The study investigated an in vitro propagation of Manihot esculenta Crantz in a substituted substrate regime. The aim was to proffer and affordable alternative to the expensive high tech media formulations usually employed in tissue culture protocol. The experiment was conducted on laboratory bench, using standard tissue culture and micropropagation methods under aseptic conditions. The morphogenesis effect of the substrate was determined based on the integer number of explants’ callus and adventitious shoot regeneration. Results showed that MS + Agar, supported embryogenic callus formation with 38% viability, NH4NO3 + KH2PO4 + Agar, supported same with 29%. MS + 2, 4-D + BAP +Agar supported shoot establishment with 32%. While NH4NO3 + KH2PO4 + Zea mays extracts + Agar, did same with 43.26%. MS + Soil, supported callugenesis with 27% viability while NH4NO3 + KH2PO4 + Soil supported the callus establishment with 25%. MS + 2,4 - D + BAP + Soil, supported shoot establishment with 38.41% viability while NH4NO3 + KH2PO4 + Zea mays Extracts + Soil supported same with 36%. The application of crude Zea mays seedling extracts can serve as potent alternative to the synthetic 2, 4 – D and BAP, in in vitro somatic cell morphogenesis. NH4NO3 + KH2 + PO4 can substitute for the MS salt in the same protocol. Loamy top soil can be a good alternative to agar powder as gelling agent in cassava somatic cell embryogenesis and shoot regeneration. Keywords: Ammonium nitrate, Potassium biphosphate, MS salt, axillary meristem, morphogenesis.

<p>Shiny dome-like structures measuring less than 1mm in length were excised aseptically from shoot tip buds of infected of two cassava (<em>Manihot esculenta</em> Crantz) local cultivars (Boma and Mpelo Nlongi) and cultivated <em>in vitro</em> in two types of media with different combination of growth hormone: Murashige and Skoog supplemented of sucrose (20 g/l), Naphtalenacetic acid (NAA, 10 μM), Ben-zylaminopurine (BAP, 0.66 μM) as well as Gibberellic acid (GA3, 0.1 μM) with 80 mg/l of Adenine sulphate and MS-free growth regulators. After four weeks, data were scored: 29.5% responding explant with callus formation and 20.5% responding explants to shoot development in the medium with growth regulators for the cultivar Boma whereas the cultivar Mpelo-Nlongi presented 5.7% and 25.7% respectively of callus formation and shoot development. The cultivar Boma presented a tendency more pronounced for the callus formation rather than with the shoot development contrary to the cultivar Mpelo-Nlongi. In regards of this experiment, it was shown that the media composition and genotype are essential factors, which influence in vitro growth, mainly the shoot development, in the culture of meristems for cassava local accessions.</p>
