Abstract
The study of absorption and accumulation of nutrients is important to determine the date and quantity of fertilizer for crops. The aim of this study was to evaluate the concentration and accumulation of macronutrients in hydroponic and conventional lettuce, cv. Veronica, during crop development. The statistical design was blocks with six replications in split plot. The main plots were hydroponic and conventional system and the subplots were the dates of harvest. Every seven days plants were harvested and analyzed for N, P, K, Ca, Mg and S. The hydroponic plants had the cycle shorter than conventional plants. Concentration of N, P, K, Ca, Mg and S at the harvest in the plant above ground parts in hydroponic system were 44.80; 8.54; 87.42; 10.29; 3.31; 2.32 g Kg-1 and in conventional system were 38.,24; 5.74; 78.33; 12.23; 3.11 and 3.87 g Kg-1, respectively. The accumulation were 581.10; 110.60; 1,135.76; 133.81; 42.97 and 30.08 mg of N, P, K, Ca, Mg and S by plant in hydroponic system and 372.78; 56.11; 765.84; 119.05; 30.46 and 37.81 mg, respectively, in conventional system.
