| Resumen en inglés | Yield, fruit quality and nutritional status of cucumber plants cultivated in nutrient solutions, prepared with different nutrient sources, were evaluated. The experiment was carried out in greenhouse, being evaluated two groups of nutrient sources, to compose the nutritive solutions of vegetative growth and two groups to compose the nutritive solutions for fructification. The four treatments were disposed in the randomized blocks design with five replications. The nutritive solutions for vegetative growth were composed of 8; 2; 4; 2; 1 and 1 mmol L-1 of N, P, K, Ca, Mg and S and 35; 19; 21; 4; 0.9 and 0,7 mmol L-1 of Fe, Mn, B, Zn, Cu and Mo, respectively. The nutritive solutions for fructification were composed of 12; 3; 8.6; 3; 1.5; and 1.5 mmol L-1 of N, P, K, Ca, Mg and S, and 59; 28; 31; 4; 1.3; and 0.7 mmol L-1 of Fe, Mn, B, Zn, Cu and Mo, respectively. The phosphorus sources were KH2PO4 and H3PO4. This variation implied in the use of NaNO3, CaCl2 and KCl in the treatments 1 and 2; 3 and 4; and 2 and 4. Aodai cultivar seedlings, 21 days after sowing date (10 cm length), were grown in plastic recipient with 8.6 L of capacity, using a spacing of 0.40 x 0.70 m. Yield, fruit quality and plants nutritional status were evaluated, as well as the partition of Ca, Mg and K in the fruit. There were no significant differences between treatments. The average yield was 3.46 kg plant-1, crop cycle of 87 days corresponding to an average yield of 123 t ha-1 when considering the adopted spacing. Concentration of N, P, K, Ca, Mg and S in the leaves were 4.33; 0.77; 4.07; 6.20; 1.42; and 1.63 dag kg-1, respectively. Concentration of Fe, Mn and Cu in the leaves were 288; 960; and 13 mg kg-1, respectively. The partition pattern of Ca, Mg and K in the fruits was not constant during the evaluation |
