Abstract
Pea is cultivated in the central part of Brazil, in the period of dry winter, demanding for a complete success the use of irrigation in order to supply hydric needs of the plants. Therefore, the present work was developed in order to evaluate the effects of soil water potencial on the production of pea plants (Pisum sativum L.). The experiment was performed in a greenhouse, in pedomaterials from clayed texture, in a complete randomized design, with four treatments based on minimum soil water potentials (-33, -100, -200 and -1500 kPa) and three replications, each one containing two pea plants, Caprice cultivar. The results obtained made it clear that reduction of soil water potential induced a decrease in the number of pods per plant, number of grains per pod, pod dry matter and grain dry matter.Downloads
