A study was made to determine the influence of incorporate carbonized plant residues, as a soil improver, on the growth and development of Swiss chard (Beta vulgaris subsp. vulgaris). A pot experiment was conduct on two soil types: Vertisols and Luvisol soils. Five variants were develop in three replicates, as follow: 1. Control – pure soil without fertilization; 2. Soil + biochar (BC); 3. BC+N200P200K250; 4. BC+N2\400P200K250; 5. BC+N600P200K250 and the same variants (6, 7, 8, 9, 10) on Luvisol. Irrespective of the different starting supply of nutrients in two soil types, the highest yield of plant mass was recorded in the variant with BC+N200P200K250, followed by the variant with BC+N400P200K250. The fresh mass recorded on Vertisol significantly exceeds that on Luvisol.
