In this study, it was aimed the determination of macronutrients contents (N, P, K, Ca, Mg and S) in different organs of the hybrid of bell pepper Elisa, under fertigation and protected atmosphere, through eight times of plant extraction. At the end of the experiment it was obtained the contents of macronutrients in the fruit, leaf, stem and root and in the plant as a whole, in each growth stage. The fertilization in the studied cycle, 140 days, was done through localized fertigation (drip system). The experiment was developed in the Department of Natural Resources - Soil Science, FCA-UNESP, Botucatu - SP, Brazil. The experiment consisted of eight treatments (time of plant extraction: 0; 20; 40; 60; 80; 100; 120, and 140 days after the transplant of the seedlings) and four repetitions, being each repetition formed by four plants. The macronutrients contents found in the plant have the following decreasing order: K (39, 9 g kg-1) > N (28,3g kg-1) > Ca (12, 8 g kg-1) > Mg (5, 9 g kg-1) > S (4, 1 g kg-1) > P (3, 7 g kg-1).
