Influence of fertigation on the biochemical and quality parameters of strawberry cv. Nabila under polyhouse condition

Abstract

This study was conducted to find out the relationship between mineral nutrition and fruit quality in strawberry. The experiment involved three levels of fertilizers as treatments based on the recommended dose of fertilizers 150: 100: 120 kg NPK /ha (Kachwaya, 2014) viz., T1 -75% RDF, T2 -100% RDF and T3 -125% RDF with seven replications in randomized block design. The fertilizers were applied at critical stages viz., vegetative stage, flowering stage and fruiting stage through fertigation. Significant differences in the content of TSS (°Brix), sugar to acid ratio, ascorbic acid (mg/ 100 g) and anthocyanin (mg/ 100 g) were observed by the application of nutrients during two years of study while other parameters such as titratable acidity (%), total sugars (%), reducing sugars (%) and non-reducing sugars (%) were not affected.
