CONCLUSIONSThe experiment showed that mineral nitrogen nutrition strongly influenced theproduction of potato microtubers. The mineral nitrogen nutrition is a major limiting factorcontrolling their size.Reducing inorganic nitrogen in the medium had effect in the average microtuberweight or size of the microtubers.REFERENCESAvilla, A., S.M.
