Comparative Study of Two Agricultural Practices on Some Agromorphological Parameters of Ribbed Tomatoes in the City of Korhogo

Abstract

In Côte d'Ivoire, the tomato is the most widely grown and consumed vegetable. Tomato (Solanum lycopersicum) is one of the most essential vegetables worldwide. However, its annual production is insufficient to meet the population's needs. This low production is due to several factors, including non-compliance with good agricultural practices. This study aims to evaluate the effect of these agricultural practices on some agromorphological parameters of tomatoes. The methodology used consisted of applying two agricultural practices to the cultivation of the local variety of ribbed tomato. The experimental design was a Fisher block with three replicates. The agricultural practices of the market gardeners of Korhogo (APMGK) constituted treatment P1, and good agricultural practices (GAP) constituted treatment P2. The observations focused on some agromorphological parameters of tomato. The results showed that GAP gives better growth of tomato plants. Thus, the number of leaves, the length of the stems and the circumference of the stems were respectively 45, 48.76 cm and 3.12 cm for GAP against 37, 42.87 cm and 2.89 cm for APMGK. However, the two agricultural practices gave statistically non-different values concerning the number of fruits harvested and the mass of fruits harvested, whose values were respectively 14 and 0.52 kg for GAP against 12 and 0.45 kg for APMGK. It appears from this study that APMGK, despite some differences with GAP, do not affect the production of the ribbed tomato variety. Analysing the results, it appears that there are some differences between the agricultural practices of market gardeners in Korhogo (APMGK) and good agricultural practices (GAP), particularly concerning the type of fertiliser applied.
