Summary
This field trial investigated the effects of different nitrogen to potassium molar ratios in fertigation systems on the quality of strawberries grown under greenhouse conditions in Brazil. The study contributes to understanding how nutrient stoichiometry in soilless cultivation affects fruit quality traits. The work is situated within broader research on optimising nutrient delivery in intensive horticultural systems.
Regional applicability
Whilst conducted in Brazil's climate and greenhouse infrastructure, findings on N:K ratio optimisation in soilless strawberry cultivation have potential relevance to United Kingdom protected horticulture. UK growers using fertigation systems could test recommended ratios; however, differences in cultivar selection, water quality, and greenhouse management practices mean results should be validated locally.
Key measures
N:K molar ratio in fertigation solution; strawberry quality parameters (likely including fruit size, sugar content, acidity, and/or nutrient composition)
Outcomes reported
The study examined how varying nitrogen to potassium molar ratios applied through fertigation affected quality parameters of greenhouse-grown strawberries. Quality metrics likely included fruit composition, yield, and post-harvest characteristics.
