Abstract
The objective of this study was to assess the effectiveness of specific complex fertilizers registered for use in organic farming systems in enhancing the fruit quality of cultivated strawberry plants.
In general, pre-harvest treatments, specifically the application of designated complex fertilizers, have demonstrated efficacy in improving post-harvest crop performance and, correspondingly, enhancing the quality of strawberry fruits.
The study spanned two consecutive years (2022 and 2023) and was conducted on a strawberry crop situated in the southern region of Romania, specifically within the Vlăsia Plain.
The study incorporated three strawberry cultivars, namely ‘Onebor,’ ‘Premial,’ and ‘Sibilla.’ The cultivation method employed followed a traditional approach, involving field cultivation in double rows on plots covered with agro-textile foil, and irrigation was facilitated through a drip irrigation system.
Strawberry plants underwent treatment with various categories of biostimulants, including salts of humic acids, humic acids, fulvic acids, amino acids, micro- and macroelements, live bacteria, and other readily absorbable substances.
The application was administered from pre-flowering stages through berry maturation, adhering to commercially recommended dosages.
The experimental treatments consisted of two applied variants: V1, a combination of ‘Etamin’ and ‘BioHumus Sol,’ and V2, solely ‘Etamin,’ in comparison to the untreated control variant.
The fruit samples comprised 20 fruits collected for each repetition and each of the four harvests from each year.
During each sampling event, measurements were taken for fruit weight, diameter, length, firmness, titratable acidity, total soluble sugars, and pH. According to the statistical analysis, no significant differences were observed among the three experimental factors in terms of pH, titratable acidity, firmness, color parameters, fruit diameter, and length, as well as mean fruit weight.
