2). This could have been due to the short harvesting interval; maybe a longer interval would have yielded different
results. Use of In-vitro plantlets as starter material resulted in production of more minitubers per plant than use of
minitubers or stem cuttings. This result corroborates with the findings of Bandoni and Chauhan (2010). The
results of this study support the view that in-vitro plantlet starter materials are appropriate for optimizing
minituber production under aeroponic conditions. However, the experiment needs to be repeated especially with
different potato cultivars so as to come up with useful recommendations.
