Studies were carried out under climate and soil conditions of Savannah region in Central Brazil, aiming to establish an adequate time to stop irrigation on "Caprice" precocius pea cultivar. Final irrigation timing used were 25,30, 35, 40,45,50, 55,and 60 days after planting. Plant cicle, number of pods per plant and rehydration capacity of grains increased linearly with the treatments. Yield increased as final irrigation timing increased, and its maximum value was observed for the treatment 60 days alter planting; two days after the optimum economical time. The number of discolored grains decreased when the irrigations were stopped later in the season. The number of grains per pod, the grain average weight, the germination percentage, and the number of hard grains were not affected by the treatments.
