Abstract
Fertilization of 2 cultivars of potato (Solanum tuberosum L.) grown in solution culture with NH4—N resulted in growth reduction, leaf roll, suppression of Ca and Mg uptake, and enhancement of P uptake compared with responses with NO3—N. Calcium and Mg decreased as time under NH4 nutrition increased. Solution pH had little affect on response to N form.Keywords
