambient conditions differ significantly. Turkish research on closed systems is particularly relevant given the UK's growing interest in high-tech and controlled environment agriculture, though energy costs and climate profiles would necessitate local validation of any recommendations.
Key measures
Likely included: tomato yield (kg/m² or total harvest), fruit quality attributes (size, firmness, sugar content, colour), and potentially greenhouse environmental conditions and resource use efficiency
Outcomes reported
The study compared tomato yield and quality metrics between open and closed greenhouse production systems. Specific quality parameters measured likely included fruit characteristics such as size, colour, soluble solids content, and possibly disease incidence or pest pressure.
