“…Los patrones de distribución de fotoasimilados depende en gran medida del crecimiento de las plantas (Li et al, 2015;Osorio et al, 2014). En el cultivo de tomate se obtiene una gran variedad de cultivares con características de crecimiento indeterminado y determinado (Mbonihankuye et al, 2013;Maboko et al, 2017). Para el caso de los cultivares de tipo de crecimiento determinado durante la fase vegetativa los fotoasimilados se translocan para la formación y crecimiento de tallos, hojas y raíces, y posteriormente gran parte de esta se transfiere a las flores y frutos (vertederos) cuando inicia la fase reproductiva.…”

Los cultivos de tomate y papa son productos agrícolas de gran importancia a nivel mundial por su valor nutricional e industrial. La distribución de fotoasimilados en los órganos vertederos de estos cultivos depende en gran medida del metabolismo y partición de carbono generado en los procesos fotosintéticos, en la dinámica tanto de los órganos fuente y vertedero como en la actividad de enzimas vinculadas al metabolismo de azúcares, así como factores ambientales y nutricionales. Basado en esto, el objetivo de este documento fue revisar y discutir sobre el conocimiento actual de la distribución de los fotoasimilados en los órganos vertederos y los factores que pueden afectar este mecanismo en los cultivos de tomate y papa. De acuerdo con la información recopilada en artículos de investigación y de revisión recientes, se reporta que alrededor del 80% o 90% de los fotoasimilados producidos en los órganos fuentes en los cultivos de tomate y papa son transportados o translocados hacia los órganos vertederos de interés comercial (frutos y tubérculos). Tanto el desbalance en fuente/vertedero, así como el estrés hídrico y nutricional, en especial, deficiencias de nitrógeno y potasio afectan significativamente la distribución y transporte de los fotoasimilados. En contraste con los efectos de la calidad de la luz puede mejorar la carga de fotoasimilados en los órganos vertederos y mejorar atributos de la calidad como aumento en el tamaño de los frutos y concentración de azucares. Sin embargo, aún faltan más investigaciones que corrobore este efecto bajo condiciones de campo o en invernadero en las condiciones del trópico.

“…The most commonly cultivated crop under greenhouse conditions in Ghana is tomato. To ensure sustainable tomato production, identifying adaptable and appropriate agronomic practices is highly recommended to improve yield and fruit quality, which could lead to increase in profit margin as well as meet consumer preferences (Maboko et al, 2017). Such agronomic practices include plant spacing, choice of cultivar (Maboko et al, 2017), and topping (Robinson and Kolavalli, 2010).…”

“…A recommended number of plants per unit area contributes to adequate utilization of the available planting space, thus ensuring an even distribution of water, nutrient, light, and air. However, an unregulated plant spacing may result in a relatively lower yield and poor fruit quality (Maboko et al, 2017). Tomato yield and yield components have been reported to be greatly affected by plant spacing (Balemi, 2008;Castoldi et al, 2010;Maboko et al, 2017).…”

Tomato is an important vegetable in Ghanaian diet and contributes enormously in livelihood improvement. Tomato production is threatened by a high prevalence of biotic and abiotic stresses as well as increased postharvest losses and poor agronomic practices, thereby resulting in massive importation of tomato and its products to meet the local demands. The recent introduction of greenhouse vegetable cultivation technology in Ghana is a sustainable attempt in addressing and ensuring year-round production of vegetables including tomato. However, research on agronomic practices targeted to improving yield and fruit quality under greenhouse conditions in Ghana is scarcely available. Therefore, this study seeks to evaluate the effect of plant spacing and topping on tomato yield and fruit quality under greenhouse conditions. A 3 ×3 factorial treatment arranged in a completely randomized design (CRD) with three replications was used. Two factors, plant spacing and topping with each having three levels, were used. Thus, the levels for plant spacing were 0.15 m × 1.3 m, 0.2 m × 1.3 m, and 0.3 m × 1.3 m while topping treatments at trusses 2, 3, and 4 (control) were done. The results showed that yield was significantly influenced by plant spacing in both experiments. The interaction effect of 0.2 m × 1.3 m plant spacing and topping at truss 2 showed significantly higher yields. Furthermore, juice volume was significantly increased by plant spacing. Again, 0.2 m × 1.3 m plant spacing by truss 2 topping interaction produced the highest juice volume. Therefore, these agronomic practices could be an essential and effective approach in achieving higher tomato production with improved fruit quality under greenhouse cultivation to ensure sustainable food security.

Plant density and fertilization are key practices for improving the fruit quality and yield of vegetables grown in greenhouses. The experiment was performed to investigate the effects of density and fertilization on the fruit yield and quality, economic efficiency of Solanum lycopersicum L. at Duc Trong district of Lam Dong province. The density (50,000; 33,000; 25.000 plants ha-1) and the fertilizer rates (240N – 100P2O5 – 275K2O; 300N – 125P2O5 – 344K2O; 360N – 150P2O5 – 413K2O kg and 420N – 175P2O5 – 482K2O kg ha-1) were studied in a completely randomised split plot design with three blocks. The fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) was produced the highest height (562.39 cm), fruit setting rate (69.87%), number of fruit per plant (95.65 fruits), average fruit weight (106.37 g), fruit yield (441.11 tons ha-1) and marketable fruit yield (204.31 tons ha-1). The density (25,000 plants ha-1) gave the highest fruit setting rate (75.35%), number of fruit per plant (94.84 fruits), average fruit weight (113.24 g), individual fruit yield (10.02 kg per plant) and fruit yield (501.17 tons ha-1). The combination of density (25,000 plants ha-1) and fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) have the highest fruit yield (613.5 tons ha-1), marketable fruit yield (223.91 tons ha-1) and rate of return (2.44). In addition, this combination was the best density and fertilizer level management strategy for greenhouse-grown Lahay 334 tomato cultivar in Lam Dong province, Vietnam.
