Between 2020 and 2021, an experimental investigation was conducted in Tropical conditions to assess the effects of varying levels of nitrogen fertilization (0 kgNha, 0.5 kgNha, 1 kgNha, 1.5 kgNha, and 2 kgNha) on the growth and yield parameters of two strawberry cultivars (Sweet Sensation and Rubygem) in a sandy loam soil. The results demonstrated that the application of nitrogen positively influenced both vegetative (such as plant height, leaf number per plant, canopy spread, and crown diameter) and reproductive (such as number of flowers and fruits per plant, fruit yield, and TSS content) traits of both strawberry cultivars. Furthermore, the findings indicated that Sweet Sensation responded more positively to higher nitrogen doses than Rubygem in all aspects. The data showed that the utilization of 2 kgNha resulted in the highest fruit yield (0.390-0.508 t/ha) and quality traits, including TSS (7.89-9.21%). While there were no significant variations in TSS content among the plants treated with different nitrogen levels, significant differences were observed between the two strawberry cultivars.

Strawberry, Fragaria x ananassa Duchesne (Rosales: Rosaceae), is an important specialty crop in Florida, generating about $500 million in annual revenue. An invasive insect, chilli thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae), has emerged as a major strawberry pest, causing considerable yield and revenue loss in recent years. Pesticide application is the leading control option but is not always recommended due to resistance development.

Background: Reuse of plant growing substrate can contribute to lowering the carbon footprint of horticulture production systems. Here, we assessed the impact of substrate reusing on the root-associated microbiome of strawberries. The cultivars Elsanta and Malling Centenary were grown in a substrate-based hydroponic system using either fresh peat-based substrate or substrate reused up to three times, with comparisons made between not steamed and steam-treated substrate.

A stable supply of transplants with floral buds is required to improve the initial yield of the June-bearing cultivars of strawberry ( × Duch.). A closed transplant production system (CTPS) enables year-round production to meet the demands for the year-round production of strawberries in plant factories.
