Abstract :

In order to evaluate the effects of foliar application of Calboron (Cal) and Humic Acid (HA) on vegetative and reproductive growth of strawberry (Fragaria ananasa Duch.) cv ‘Aromas’ a factorial experiment was carried out in a completely randomized block design in hydroponic greenhouse. Treatments were  included Cal in 0, 1.5, 3 and 4.5 and HA in 0, 1.5, 3 and 4.5 gl-1 concentrations. Chlorophyll index, plant yield, number of fruit per plant, length to diameter ratio (L/D) of fruit, total soluble solid (TSS), photosynthesis rate and fruit firmness were measured. Results indicated that application of Cal and HA were effective of yield, number of fruit, L/D, SPAD, TSS and fruit firmness. The highest yield, number of fruit and fruit firmness were obtained in interaction of Cal 4.5 and HA 3gL-1. The plants sprayed with Cal and HA had not significantly effect on photosynthesis rate. In general, application of Cal and HA for increasing quantitative and qualitative of strawberry cv ‘Aromas’ is recommended.
