In Côte d’Ivoire, tomato cultivation is hampered by the presence of parasites in cultivated soils. However, every year the country releases large quantities of agro-industrial residues with agricultural potential into the environment, which are capable of alleviating this situation. The aim of this study was to assess the agricultural potential of carbonised rice husks, carbonised sawdust and cashew pellets with a view to developing substrates for soilless tomato production. In addition to the control (Soil), five treatments based on the above-mentioned residues were set up and laid out in a completely randomised block design. The parameters analysed included the physico-chemical properties of the soil, in particular water retention capacity, pH, and concentrations of organic matter, total nitrogen, assimilable phosphorus and potassium. In addition, the agronomic parameters considered included plant height and diameter, fruit number and mass, and yield. The results revealed that cashew pellet (C100) is richer in nitrogen (2.1%) but very acidifying (pH = 4.6). Substrates based on rice and sawdust offer good physico-chemical conditions. In terms of productivity, treatments SBC271 (17.93 t.ha-1) and SBC55 (14.69 t.ha-1) gave the highest yields after soil (19.85 t.ha-1). This research has shown that it is possible to develop soilless growing substrates from these residues in order to sustainably increase market garden production.

In Côte d’Ivoire, tomato cultivation is hampered by the presence of parasites in cultivated soils. However, every year the country releases large quantities of agro-industrial residues with agricultural potential into the environment, which are capable of alleviating this situation. The aim of this study was to assess the agricultural potential of carbonised rice husks, carbonised sawdust and cashew pellets with a view to developing substrates for soilless tomato production.

Abstract: (french)
En Côte d’Ivoire, la culture de tomate est contrariée par la présence des parasites des sols cultivés. Pourtant, le pays rejette chaque année dans l’environnement de grandes quantités de résidus agro-industriels à potentiel agricole qui sont capables de pallier cette situation. L’objectif de cette étude est d’évaluer le potentiel agricole de la balle de riz carbonisée, sciure de bois carbonisée et pelote de cajou en vue de développer des substrats de cultures hors-sol en production de tomate. Outre le témoin (Sol), cinq traitements à base des résidus susmentionnés ont été constitués et disposés dans un dispositif en blocs complètement randomisés. Les paramètres analysés englobent les propriétés physico-chimiques du sol, notamment la capacité de rétention en eau, le pH, et les concentrations en matière organique, azote total, phosphore assimilable et potassium. Par ailleurs, les paramètres agronomiques considérés comprennent la hauteur et le diamètre des plants, le nombre et la masse des fruits, ainsi que le rendement. Les résultats ont révélé que la pelote de cajou (C100) est plus riche en azote (2,1 %) mais très acidifiant (pH = 4,6). Les substrats à base de riz et de sciure de bois offrent de bonnes conditions physico-chimiques. Du point de vue de la productivité, les traitements SBC271 (17,93 t.ha-1) et SBC55 (14,69 t.ha-1) ont donné les meilleurs rendements après le sol (19,85 t.ha-1). Cette recherche a montré qu’il est possible de développer des substrats de culture hors-sol à partir de ces résidus afin d’augmenter durablement la production maraîchère.
