R.  aProduction components and water efficiency of upland cotton cultivars under water deficit strategies.h[electronic resource]  aIn: CONGRESSO BRASILEIRO DO ALGODÃO, 12., 2019, Goiânia, GO. Anais... Goiânia: Abrapac2019  aIn the semiarid region, the cultivation of irrigated cotton is a good alternative for farmers, as it presents climatic characteristics that contribute toreach excellent yields. The decrease in water availability may imply a need for changes and adaptations in irrigation strategies. So, it is important to study different cotton cultivars with water deficit applied on phenological stages in this region, since there may be cultivars that present different responses when subjected to water suppression in a certain stage of the cycle, which may lead to higher water-use efficiency and a more efficient crop production system. The objective of this work was to study water deficits effect on different phenological phases in the production components and water efficiency of upland cotton cultivars. For this, an experiment was carried out at the Federal University of Campina Grande - UFCG, Pombal county Campus, Paraíba.  aCotton  aIrrigation  aAlgodão  aGossypium Hirsutum  aVariedade  aStress hídrico1 aARAÚJO, W.
