Resumo: 	In soilless grown strawberry crops, the nitrogen concentration of the nutrient solution affects plant growth and fruit yield and quality. The present research was conducted to determine the effect of nitrogen concentration in the nutrient solution on plant growth and development and fruit yield and quality of this crop. Treatments consisted of five nutrient solutions at nitrogen concentrations of 6.5 (T1), 8.0 (T2), 9.5 (T3), 11.0 (T4) and 12.5 (T5) mmol L-1, in an entirely randomised experimental design with four replications. Ripe fruit yield was determined during the harvest period from June 6th to November 27th, 2009. Number of leaves, shoot and root dry mass and crown diameter were determined at the later date. Number of leaves, shoot and root dry mass and crown diameter decreased by effect of increasing N concentrations in the nutrient solution. Fruit yield and fruit size fitted a polynomial model, with maximum values at 8.9 mmol N L-1. The N concentration used for the strawberry crop in soilless growing systems can be reduced to 8.9 mmol L-1 without any reduction in fruit yield.
