Productivity performance of Pircinque and Jonica strawberry crops on four planting dates in semihydroponic system

Abstract

 This study aims to evaluate strawberry cultivars Pircinque and Jonica productivity on four planting seasons in São Miguel do Oeste, West of Santa Catarina, Brazil. The experiment was carried out during the 2020 harvest, in a semi hydroponic system with slabs, on support protected by a plastic tunnel. The experimental design was completely randomized in a 4 x 2 factorial scheme with four planting seasons and two cultivars, and five replications. The planting dates treatments were: 03/10/2020, 03/30/2020, 04/19/2020, and 05/09/2020. The sampling unit (slab) had six plants, with borders being adopted
at the longitudinal ends. The highest total productivity was obtained with planting on 04/19/20 (758.6g plant^-1). Commercial production did not differ in the planting of 03/30/20 (422,6g plant^-1), 04/19/20 (450g), and 05/09/20 (419.3g). The date of 03/10/20 was the productive planting season with lower commercial (347g plant^-1) and total weight (585.3g plant^-1), and number of commercial fruits. The dates of 03/30/20 and 04/19/20 resulted in a higher expected economic return, both for the
sale of commercial (R$ 5.10 plant^-1; R$ 5.47 plant^-1, respectively) and total fruits (R$ 6.67 plant-1; R$ 7.32 plant^-1)
