To reduce the urban population's difficulties in accessing land and also to improve the quality of vegetable production by avoiding telluric diseases, the development of a suitable substrate for hydroponic cultivation has been undertaken. Two varieties of tomato, TMA97 and Lindo were evaluated on three substrates: N. D. COULIBALY et al. / Int. J. Biol. Chem. Sci. 15(1): 200-211, 2021 201 coconut fibers, soy compost and peanut shells. Observations and measurements focused on vegetative growth, flowering time, and yield parameters. The results obtained showed that the best growth was obtained with the Lindo variety on coconut fibres. The highest rate of damaged fruit (37%) was also produced by Lindo on this substrate. On the other hand, the variety TMA97 grown on soy compost gave the lowest (1.3%). Statistically, potential and net yields were identical in the tomato varieties studied. But numerically, the net yields are higher in TMA97 than in Lindo regardless of the substrate used. In the Lindo variety, the highest net yields were obtained with soy compost. Peanut shells gave low yields. For the TMA97 variety, the highest values were produced on coconut fibers; while the smallest values were observed on peanut shells.
