Abstract
In order to evaluate the effect of humic acid on quantitative and qualitative characteristics of strawberry (Fragaria ananasa cv. 'Aromas'), an experiment was conducted as factorial arrangement in randomized complete block design with three replications in a commercial hydroponic greenhouse. The rooted daughter plants of 'Aromas' strawberry were planted in pots containing perlite and cocopeat (1:1). Humic acid were sprayed on the plants when they were completely established. The treatments consisted of different concentrations of humic acid (Greenhum containing 13% humic acid) (0, 1.5, 3.0 and 4.5 mg l-1). Certain traits were measured including leaf chlorophyll index; the weight, length, width and length/width ratio of the fruits; number of fruit in plant; yield of single plant in a 2months period; malformed fruit percent; total soluble solid percent and fruit firmness. Results indicated that the application of humic acid had positive influence on fruit number, total yield of plant, TSS, fruit firmness and chlorophyll content. Generally, foliar application of humic acid led to the improvement of quantitative and qualitative characteristics of this cultivar of strawberry. Consequently, the application of 1.5-3 mg l-1 humic acid is recommended in hydroponic culturing of strawberry.
