Abstract
The effects of different nitrogen forms and combinations in nutrient solution on two cultivars (Marmande and Precodor F1) grown in greenhouse were investigated.
Six treatments were examined: NO3-N, NH4-N, Urea-N, NO3-N + NH4-N (1 : 1), NO3-N + NH4-N3 (2 : 1)4, Urea-N + NO3-N + NH4-N (2 : 1 : 1). The form Urea-N and the combination Urea-N + NO3-N + NH4-N (2 : 1 : 1) showed the highest yield.

The fruit quality did not result different among the treatments.
Also, results about the nutrient concentration in the fruits and in the whole plants are reported.
