Assesment of the Yield Components of Two Tomato Varieties (Solanum Lycopersicum L.) in Hydroponics in Côte d'Ivoire

Aims: The aim of this study was to evaluate the productivity of two tomato varieties in hydroponics with a nutrient solution.

Study Design: The experimental setup adopted for this hydroponic module was a split-plot, with 3 replicates. Varieties were the main factor, while nutrient solution and substrate served as a secondary factor.

Place and Duration of Study: The work was carried out in Bouaké, in central Côte d'Ivoire, over a period of 5 months, from May to September.

Methodology: The tomato varieties F1 Mongal and F1 Lindo were evaluated using a nutrient solution and a substrate of coconut fibers. Observations and measurements focused on vegetative growth, flowering time and production. All data were subjected to an analysis of variance at the 5% level. In case of significant differences, the Tukey test was used for the separation of the means.

Results: The results revealed that the F1 Lindo had an earlier flowering (28 days) than F1 Mongal (30 days) after transplanting. In terms of yield, F1 Mongal was the most productive with 1 292.1 g of marketable fruit per plant compared to 796.6 g per plant for F1 Lindo. In addition, the rate of unmarketable fruit was lower for F1 Mongal (2.5%) compared to F1 Lindo (4.4%).

Conclusion: The F1 Mongal variety is the most suitable for maximizing the yield and quality of the fruits in hydroponics, especially in tropical areas such as the Côte d'Ivoire.
