Minituber potato seed yield as a result of nitrogen rates applied in the substrate

A greenhouse experiment was conducted to evaluate the effects of nitrogen rates on the minituber seed potato yield of cv. Monalisa, which was propagated in vitro. Two tissue-culture-propagated potato plantlets were planted in 3 litre pots with substrate. Five N rates (0, 50, 100, 200 and 400 mg kg-1 of N, as NH4NO3) were evaluated [...]
