Popis: Cucumber is an important horticultural crop widely cultivated for small and medium growers in semiarid regions of the Brazil. In order to evaluate the nutrient solution effect on development and mineral composition of cucumber grown in coconut fiber substrate, an experimental was carried out using completely randomized design with four replications. A standard nutrient solution was prepared following the recommendation of 100% suggested by Furlani for cucumber crop. Concentrations of nutrient solution were to simulate by standard nutrient solution: 12.5, 17, 25; 50 and 100 % (control) and, after the nutrients dilution showed conductivities following: 1.0, 1.2, 1.5, 2.3 and 3.8 dS m- 1, respectively. Seven days after transplanting the variables plant height, stem diameter and number of leaves were recording. For each plot two leaves of cucumber terminal shoot was collected at beginning of flowering (30 days after transplanting) and, macro and micronutrients was analyzed in dry biomass. Growth variables plant height, stem diameter and number of leaves were influenced by the interaction ratio of nutrients in the nutrients solution age of the plants. The cucumber plants were adequately nourished in nitrogen, phosphorus, potassium, calcium, magnesium, copper, manganese, iron and zinc.
