The effect of shoot number per stand on growth rate, yield and stability of yield in three cassava cultivars (TMS 30572, TMS 91934 and NR 8083) were studied at the National Root Crops Research Institute, Umudike, Nigeria for two years. Differences in shoot number per stand were reflected in crop growth rate and stand yields. Increasing shoot number beyond a maximum of two shoots per stand decreased crop growth rate, fresh root yield and instigated variability in cassava yield in both profusely and sparsely branching types. Two shoots per stand would therefore be regarded as the optimum shoot number for ensuring best performance and stable yields in cassava production. Cassava cultivar TMS 30572 sustained the highest crop growth rate, fresh root yield and stable yield among the three cultivars.
