The work was carried out in the Engineering Degree in Agricultural Production and Marketing, Universidad Mayor de San Andrés, with the objective of evaluating saturation at the root level in the pea crop, considering that the decrease in oxygen generates physiological problems in the crop. Plant height, leaf area, absolute growth rate, relative and absolute growth rate were evaluated with intervals of seven days, in addition to destructive sampling up to 98 days. The objective was to evaluate the effect of water saturation with three percentages of water replacement and its effect on the growth of the pea plant. For plant height, the AP75% treatment reached 144.0 cm, AP50% with 99.85 cm, AP25% with 99.12 cm. The leaf area was greater in AF75% with 3,509.55 cm2/treatment, AF50% and AF25% with 1,790.47 cm2and 1,717.73 cm2respectively. The TCA75% with 2.30 g/day, followed by the TCA50%, TCA25% treatments with 1.16 g/day and 1.05g/day. The relative growth rate was lower up to 60 days, increasing thereafter. The highest rate corresponds to TCR75%, in the senescence phase it tends to decrease with 0.0430442 g g/day. TAN75% reached 0.00002045 g/cm2/day followed by TAN50% with 0.00001758 g/cm2/day, finally the TAN25% treatment reached 0.00001626 g/cm2/day. With a saturation at 75% of its field capacity, the pea crop presents better growth indicators.
