Abstract
Effects on fruit quality of preplant fertilization and fertigation in strawberry were studied in a field experiment established August 2003 in South East Norway. Half the field was fertilized at planting and fertigated with a low nutrient rate from spring 2004 (T1), while the second half was unfertilized at planting but fertigated with a relatively high nutrient rate from spring 2004 (T2). Berries were harvested three times per week during the first harvesting year. Samples of berries from early season, mid season and late season were analysed for soluble solids, pH, titratable acidity, colour, vitamin C, antioxidant activity (FRAP) and mineral concentration. The results were correlated to leaf mineral concentration in dry matter. T1 gave larger and darker berries compared to T2. The other quality parameters and mineral content in strawberry fruits were not significantly influenced by the two fertilizer strategies. Soluble solids, pH, titratable acidity and colour varied significantly through the season, while vitamin C and antioxidant activity (FRAP) was unaffected by fertilizer treatment, berry size and time of season. The results gave a general view of the quality parameters in the strawberry cultivar ‘Korona’.
