In Burkina Faso, vegetable production is challenged by low soil fertility and unavailability of irrigation
water associated with numerous dry sequences. The study's objective is to apprehend the performance of polyter and
turbo-bio on soil and tomato productivity. A trial was set up, in a controlled environment and in vegetation vases,
according to a totally randomized complete block design with four replications and twenty treatments resulting from
the combination of soil type, fertilization and water stress. Observations were made on growth and biomass
production assessment. Co2 release, pH, carbon, nitrogen, available phosphorus and moisture content were
measured. The results showed that the polyter and turbo-bio improved the pH, organic carbon, total nitrogen and
available phosphorus of the soil. They induced an increase in moisture content from 2.57 to 113.41% and from 4 to
75.78% for roots biomass production, and from 4 to 61.97% for aboveground biomass production compared to the
control. In a context of global changes, polyter and turbo-bio could be an alternative for improving soil fertility and
tomato productivity in Sudanian zone of Burkina Faso.
