Antioxidant compounds in green and red peppers as affected by irrigation frequency, salinity and nutrient solution composition - Journal of the Science of Food and Agriculture, 89(8), p.1352-1359, 2009 .

BACKGROUND: There is a need to encourage more sustainable agricultural practices, reducing inputs of water and fertilisers while minimising any negative impact on fruit quality. The effect of irrigation frequency, salinity and potassium and calcium fertilisation on the content of bioactive compounds and quality attributes of green and red peppers grown with and without substrate was evaluated. RESULTS: Lowirrigation frequency and salinity improved the quality attributes (drymatter, soluble solids content and titratable acidity)of pepper. Low irrigation frequency increased vitamin C content by 23
