Abstract

Rubber plants were grown in a greenhouse and sampled at 60, 120, 180 and 240 days of growth. Samples were separated in leaves, stems and roots. Growth rate and nutrients concentrations were analyzed. The highest growth rate was obtained after 180 days of plant growth. Except for iron, the highest nutrient concentrations were determined in the leaves. Nutrient extractions per hectare at the 240 day were: N = 60kg; P = 12kg; K = 27,74kg; Ca = 8,97kg; Mg = 5,32 kg; S = 6,21kg; B = 45,52g; Fe = 544g; Mn = 337,74g and Zn = 77,30g.
