Fruit production and leaves mineral content in different cultivars and strawberry cropping systems
This study aimed to test whether the cropping systems affect the fruit production of strawberry cultivars and if the leaf macro and micronutrient content are correlated with plant production, regardless of the system. Strawberry cultivars 'Albion', 'Camino Real', L'Camarosa', 'Ventana' and 'Aromas' were used in two cropping systems, in the soil and in substrate. In both systems, the treatments (cultivars) were arranged in a randomized block design with four replications. Each plot consisted of 10 plants from which six were evaluated for total and marketable number and fresh mass of fruits per plant. In addition to the productive response, the extraction of macro and micronutrients in the leaves was evaluated. Production data in different cropping systems were compared through a combined analysis. Data on macro and micronutrient extraction were evaluated independently in each cropping system for different cultivars. ANOVA was performed and the means were compared by a Tukey test at 5% probability of error. Our results showed that the cropping system affected the strawberry production according to the cultivar. A correlation between production and mineral leaf content was observed only for plants grown in the soil.
