Production of Organic Strawberry (Fragaria x ananassa cv. Oso Grande) Using Three Substrates, in San Isidro de Heredia, Costa Rica

Abstract

The study took place in Las Frambuesas Farm, located in the province of Heredia, Costa Rica, in an experiment evaluating the growth and yield of strawberry plants (Fragaria x ananassa cv. Oso Grande) grown in three organic treatments. The substrates used were compost, vermicompost, and soil from a secondary forest. In order to evaluate treatments, measurements of descriptors were taken, including plant height, number of leaflets, width and length of leaflets, and °Brix. Yields were evaluated on a per treatment basis that measured fresh fruit weight. The treatments of compost and vermicompost reached fresh fruit yields of up to 53.6 Mg/ha and 53.7 Mg/ha per year, respectively. The soil treatment produced up to 24.2 Mg/ha per year. The plants grown in the compost and vermicompost treatments exhibited a greater plant height, width, length of leaflets and number of leaflets, which resulted in higher fruit productivity. The fruits produced in the three treatments reached acceptable values of °Brix.

Key words: compost, Oso Grande cultivar, Fragaria x ananassa, strawberry, vermicompost, organic production.
