The effect of nutrient solutions of three iron and boron concentrations on yield and, element concentrations in short day strawberry (Fragaria ananassa Duch. ‘Selva’) was studied. The experimental plants were grown in a mixture of peat moss and perlite (70: 30 respectively). They were irrigated with complete nutrient solutions of three different Fe and B concentrations. The solutions contained 5 Fe, 0.75 B; 10 Fe, 1.5 B and 20 Fe, 3 B mg/lit respectively. Other essential elements were added to these solutions in adequate amounts while the pH was regulated at 5.8 ± 0.2. The results indicated that the treatments did not have any effect on yield, but leaf total N, K, and B increased while NO3, P, Ca, Mg and Fe decreased with increasing Fe and B concentration in nutrient solutions. The concentration of NO3, total N, P, and Mg increased in fruits. The results demonstrated that the amount of total N, P, and K also increased in roots with an increase in Fe and B concentration in nutrient solutions. Increasing Fe and B did not increase yield and in lower levels of Fe and B, a lower nitrate concentration was detected in fruits, which is as desired by consumers. So based on the results it is suggested that a lower level of Fe and B (control solution) is a better choice for growing strawberry cv. Selva.
